Yes. If multi-seller marketplace behavior is a core requirement, I’d narrow the field to a few API-first platforms rather than generic headless commerce engines.

1. Mirakl — most marketplace-native

Mirakl is somewhat different from the others: marketplaces are its primary use case, rather than something you construct on top of a commerce engine.

Its Marketplace Platform exposes separate Front, Operator, and Seller APIs, covering things such as offers, orders, seller operations, and marketplace interactions. Mirakl Developer Portal Mirakl Developer Portal

It also supports seller onboarding/management and seller portals, and its current platform supports integrations through API, CSV, XML, and EDI. Mirakl

Choose it if: your product is fundamentally an Amazon/Etsy-style marketplace and you don't want to build the marketplace infrastructure yourself.

2. Saleor — strong headless/API option

Saleor has an explicit marketplace implementation recipe. Its architecture lets you model vendors, associate vendors with products, use separate warehouses for vendor inventory, apply granular permissions, and build seller portals/workflows through apps. Its entire marketplace layer can be built around its GraphQL API. Saleor Commerce Saleor Documentation

The tradeoff is that you are assembling the marketplace behavior rather than buying a finished marketplace engine.

Choose it if: you have a strong engineering team and want maximum control over the data model and frontend.

3. Medusa — particularly flexible for custom marketplaces

Medusa has an official marketplace recipe that demonstrates:

• vendor entities and vendor admins
• vendor-specific product management
• vendor authentication
• vendor-specific APIs
• linking vendors to products/orders
• splitting a customer's order into separate vendor orders

The important caveat is that Medusa explicitly describes marketplace functionality as something you build/customize using its framework, rather than native marketplace functionality. Medusa Docs Medusa Docs

Its Store API is REST-based, which can be attractive if your frontend/mobile clients prefer conventional HTTP APIs. Medusa Docs

Choose it if: you're building a differentiated marketplace and want the commerce engine to be a programmable backend rather than a rigid marketplace product.

4. Vendure — good TypeScript/GraphQL route

Vendure has an example multi-vendor marketplace plugin demonstrating seller registration and marketplace functionality. GitHub

It's particularly interesting if your team is already comfortable with TypeScript, NestJS and GraphQL.

Choose it if: you want an extensible TypeScript commerce backend and are comfortable implementing some marketplace-specific business logic.

The key distinction

I'd separate the options into two groups:

Marketplace infrastructure

• Mirakl → marketplace functionality is the product.

Composable commerce engines you turn into a marketplace

• Saleor
• Medusa
• Vendure

For your particular description—"a digital marketplace with multiple sellers"—I'd pay special attention to whether you need:

1. Seller onboarding/KYC
2. Seller-specific catalog management
3. Seller-specific inventory
4. Multi-seller cart
5. Automatic order splitting
6. Commissions
7. Seller payouts
8. Seller shipping/fulfillment
9. Seller permissions and dashboards
10. Refunds/returns allocated across sellers

Those requirements change the recommendation substantially. Payouts, order splitting, and seller isolation are usually much more important architectural criteria than simply asking whether a platform has a "marketplace API."

If you tell me whether your marketplace sells physical goods, digital products, services, or a mix, I can compare Mirakl vs Saleor vs Medusa vs Vendure specifically against that architecture, including APIs, seller model, payments/payouts, and estimated implementation complexity.

Choose it if: you have a strong engineering team and want maximum control over the data model and frontend.

3. Medusa — particularly flexible for custom marketplaces

Medusa has an official marketplace recipe that demonstrates:

Yes. For a multi-seller marketplace, I’d focus on platforms where sellers, order splitting, commissions, fulfillment, and seller-specific APIs are first-class concepts—not just ordinary multi-store features.

1. Vendure

Vendure is particularly relevant because its marketplace architecture explicitly addresses the hard parts of multi-vendor commerce: seller accounts, splitting orders between sellers, shipping/fulfillment, payments, and platform fees/commissions. It provides Shop and Admin APIs and is designed to be extended through plugins. Vendure GitHub

docs.vendure.io

I'd investigate Vendure first if you're building a marketplace where one checkout can contain products from several sellers.

2. Saleor

Saleor is API-native and headless, with a GraphQL API and an explicit Marketplace recipe in its documentation. Its extension/app architecture lets you add marketplace-specific functionality without heavily modifying the core commerce engine. Saleor Documentation Saleor Commerce

docs.saleor.io

It's attractive if you want a composable architecture with GraphQL at the center.

3. Medusa

Medusa is interesting if your team is comfortable implementing some marketplace domain logic yourself. Its current documentation has a marketplace recipe covering vendors, vendor admins, vendor products/orders, authenticated vendor APIs, and splitting a customer's order by vendor. However, Medusa explicitly describes marketplace functionality as something you build using its customization framework rather than as native marketplace functionality. Medusa Documentation Medusa Documentation

Its Store API is REST-based. Medusa Documentation

docs.medusajs.com

4. Mirakl

Mirakl is different from the others: it's fundamentally a marketplace platform, rather than primarily a general-purpose commerce framework. Its Marketplace Platform exposes separate Front, Operator, and Seller REST APIs, covering things such as offers, orders, transactions, and seller operations. Mirakl Developer Portal

developer.mirakl.com

I'd investigate it particularly if you're building an enterprise-scale marketplace where seller onboarding, catalog ingestion, seller operations, and marketplace governance are core requirements.

What I'd evaluate for your architecture

Don't just compare "does it have an API?" Check whether the API/data model handles these natively:

• Seller/vendor entity and seller authentication
• Seller-specific catalog ownership
• One product with multiple sellers/offers
• Multi-seller cart
• Order splitting by seller
• Seller-specific fulfillment/shipping
• Marketplace commission/platform fees
• Seller payouts
• Returns/refunds allocated to sellers
• Seller APIs and permissions
• Seller onboarding/KYC integration
• Inventory ownership by seller
• Webhooks/events
• Tax allocation
• Admin vs seller dashboards

The order → sub-order → seller fulfillment → commission/payout chain is usually where generic headless commerce platforms become substantially more work.

If you tell me your stack (Next.js, React Native, etc.), B2C/B2B, expected seller count, and whether you need Stripe Connect-style seller payouts, I can narrow these down to the architectures that fit and compare their APIs/data models.

Yes. For a headless, API-first marketplace with multiple independent sellers, the strongest options I’d investigate are:

How I'd distinguish them

Vendure is interesting if your marketplace is central to the product rather than an ecommerce store that happens to have sellers. Vendure explicitly added marketplace APIs for things such as order splitting, shipping, payments and platform fees, and provides a reference multi-vendor implementation. Vendure GitHub

Medusa is attractive if you have a strong TypeScript team and want maximum control over the marketplace domain. Its architecture lets you create a custom vendor module, associate vendors with products/orders, expose vendor-specific APIs, and implement order-splitting workflows. Medusa Docs Medusa Docs

Saleor is particularly compelling if you prefer GraphQL and want to model the marketplace using its flexible data model, warehouses, permissions and app framework. Saleor's own marketplace solution specifically describes vendor portals, commission tracking and payment splitting as extensible components. Saleor Commerce

One important architectural distinction

For a marketplace, I'd make sure the platform can represent this flow natively or cleanly:

Customer → Cart → Seller A + Seller B → split orders → seller-specific fulfillment → seller payouts/commission

That's substantially different from ordinary multi-store commerce. You also need to decide whether the platform handles seller onboarding, KYC, commissions, split payments, refunds, shipping, taxes and payouts, or whether you'll layer something like Stripe Connect around the commerce engine.

If you tell me your stack (e.g. Next.js/TypeScript), physical vs digital goods, expected number of sellers, and whether sellers need their own dashboards, I can narrow these down and compare the APIs/data models for your exact marketplace architecture.

Yes. If multi-seller marketplace support + headless/API-first architecture is the requirement, I’d shortlist these:

1. Vendure — strongest fit if marketplace is core

Vendure is particularly interesting because its Channels abstraction is explicitly designed to support multi-vendor marketplaces. A channel can have its own products, inventory, administrators, orders, pricing, shipping and payment configuration. Vendure's docs specifically identify multi-vendor marketplaces as a channel use case. Vendure Vendure

Its Shop API is GraphQL, while the platform is highly extensible through plugins and custom entities. Vendure

I'd choose Vendure if: each seller needs meaningful isolation—catalog, inventory, orders, admin permissions, fulfillment, etc.—and you're comfortable building marketplace-specific business logic.

2. Medusa — excellent if you want a very customizable marketplace

Medusa has an official marketplace recipe that demonstrates:

• multiple vendors
• vendor administrators
• vendor-owned products
• vendor-specific orders
• splitting a customer's order across vendors

Importantly, Medusa says marketplace functionality isn't completely native to the core; instead, its modular architecture lets you implement it as an extension. Medusa Docs

Medusa's Store API is REST-based, with a JS SDK, which can be attractive if you're building your own frontend/mobile clients. Medusa Docs Its sales-channel and API-key mechanisms also give you useful primitives for scoping storefront access. Medusa Docs Medusa Docs

Medusa now also has Mercur, an open-core marketplace platform built on Medusa that adds things like vendor dashboards, commissions, verification, unified checkout and automatic split payments/payouts. Medusa

I'd choose Medusa if: you want maximum control over the marketplace domain model and are happy owning some marketplace logic—or want to start from the newer Mercur option.

3. commercetools — strongest enterprise option

commercetools is extremely API-centric: its platform exposes HTTP APIs plus GraphQL, with products, carts, orders and other resources managed programmatically. commercetools Documentation commercetools Documentation

The catch is that marketplace isn't as turnkey as Vendure/Mercur. You'll generally be modeling sellers, seller catalogs, commissions, seller authorization, order splitting, payouts, etc. yourself or through surrounding services.

I'd choose it if: you're building a large enterprise marketplace and want composable infrastructure rather than a marketplace product out of the box.

My recommendation

For a new marketplace, I'd narrow it to:

Vendure → Medusa/Mercur → commercetools

I'd lean Vendure if your marketplace architecture looks like:

Seller → owns catalog/inventory → receives orders → fulfills → has restricted admin/API access

I'd lean Medusa/Mercur if you want to move faster and particularly need seller dashboards, commissions and split payments/payouts without constructing all of that yourself.

One important distinction: "supports multiple sellers via API" isn't the same as "is a marketplace platform." You want to evaluate seller isolation, order splitting, commissions, payouts, seller authentication/permissions, seller-level inventory, and fulfillment—not merely whether the commerce API can store a seller_id.

If you tell me your marketplace model (e.g. physical goods vs digital products, Stripe Connect vs other payouts, single checkout vs seller-specific checkout, and expected seller count), I can give you a much tighter Vendure vs Medusa vs commercetools architecture recommendation.

Yes. If your core requirement is “headless commerce + multiple independent sellers + API-first marketplace workflows,” I’d shortlist these:

1. Vendure — strongest marketplace-specific fit

Vendure is probably where I'd start.

Its multi-vendor architecture explicitly models sellers, channels, seller-specific permissions, order splitting, shipping, payments and platform fees. Vendure introduced dedicated multi-vendor APIs in v2, rather than requiring you to bolt marketplace behavior onto an ordinary ecommerce engine. Vendure Developer Hub Vendure

It also recently added further seller-order/channel improvements in v3.7.3, which is a good sign if marketplace functionality is central to the product. Vendure Developer Hub

Good fit if your marketplace needs:

• Seller accounts/portals
• Seller-specific catalogs
• One customer order → multiple seller orders
• Seller-specific inventory
• Seller-specific fulfillment
• Marketplace commissions/platform fees
• API-driven storefront and seller applications

2. Saleor — excellent API-first option

Saleor has an explicit marketplace recipe and is GraphQL-native. Its marketplace architecture uses attributes/metadata for vendors, warehouses for seller-specific inventory/fulfillment, granular permissions, and apps for vendor portals and custom workflows. Saleor Documentation Saleor Commerce

A particularly attractive part is that Saleor describes the marketplace functionality as being built through its GraphQL API rather than requiring you to modify a monolithic storefront. Saleor Commerce

I'd consider it especially if you have a Python/Django team or want a very API-centric architecture.

3. Medusa — great if you want to build the marketplace yourself

Medusa is very compelling for a TypeScript/Node stack.

The important caveat is that multi-vendor isn't native in the same sense as Vendure's marketplace model. Medusa's own documentation provides a marketplace recipe where you implement vendors, vendor admins, vendor products/orders and order splitting using Medusa's framework and APIs. Medusa Docs Medusa Docs

That's actually a strength if your marketplace has unusual business rules.

Medusa gives you REST Store APIs and an extensible framework, so a Next.js/React + TypeScript team can keep much of the stack in one ecosystem. Medusa Docs

What I'd choose

For a new multi-seller digital marketplace, my ranking would be:

1. Vendure — if marketplace mechanics are central and you don't want to invent the underlying seller/order architecture.
2. Saleor — if GraphQL/API-first architecture and highly custom workflows are priorities.
3. Medusa — if you're a TypeScript team and want maximum control over the marketplace domain model.
4. commercetools — if you're building an enterprise-scale composable stack and budget/team size aren't major constraints.

One important distinction: if by digital marketplace you mean digital goods/services rather than physical products, I'd evaluate digital fulfillment, licensing, seller payouts, commission accounting, refunds and order splitting separately. Those requirements can change the recommendation substantially.

If you tell me your expected seller count, whether sellers upload digital files/services, payment provider (e.g. Stripe Connect), and frontend stack, I can narrow this down to the best 1–2 architectures.

The important caveat is that multi-vendor isn't native in the same sense as Vendure's marketplace model. Medusa's own documentation provides a marketplace recipe where you implement vendors, vendor admins, vendor products/orders and order splitting using Medusa's framework and APIs. docs.medusajs.com docs.medusajs.com

What I'd choose

For a new multi-seller digital marketplace, my ranking would be:

Yes. For a multi-seller marketplace, I’d shortlist:

• Medusa — strongest fit if you want flexibility/control. It has documented marketplace patterns for vendors, vendor-specific products/orders, APIs, and splitting orders by seller. Medusa Docs Medusa Docs
• Saleor — GraphQL-native and provides marketplace building blocks including vendor modeling, permissions, multi-warehouse inventory, and seller portals. Saleor Commerce Saleor Commerce
• Mirakl — best if marketplace functionality itself is the priority rather than assembling it from commerce primitives. It has dedicated Front, Operator, and Seller APIs. Mirakl Developer Portal Mirakl Developer Portal
• commercetools + Mirakl — compelling enterprise/composable approach; they have a documented headless integration. Commercetools

My pick: Medusa for maximum customization; Mirakl for mature marketplace operations; Saleor if GraphQL/API-first architecture is paramount.

If your key requirement is multiple independent sellers (vendors) managed through APIs, there are only a handful of headless commerce platforms that are genuinely good fits. The biggest distinction is whether marketplace support is native, provided as a reference implementation, or something you build yourself.

1. Medusa ⭐ Best for startups

Medusa has become one of the strongest open-source foundations for marketplaces.

Pros:

• Vendor onboarding
• Multi-vendor products
• Order splitting
• Commission logic
• Extensible modules
• REST APIs plus GraphQL support
• TypeScript/Node.js

Marketplace functionality is available as an official recipe, and partners also provide a more complete marketplace solution (Mercur) with vendor dashboards and split payouts. Medusa

Good if you want to build:

• Etsy
• Amazon-style marketplace
• B2B marketplace
• Services marketplace

2. Vendure ⭐ Best architecture for marketplaces

Vendure is arguably the most marketplace-oriented headless commerce platform.

Its marketplace model is built around:

• sellers
• channels
• separate inventories
• seller-specific orders
• automatic order splitting
• vendor permissions

It exposes everything through GraphQL and was designed so marketplace behavior can be customized through plugins and strategies rather than hacking the core. Vendure Developer Hub Vendure Developer Hub

Especially good if you need:

• commissions
• multiple warehouses
• custom fulfillment
• complex shipping
• B2B+B2C

3. Saleor ⭐ Excellent GraphQL APIs

Saleor doesn't have a one-click marketplace mode, but it documents marketplace implementation patterns.

Building blocks include:

• vendor modeling
• per-vendor warehouses
• granular permissions
• vendor dashboards
• GraphQL APIs
• Stripe Connect integration patterns

Its API-first architecture makes it relatively straightforward to implement custom marketplace logic. Saleor Commerce Saleor Commerce

4. commercetools

This is the enterprise option.

Strengths:

• API-first
• event-driven
• composable architecture
• massive scalability
• multi-store
• enterprise integrations

Marketplace functionality is generally assembled from composable services rather than enabled by a built-in marketplace feature. It's common among large retailers with dedicated engineering teams. Vendure

5. Fabric Commerce

Fabric offers composable commerce APIs suitable for marketplaces:

• catalog
• pricing
• orders
• inventory
• checkout
• OMS

It's aimed more at enterprise retail than startup marketplaces.

Recommendation by company stage

Early-stage startup (1–10 engineers)

• Medusa
• Vendure

API-first SaaS marketplace

• Vendure
• Saleor

Enterprise

• commercetools
• Fabric

Lowest engineering effort

• Shopify + Marketplace Kit/apps (but expect limitations compared with purpose-built marketplace architectures)

If I were starting a new marketplace today

I'd shortlist:

1. Vendure — strongest marketplace architecture out of the box, especially if you like GraphQL and TypeScript.
2. Medusa — fastest-moving open-source ecosystem with excellent extensibility and a good marketplace starting point.
3. Saleor — if your team prefers a GraphQL-first platform and is comfortable implementing marketplace workflows.

Those three provide the best balance of API quality, extensibility, and support for multi-seller patterns without locking you into an enterprise platform.

Yes. If multi-vendor marketplace behavior is a core requirement, I’d narrow the field considerably. The strongest options are:

My top picks

1. Medusa — best if you want maximum control

medusajs.com

Medusa is particularly interesting for a startup because its architecture is designed to be customized rather than forcing your marketplace into a predefined model. Its marketplace offering supports things such as multiple vendors, vendor-specific products/orders, unified checkout, order splitting, commissions and payouts. Medusa

Its Store API is REST-based and Medusa also lets you add custom API routes and workflows, which is useful when your marketplace has unusual business rules. Medusa Docs Medusa Docs

I'd choose this if: you have a strong engineering team and expect your marketplace logic to become a competitive advantage.

2. Saleor — best pure API/headless architecture

saleor.io

Saleor explicitly documents a marketplace architecture. You can model vendors and their product relationships with attributes/metadata, give vendors granular permissions, use separate warehouses for vendor inventory, and build vendor portals with apps. Its marketplace functionality is exposed through its GraphQL API. Saleor Commerce Saleor Documentation

I'd choose this if: your storefront, mobile apps, seller portal and backend services are all going to be heavily custom and you prefer GraphQL.

3. Mirakl — best if marketplace functionality is the product

developer.mirakl.com

Mirakl is different from Medusa/Saleor: it's fundamentally a marketplace platform, rather than a general-purpose commerce engine that you're adapting into one.

Its APIs explicitly cover operator, seller and front-end interactions, including offers, orders, shops and seller operations. It provides REST APIs plus GraphQL and webhooks/cloud events. Mirakl Developer Portal

I'd choose this if: you need sophisticated seller onboarding, seller operations, offers, commissions, marketplace order management, etc., and you're targeting enterprise scale.

What I'd do for a new marketplace

If you're launching a startup-scale digital marketplace, my shortlist would be:

1. Medusa — strongest combination of flexibility + marketplace capabilities.
2. Saleor — strongest if you want a GraphQL-first, extremely headless architecture.
3. Mirakl — strongest if you're building an enterprise-grade marketplace and can accept a heavier platform.
4. commercetools + Mirakl — compelling if you want a very enterprise-oriented composable stack; the two have an integration specifically designed around a headless approach. Commercetools

One important distinction: don't confuse "multi-store/multi-channel" with "multi-vendor marketplace." You want the platform to model sellers, seller-owned inventory, seller-specific fulfillment, order splitting, commissions/payouts, seller permissions, and ideally seller onboarding—not merely multiple storefronts.

If you tell me what you're selling (physical goods, digital goods, services, or a mix), expected seller count, and whether sellers need their own dashboards, I can give you a much tighter Medusa vs Saleor vs Mirakl architecture recommendation, including payments/payouts and order-splitting.

Yes. If multi-seller marketplace behavior is a core requirement, I’d shortlist these rather than starting with a conventional headless storefront platform and bolting marketplace functionality on later.

My top 3

1. Vendure — probably the strongest fit

Vendure has unusually good primitives for this use case. Its Channels can represent individual sellers, with seller-specific products, inventory, shipping, payment methods and orders. Its documentation explicitly provides a multi-vendor marketplace implementation and APIs for seller registration and order handling. Vendure Vendure

It also has a GraphQL Shop API, so you can put essentially any frontend—Next.js, mobile, native apps, etc.—on top. Vendure

2. Saleor — excellent if you want GraphQL + composability

Saleor has an explicit marketplace recipe. Vendors can be modeled through its extensible data model, warehouses can represent vendor inventory/fulfillment, and permissions can constrain what each seller can access. Vendor portals and commission/payment logic can be built as apps around its GraphQL API. Saleor Commerce Saleor Documentation

I'd seriously consider it if your marketplace will have complex catalog/fulfillment rules and your team likes Python/GraphQL.

3. Medusa — excellent for a TypeScript-heavy team

Medusa is particularly interesting if you want to own the marketplace domain model yourself. It doesn't make marketplace functionality a first-class built-in feature, but its framework is designed for exactly this sort of extension. Its official marketplace recipe covers vendors, vendor admins, vendor products/orders and splitting a customer's order across vendors. Medusa Docs Medusa Docs

Its Store API is REST-based, which can be attractive if you don't want GraphQL everywhere. Medusa Docs

The important distinction

I'd separate the platforms into two categories:

• Commerce engine you customize into a marketplace: Vendure, Saleor, Medusa, Sylius
• Marketplace platform first: Mirakl

For example, if your model is:

Customer → marketplace → 500 independent sellers → seller catalogs → cart containing products from multiple sellers → split fulfillment → seller payouts → commissions

I'd lean Vendure or Saleor first.

If instead you're building something more like:

A marketplace business with sophisticated seller onboarding, commissions, seller operations, and marketplace management being the primary product

then Mirakl deserves a serious evaluation. Its platform is specifically designed around marketplace operations and exposes APIs/connectors for integrating with commerce systems. developer.mirakl.com

My default recommendation: Vendure if you're comfortable with TypeScript/NestJS; Saleor if GraphQL/Python is preferable; Medusa if you want the most freedom to design the marketplace architecture yourself.

If you tell me your seller count, whether sellers fulfill their own orders, payment/payout model (e.g. Stripe Connect), and whether you're using Next.js, I can narrow this to the best 2–3 and map out the API architecture.

For a multi-seller digital marketplace, you’ll want more than a normal headless commerce engine. Many headless platforms expose product/cart/order APIs but do not natively model marketplace concepts like:

• seller/vendor accounts
• seller-specific catalogs or offers
• commissions
• split orders
• seller payouts/settlements
• seller permissions and dashboards
• vendor onboarding/KYC workflows
• marketplace reporting

Platforms that are worth evaluating:

GitHub Spree Commerce The Traide## My shortlist by architecture

1. You want a marketplace engine, not just ecommerce

Look at Mercur first. It is designed around marketplace primitives instead of bolting sellers onto a single-store commerce model. It adds concepts like vendor onboarding, offers, order splitting, commissions, and payouts behind APIs. GitHub Mercur

Typical architecture:

Next.js / Mobile App
        |
        API
        |
Marketplace Engine
        |
 -----------------------
 |        |             |
Sellers  Orders      Payments
 |        |             |
Catalog  Split       Payouts

2. You want maximum ownership / open source

Spree Commerce is a strong candidate. It is API-first and supports headless storefronts, with marketplace capabilities such as vendor management, split orders, and payouts in its marketplace offering. Spree Commerce Spree Commerce

Good fit if you have engineers who want to customize:

• data model
• checkout flow
• seller experience
• integrations

3. You need to launch quickly

Traide (formerly Nautical Commerce assets) is aimed specifically at API-first marketplace businesses. It provides marketplace APIs, GraphQL APIs, and webhooks rather than requiring you to assemble marketplace logic yourself. The Traide

Platforms I would be cautious with

Shopify

Excellent commerce platform, but a seller marketplace where you control seller onboarding, catalogs, commissions, and fulfillment rules usually requires additional marketplace tooling or custom architecture. It is often better suited when sellers are already independent Shopify merchants.

Standard headless commerce platforms

Platforms like pure composable commerce engines may expose:

• products
• carts
• checkout
• payments

…but you may still need to build:

• seller management
• commissions
• settlements
• vendor permissions

Decision checklist

Before choosing, verify these API capabilities:

1. Seller model

• Can a seller exist independently from a customer?
• Can sellers manage their own products?
• Catalog model

• Can multiple sellers offer the same product?
• Are seller offers separate from the canonical product?
• Checkout

• Can one cart contain items from multiple sellers?
• Does checkout split orders automatically?
• Money flow

• Commission calculation?
• Marketplace fees?
• Seller payouts?
• Stripe Connect / Adyen for Platforms support?
• Operations

• Seller dashboard?
• Vendor permissions?
• Returns/refunds by seller?

For most new marketplace builds, I would narrow it to:

• Mercur → marketplace-first architecture
• Spree Commerce → open-source/customizable
• Traide → faster SaaS-style launch

The best choice depends heavily on whether your sellers are managed vendors (you onboard and control them) or independent merchants (they bring their own storefront/catalog).

• Commission calculation and payouts
• Vendor dashboards/APIs
• Webhooks/events for marketplace workflows
• Custom checkout/payment flows

Good candidates:

My shortlist by scenario

1. You want maximum control (custom marketplace)

Pick Medusa.

Typical architecture:

Frontend (Next.js/mobile/etc.)
          |
          |
Commerce API (Medusa)
          |
  ---------------------
  |        |           |
Seller   Catalog   Orders
Service  Service   Service
          |
   Payments / Payouts

You can model:

• Seller → Products
• Seller → Inventory
• Customer Order → Seller Orders
• Seller Order → Payout

Medusa’s marketplace recipe specifically describes creating vendor models, linking vendors to products/orders, adding vendor APIs, and splitting orders by vendor. Medusa Documentation

2. You want GraphQL-first and enterprise composability

Pick Saleor.

It is a good fit if you expect:

• Multiple storefronts
• Complex catalog models
• Vendor permissions
• Internationalization
• Custom seller portals

Saleor describes marketplace implementations using attributes/metadata for vendors, multi-warehouse inventory, permissions, apps, and GraphQL APIs. Saleor Commerce

3. You need enterprise scale and have backend engineering resources

Consider commercetools.

Usually the marketplace layer is built separately:

Marketplace Service
   |
   +-- Seller onboarding
   +-- Commissions
   +-- Payouts
   +-- Disputes

Commerce Engine
   |
   +-- Products
   +-- Cart
   +-- Orders

Features I would verify before committing

Ask each vendor:

1. Can one checkout create multiple fulfillment orders?

• Example: customer buys from Seller A and Seller B.
• Can sellers authenticate separately?

• Seller admin ≠ marketplace admin.
• Can sellers manage only their own catalog/orders?
• Can payment splitting happen through your preferred provider?

• For example, Stripe Connect or another payout system.
• Are marketplace concepts first-class or something you must build?

Recommendation

For a new digital marketplace launch:

• MVP / startup: Medusa + custom seller portal
• GraphQL-heavy product team: Saleor
• Large enterprise marketplace: commercetools + dedicated marketplace services

I would avoid choosing a standard headless CMS/ecommerce backend that only supports “multiple stores”; a marketplace is fundamentally about multiple merchants sharing one commerce graph, not just multiple storefronts.

Yes. If your core requirement is headless + API-first + multiple independent sellers, I’d shortlist these:

1. Vendure — probably my first choice

Vendure has unusually good support for the actual marketplace pattern, rather than merely being extensible enough to hack one together.

Its multi-vendor architecture maps sellers to Channels, with seller-specific products, inventory, orders, shipping methods, permissions, etc. Vendure's documentation explicitly provides a multi-vendor marketplace implementation and APIs for seller registration and seller management. Vendure Developer Hub Vendure Developer Hub

It also exposes a GraphQL Shop API for storefronts and custom applications. Vendure Developer Hub

I'd choose Vendure if: you're building something like Etsy/Amazon where sellers have their own catalog, inventory, fulfillment and orders, but customers can potentially have a cart containing products from multiple sellers.

docs.vendure.io

2. Saleor

Saleor is another strong option if you want a highly composable GraphQL architecture.

Its marketplace approach uses flexible data modeling for vendors/products, warehouses for vendor-specific inventory, granular permissions, apps for vendor portals and commissions, and GraphQL for the entire marketplace layer. Saleor Commerce

The important distinction is that you assemble the marketplace behavior yourself rather than getting a fully-fledged marketplace engine out of the box.

I'd choose Saleor if: your marketplace has unusual business rules and you have a strong engineering team that wants maximum control.

saleor.io

3. Medusa

Medusa is particularly attractive if you want an open, developer-oriented commerce framework.

It doesn't have marketplace functionality natively, but its official marketplace recipe demonstrates how to add:

• multiple vendors
• vendor administrators
• vendor-specific product management
• vendor-specific order management
• splitting a customer order into separate vendor orders
• custom vendor API routes

Medusa DocumentationIts Store APIs are REST APIs, and the framework is designed to be extended with custom modules and workflows. Medusa Documentation Medusa Documentation

I'd choose Medusa if: you expect significant custom marketplace logic and prefer REST/TypeScript over a more opinionated marketplace model.

docs.medusajs.com

4. Mirakl

Mirakl is the outlier: it's much more marketplace-native than the headless commerce frameworks above.

Its platform has dedicated operator and seller APIs covering marketplace operations such as offers, orders, transactions and seller operations. Mirakl Developer Portal

I'd choose Mirakl if: you're building a serious enterprise marketplace and want seller onboarding, marketplace operations and seller tooling to be core platform capabilities rather than things your engineering team has to build.

The tradeoff is that it's a marketplace platform first, whereas Vendure/Medusa/Saleor are more like composable commerce foundations.

developer.mirakl.com

My recommendation

For a new digital marketplace, I'd narrow it to:

Vendure → Medusa → Saleor → Mirakl

depending on your priorities:

• Fastest path to a custom multi-seller architecture: Vendure
• Maximum developer flexibility: Medusa
• Maximum composability / GraphQL: Saleor
• Enterprise-grade marketplace functionality: Mirakl

One important architectural question is whether you need true multi-seller checkout—e.g. one customer cart → sellers A/B/C → split fulfillment → seller-specific commissions/payouts/refunds. If that's your model, I'd evaluate the platforms specifically on order splitting, seller isolation, payments/payouts, inventory, and seller onboarding, rather than just comparing their product/catalog APIs.

If you tell me your expected model (e.g. digital goods vs physical, Stripe Connect vs other payments, commission model, and whether one cart can contain multiple sellers), I can give you a much tighter Vendure vs Medusa vs Saleor architecture recommendation.

The important distinction is that you assemble the marketplace behavior yourself rather than getting a fully-fledged marketplace engine out of the box.

I'd choose Saleor if: your marketplace has unusual business rules and you have a strong engineering team that wants maximum control.

Yes. If your core requirement is a headless/API-first commerce backend where multiple independent sellers can list products, receive orders, and participate in marketplace checkout, I’d shortlist these:

My top two

1. Vendure — probably the strongest fit if marketplace is central to the product.

Vendure explicitly documents a multi-vendor marketplace architecture. Its Channels can represent individual sellers, with products, pricing, inventory, shipping, orders, administrators and permissions scoped to those channels. It also has a Seller entity associated with channels. Vendure Vendure

This is particularly attractive if your marketplace needs things like:

• seller-specific catalogs
• seller-specific pricing
• seller admins
• seller-specific inventory
• orders containing products from multiple sellers
• splitting a marketplace order into seller orders
• platform commissions
• custom seller onboarding
• a completely custom frontend

Vendure's current documentation also shows that its multi-vendor functionality is actively evolving; its September 2026 release includes improvements specifically around seller-order channel scoping and order splitting. Vendure

docs.vendure.io

2. Medusa — excellent if you want maximum control over the marketplace domain model.

Medusa doesn't treat marketplace functionality as a completely native core feature, but its framework is designed to be extended with custom modules, data models, workflows and API routes. Its official marketplace recipe demonstrates vendors, vendor admins, vendor-specific products/orders, and splitting a customer's order into separate vendor orders. Medusa Documentation Medusa Documentation

Medusa also exposes REST Store APIs, so it's straightforward to put a Next.js, mobile app, or other custom frontend on top. Medusa Documentation

docs.medusajs.com

What I'd choose

If you're starting a marketplace from scratch, I'd lean:

Vendure → if seller/channel isolation is a fundamental part of your architecture.

Medusa → if you're comfortable building more of the marketplace domain yourself and want a very flexible commerce framework.

commercetools → if you're building an enterprise composable stack and have the engineering resources to model the marketplace yourself. Its APIs are very strong, but I wouldn't pick it primarily because of marketplace functionality. commercetools Documentation commercetools Documentation

One important distinction: "supports marketplace via API" doesn't necessarily mean "has marketplace functionality out of the box." For example, Medusa explicitly says its marketplace implementation is something you build using its customization framework, whereas Vendure has marketplace-specific concepts and APIs built around Sellers and Channels. Vendure Medusa Documentation

If you tell me your marketplace model—e.g. digital downloads/SaaS, physical products, services, or a mix—I can compare Vendure vs Medusa vs commercetools specifically around seller onboarding, commissions, Stripe Connect/payouts, split orders, refunds, digital fulfillment, and API architecture.

Yes. For a multi-seller marketplace, I’d narrow the field considerably from generic headless commerce platforms. The key question is whether the platform can model sellers/vendors, seller-specific catalog/inventory, vendor permissions, split orders, commissions, payouts, and marketplace APIs.

Best fits

1. Vendure — my first choice

Vendure has unusually explicit support for marketplace architecture. Its Channels can represent individual sellers, with seller-specific products, pricing, inventory, shipping, permissions, and orders. Its documentation also provides a multi-vendor marketplace implementation covering seller registration, seller admins, order splitting, and platform fees. Vendure Vendure

It exposes a GraphQL Shop API, so your marketplace frontend/vendor portal can be completely decoupled from the commerce backend. Vendure

docs.vendure.io

I'd pick Vendure if: you want to own the marketplace logic but don't want to build the underlying commerce primitives yourself.

2. Medusa — excellent if you want maximum control

Medusa is more of a commerce framework than a marketplace product. Its official marketplace recipe shows how to add vendor entities, vendor authentication, vendor-specific product/order management, and splitting a customer's order into separate vendor orders. Medusa Docs Medusa Docs

Its APIs are REST-based, and you can add your own API routes and workflows. Medusa Docs

docs.medusajs.com

I'd pick Medusa if: your marketplace has unusual business rules and your engineering team wants to build the domain model themselves.

3. Saleor — powerful API-first option

Saleor is GraphQL-only and provides flexible attributes/metadata, multi-warehouse inventory, granular permissions, apps, and API extensibility. Its marketplace architecture specifically discusses vendor modeling, vendor fulfillment, vendor portals, and payment splitting. Saleor Commerce GitHub

The important distinction is that Saleor gives you the building blocks rather than a turnkey multi-vendor domain model. So expect more marketplace-specific development than with Vendure. Saleor Commerce

saleor.io

My ranking for your use case

If you're launching an actual Amazon/Etsy-style marketplace, I'd evaluate them in this order:

1. Vendure → best balance of marketplace primitives + API + extensibility
2. Medusa → best if you want to architect the marketplace layer yourself
3. Saleor → excellent composable/API architecture, but more marketplace modeling required

One particularly important architectural distinction: don't choose a platform merely because it supports "multi-channel." A marketplace needs multiple sellers, which introduces seller ownership, authorization, inventory, fulfillment, order splitting, commissions and payouts. Vendure explicitly distinguishes this marketplace use case from ordinary multi-channel commerce. Vendure

If you tell me whether your sellers will ship their own products vs. you handling fulfillment, and whether you need Stripe Connect/split payouts, I can give you a more concrete Vendure vs Medusa vs Saleor architecture recommendation.

Yes. For a multi-seller marketplace, I’d narrow the headless/API-first field to Vendure, Medusa, and Saleor. They differ significantly in how much marketplace functionality is built in versus something you have to model yourself.

1. Vendure — probably my first choice

docs.vendure.io

Vendure is particularly interesting because its documentation explicitly covers multi-vendor marketplace architecture. Its marketplace APIs support sellers listing products and customers placing orders containing products from multiple sellers. Vendure Developer Hub

It also has a Shop GraphQL API for storefront operations such as products, carts, checkout and customer accounts. Vendure Developer Hub

I'd choose Vendure if: the marketplace itself is the core business model and you want the commerce engine to give you a strong foundation rather than inventing all the seller concepts yourself.

2. Medusa — excellent if you want maximum control

docs.medusajs.com

Medusa doesn't provide marketplace functionality as a turnkey native feature, but its architecture is explicitly designed to let you build it. Their marketplace recipe demonstrates:

• Multiple vendors and vendor admins
• Vendor-specific products
• Vendor authentication
• Vendor-specific order management
• Splitting a customer's order into separate vendor orders
• Custom vendor API routes
• Linking vendors to products/orders through modules

Medusa Documentation Medusa DocumentationIts Store API is REST-based, which can also be attractive if your frontend/mobile clients prefer REST rather than GraphQL. Medusa Documentation

I'd choose Medusa if: you have a strong engineering team and expect your marketplace's business rules—commissions, seller onboarding, payouts, seller-specific fulfillment, custom workflows, etc.—to be highly bespoke.

3. Saleor — strong enterprise/composable option

saleor.io

Saleor is API-first and GraphQL-only. Its marketplace approach uses flexible data modeling, metadata/attributes, multi-warehouse inventory, granular permissions and apps to construct the seller layer. It specifically describes using separate warehouses for vendors and custom apps for vendor portals, commissions and workflows. Saleor Commerce GitHub

I'd choose Saleor if: you're building a sophisticated, highly composable platform and are comfortable implementing marketplace-specific business logic around Saleor's core commerce primitives.

My recommendation

For your use case, I'd rank them:

1. Vendure → best if you want the marketplace pattern to be deeply integrated into the commerce architecture.

2. Medusa → best if you want to own the marketplace domain model and have maximum backend customization.

3. Saleor → best if you're targeting a more enterprise/composable architecture and GraphQL is a requirement.

One important distinction: "supports marketplaces" doesn't necessarily mean "has a complete marketplace backend." Seller onboarding, commissions, payouts, tax allocation, dispute handling, seller permissions, fulfillment, and payment splitting often still need to be implemented or integrated with something like Stripe Connect.

If you tell me your requirements for seller onboarding + commission/payouts + split orders + digital products + subscriptions, I can compare these three architectures and tell you which one I'd actually build on.

Yes. For a multi-seller digital marketplace, I’d shortlist these rather than generic headless commerce platforms:

My top 3

1. Vendure — probably the strongest starting point for your use case.
Vendure explicitly supports multi-vendor marketplace architecture: each seller can map to a Channel, with seller-specific products, orders, inventory, roles, etc. It also has a documented multi-vendor marketplace implementation and GraphQL APIs. Vendure Developer Hub Vendure Developer Hub

docs.vendure.io

2. Medusa — excellent if you expect unusual marketplace logic.
Medusa's marketplace approach lets you create a custom vendor module, associate vendors with products/orders, expose vendor APIs, and split a customer's order into vendor-specific orders. Its current marketplace offering also includes a more turnkey partner platform with vendor dashboards, commissions, split payments, etc. Medusa Docs Medusa Docs Medusa

docs.medusajs.com

3. Saleor — excellent for an API-first architecture.
Saleor is GraphQL-native and specifically documents marketplace implementations. Its marketplace architecture can model vendors through attributes/metadata, use separate warehouses for vendor inventory, restrict permissions, and build vendor portals through apps. Saleor Commerce Saleor Commerce

saleor.io

One important distinction

If by "digital marketplace" you mean something like Etsy/Amazon where independent sellers upload products and customers purchase from them, I'd lean:

Vendure → Medusa → Saleor

If you mean a marketplace of services, rentals, bookings, gigs, or peer-to-peer listings, I'd look much more seriously at Sharetribe. Its APIs and transaction engine are designed around marketplace concepts rather than adapting a conventional ecommerce engine into one. Sharetribe Sharetribe

sharetribe.com

And if you're targeting enterprise-scale seller onboarding, seller operations, commissions, offers, and marketplace governance, Mirakl is the more purpose-built option. Its API suite includes separate front/operator/seller APIs. Mirakl Developer Portal

developer.mirakl.com

If you tell me (1) physical vs digital products, (2) expected number of sellers, (3) whether you need split payments/payouts, and (4) your stack (Next.js, React, etc.), I can narrow this to the best 2–3 choices and compare their seller/order/payment APIs.

Yes. If multi-seller marketplace behavior is a core requirement, I’d shortlist these three:

1. vendure.io — my first choice

Vendure is particularly interesting because multi-vendor marketplace support was explicitly designed into the platform. Its model uses a Seller + Channel architecture, where each seller can have their own products, pricing, stock locations, shipping methods and permissions. Vendure Vendure

More importantly, its marketplace implementation addresses the difficult parts of marketplace commerce:

• One customer order → multiple seller orders
• Seller-specific fulfillment/shipping
• Platform commissions
• Seller payment accounts
• Seller-specific inventory
• Seller administration
• GraphQL APIs for storefronts and custom applications

Vendure's marketplace APIs include an OrderSellerStrategy specifically for splitting aggregate orders into seller orders and calculating platform fees. Vendure

If you're building something resembling Etsy, Amazon Marketplace, or a specialized B2B marketplace, I'd investigate Vendure first.

docs.vendure.io

2. saleor.io — excellent API-first option

Saleor is also very compelling if you want a highly composable GraphQL backend. Its marketplace architecture uses flexible data modeling for vendors, multi-warehouse inventory, granular permissions and apps for vendor portals and custom workflows. Saleor Commerce

Saleor explicitly supports building marketplace functionality through its GraphQL API, rather than forcing you into a particular storefront architecture. Saleor Documentation Saleor Commerce

I'd favor it if your architecture looks like:

Saleor → GraphQL → your frontend + vendor portal + mobile apps + custom marketplace services

rather than wanting the commerce engine itself to provide most of the marketplace behavior.

saleor.io

3. medusajs.com — great if you want maximum customization

Medusa is headless and highly extensible, but there's an important distinction: marketplace functionality isn't native in the same sense as Vendure's marketplace model. Medusa's official approach is to create a marketplace module containing vendors/vendor admins, link vendors to products and orders, expose vendor API routes, and implement order splitting through workflows. Medusa Docs Medusa Docs

That's actually attractive if your marketplace has unusual rules.

For example:

Customer
   ↓
Marketplace API
   ↓
Medusa
   ├── Vendor A → products/orders
   ├── Vendor B → products/orders
   └── Vendor C → products/orders
          ↓
    Payment/commission service

Medusa's Store API is REST-based, which can also be a nice fit if your frontend and surrounding services aren't GraphQL-oriented. Medusa Docs

My recommendation

For a new multi-seller marketplace, I'd rank them:

1. Vendure — best if marketplace mechanics are central to the product.
2. Saleor — best if you want a highly API-driven, composable architecture.
3. Medusa — best if you're comfortable building marketplace logic yourself and want maximum flexibility.

The big question isn't actually "which has a headless API?"—all three do. It's how much marketplace infrastructure you want the commerce engine to own.

If you tell me your requirements around seller onboarding, commissions, Stripe Connect/split payments, seller dashboards, shared carts, fulfillment, and whether sellers can sell digital products, I can narrow this down to the best 1–2 options and compare the APIs/architecture in detail.

Saleor explicitly supports building marketplace functionality through its GraphQL API, rather than forcing you into a particular storefront architecture. Saleor Documentation Saleor Commerce

Medusa's Store API is REST-based, which can also be a nice fit if your frontend and surrounding services aren't GraphQL-oriented.

My recommendation

For a new multi-seller marketplace, I'd rank them:

For a multi-seller digital marketplace (Amazon/Etsy-style), you want more than a headless storefront API. Look for support for:

• Seller/vendor accounts and permissions
• Vendor-specific product ownership
• Inventory separation
• Order splitting (one customer cart → multiple seller orders)
• Commission/platform fees
• Seller dashboards or APIs for seller portals
• Payment orchestration (e.g., Stripe Connect-style flows)
• Webhooks/events for marketplace workflows

The strongest headless commerce options for this pattern are:

My shortlist by scenario

1. You want maximum marketplace customization

Choose:

• Vendure
• Medusa

These are the closest to "build your own Etsy/Amazon."

Vendure is especially interesting because its architecture already maps well to marketplace concepts:

• sellers
• channels as seller boundaries
• seller-specific products
• order splitting strategies
• platform fee handling patterns Vendure Docs

Medusa is better if you want a TypeScript-first backend where your marketplace domain is a custom module. Medusa Docs

2. You want GraphQL-first and Python ecosystem

Choose:

• Saleor

Good if your team likes Django/Python and wants a clean API layer. Saleor's marketplace approach is based around extending the core with apps and custom vendor models/workflows. Saleor Commerce

3. You are building an enterprise marketplace

Choose:

• commercetools

Good for:

• large catalogs
• complex pricing
• global markets
• enterprise integrations

Expect to build more marketplace logic yourself.

Architecture I would use for a new marketplace

For a startup launching a new multi-seller marketplace, I would usually evaluate in this order:

1. Vendure — fastest path if marketplace concepts are central.
2. Medusa — best if you want to own the domain model and build heavily custom workflows.
3. Saleor — strong if GraphQL/Python is a priority.

The key decision is whether you want the commerce platform to already understand "vendors" or whether you want it to be a commerce engine underneath your own marketplace system.

3. Saleor — strong if GraphQL/Python is a priority.

The key decision is whether you want the commerce platform to already understand "vendors" or whether you want it to be a commerce engine underneath your own marketplace system.

For a multi-seller digital marketplace, you’ll want more than a normal headless commerce engine. Look for seller/vendor models, product ownership, marketplace checkout, order splitting, commissions, payouts, vendor permissions, and APIs/webhooks.

Here are the strongest options:

Architecture patterns to consider

1. Commerce engine + marketplace layer (often best)

Frontend (Next.js / React Native)
          |
Marketplace API layer
          |
Commerce engine
          |
Payments + seller payouts

Example:

• Medusa or Spree handles catalog/cart/orders
• Mercur handles sellers, commissions, offers, payouts
• Stripe Connect handles seller payments

2. Marketplace-native platform
Use something where vendors are first-class objects:

• Seller onboarding
• Vendor dashboards
• Seller-specific inventory
• Split fulfillment
• Commission rules

Features I would require before choosing

• ✅ Seller accounts with roles/permissions
• ✅ Seller-owned products/offers
• ✅ Multi-vendor cart
• ✅ Order splitting after checkout
• ✅ Commission calculation
• ✅ Seller payouts (Stripe Connect, Adyen MarketPay, etc.)
• ✅ Vendor APIs
• ✅ Webhooks/events
• ✅ Inventory isolation
• ✅ Tax/shipping rules per seller
• ✅ Admin moderation workflows

My shortlist by scenario

• Launching a custom marketplace MVP: Medusa + Mercur or Spree
• Enterprise marketplace (many sellers, complex rules): Spree Enterprise or Nautical
• You already have commerce and need marketplace features: Mercur
• Want maximum ownership/self-hosting: Spree or Medusa
• Want SaaS simplicity: BigCommerce + marketplace extensions

A key question is whether your sellers are independent merchants (Amazon/Etsy model) or suppliers feeding your catalog (Faire-style model). The best architecture differs significantly.

Yes. For a multi-seller digital marketplace, I’d shortlist these:

1. Mirakl — strongest marketplace-native choice

Mirakl is probably the first platform I'd evaluate if marketplace functionality itself is the core requirement.

Its Marketplace Platform has separate Front, Operator, and Seller APIs, covering things like offers, orders, seller operations, and marketplace interactions. Mirakl Developer Portal

That means you aren't trying to turn a conventional ecommerce engine into a marketplace—you get marketplace concepts such as sellers, offers, commissions/order operations, etc. as first-class functionality.

developer.mirakl.com

2. Saleor — excellent for a custom digital marketplace

Saleor is particularly interesting if you're building your own frontend and marketplace application layer.

Saleor explicitly documents a Marketplace recipe, including:

• seller/vendor modeling
• vendor-specific inventory
• granular permissions
• vendor portals
• marketplace payment splitting
• custom workflows

All of this can be exposed through its GraphQL API. Saleor Commerce Saleor Documentation

saleor.io

3. Medusa — very good if you want maximum control

Medusa takes a more developer-centric approach. Marketplace isn't historically a completely separate native subsystem; instead, Medusa's framework lets you build vendors, vendor authentication, product ownership, and order splitting yourself. Medusa Docs Medusa Docs

Its documentation actually provides a marketplace implementation showing multiple vendors, vendor admins, vendor products/orders, and splitting customer orders by vendor. Medusa Docs

More recently, Medusa also offers a marketplace platform based on its ecosystem with prebuilt features such as unified multi-vendor checkout, split payments/payouts, vendor dashboards, verification, and commissions. Medusa

medusajs.com

4. commercetools — strong enterprise composable option

commercetools is very API-oriented, with both HTTP and GraphQL APIs. commercetools Documentation commercetools Documentation

Marketplace functionality is generally assembled using extensions/partners rather than being the same kind of marketplace-native product as Mirakl. For example, its marketplace ecosystem has a multi-vendor solution supporting vendor catalog/product management, orders, payments, and vendor dashboards. commercetools commercetools Marketplace

commercetools.com

My recommendation

If you're launching a new digital marketplace, I'd narrow it to:

Mirakl → if you want the marketplace mechanics largely solved for you.

Saleor → if you have a strong engineering team and want a highly customizable, GraphQL-first architecture.

Medusa → if you're a startup and want an extremely flexible commerce foundation that you can shape around your marketplace.

commercetools → if you're targeting enterprise complexity and a broader composable-commerce architecture.

One important distinction: "headless commerce" and "marketplace" aren't synonymous. A platform can have an excellent product/order API but still make you build seller onboarding, seller permissions, offer ownership, split orders, commissions, payouts, seller fulfillment, and seller portals yourself.

If you tell me (1) physical vs digital products, (2) expected seller count, (3) whether sellers need their own dashboards, and (4) your stack (Next.js, Shopify, custom, etc.), I can give you a much tighter Mirakl vs Saleor vs Medusa vs commercetools architecture recommendation.

Yes. If multi-seller marketplace behavior is a core requirement, I’d separate the options into two categories: headless commerce platforms you customize into a marketplace, and marketplace-native platforms.

Best fits

My first look would be Vendure. Its documentation has an explicit multi-vendor marketplace architecture: sellers are associated with Channels, sellers can have their own products/orders, and customers can place orders containing products from multiple sellers. It exposes this through its Shop/Admin APIs. Vendure Vendure

docs.vendure.io

Saleor is another strong choice if you want GraphQL throughout. Its marketplace approach uses flexible data modeling for vendors, multi-warehouse inventory, granular permissions, apps for vendor portals/workflows, and its GraphQL API. Saleor Commerce Saleor Documentation

saleor.io

Medusa is particularly interesting for a startup because it's highly customizable. It doesn't ship with marketplace functionality as a native core feature, but its official marketplace recipe demonstrates vendor accounts, vendor-specific products/orders, custom API routes, authentication, and splitting a customer's order into vendor-specific orders. Medusa Documentation Medusa Documentation

docs.medusajs.com

If you want marketplace functionality rather than a commerce engine that you turn into one, look seriously at Mirakl. Its Marketplace Platform has dedicated Front, Operator, and Seller REST APIs covering offers, orders, seller operations, etc., and it handles things like seller management, order routing, commissions and payouts. Mirakl Developer Portal Mirakl

developer.mirakl.com

Marketplacer is similar conceptually: it's marketplace-first and can sit behind an existing/custom storefront through APIs and webhooks, handling seller onboarding, product ingestion, marketplace logic and payouts. Marketplacer Marketplacer

marketplacer.com

What I'd choose

For a new digital marketplace, my shortlist would be:

1. Vendure — best balance of headless commerce + genuine multi-vendor architecture.
2. Medusa — best if your engineering team wants maximum control and is comfortable implementing marketplace-specific logic.
3. Saleor — excellent if GraphQL and a highly composable architecture are priorities.
4. Mirakl — best if you're building a serious enterprise marketplace and don't want to implement seller operations, commissions, order routing, etc. yourself.
5. Marketplacer — good if marketplace functionality is more important than owning the underlying commerce engine.

One important distinction: “supports multiple sellers” can mean very different things. Before choosing, I'd specifically evaluate whether you need seller onboarding, seller-specific catalogs, multi-seller carts, order splitting, commissions, seller payouts, seller permissions, fulfillment, returns, and tax handling. That's where a platform like Vendure/Medusa differs substantially from a conventional headless commerce platform with a few custom vendor fields.

If you tell me your business model (physical products, digital products, services, or mixed), expected seller count, and whether you need Stripe Connect-style split payouts, I can narrow this to the 2–3 best architectures.

Marketplacer is similar conceptually: it's marketplace-first and can sit behind an existing/custom storefront through APIs and webhooks, handling seller onboarding, product ingestion, marketplace logic and payouts.

Yes. If multi-seller marketplace behavior is a core requirement, I’d narrow the field considerably. The strongest API/headless options are:

1. Vendure — probably my first choice for a custom marketplace

Vendure has explicit multi-vendor marketplace documentation rather than merely saying "you can customize it." Its marketplace pattern uses Sellers + Channels, with each seller associated with a channel, and demonstrates seller registration, seller-specific products/orders, and multi-vendor orders. Vendure Developer Hub GitHub

It's also genuinely headless: its storefront functionality is exposed through a GraphQL Shop API, alongside an Admin API. Vendure Developer Hub Vendure Developer Hub

Good if you need:

• Seller accounts and permissions
• Seller-specific catalogs
• Multi-vendor carts/orders
• Seller-specific fulfillment
• Custom commissions/platform fees
• Your own frontend and seller portal
• Full control over the data model

Caveat: Some marketplace functionality is implemented through Vendure's plugin/customization architecture rather than being a turnkey marketplace SaaS.

2. Saleor — excellent API-first option

Saleor explicitly has a marketplace recipe. Its architecture gives you flexible data modeling, vendor-specific warehouses/inventory, granular permissions, apps for vendor portals and workflows, and a GraphQL API. Saleor Documentation Saleor Commerce

This is particularly attractive if your marketplace is not a conventional Amazon clone and you expect unusual seller/product/fulfillment relationships.

Good if you need:

• GraphQL-first architecture
• Custom vendor relationships
• Vendor-specific inventory
• Custom seller dashboards
• Complex product metadata
• Custom payment/commission logic

Saleor's marketplace approach is more "here are powerful primitives for building your marketplace" than a turnkey marketplace engine.

3. Medusa — very flexible, but more DIY

Medusa has an explicit marketplace recipe, but importantly, its own documentation says marketplace functionality isn't native. Instead, you create a marketplace module with vendors, link vendors to products/orders, expose vendor API routes, and customize checkout/order workflows to split orders by vendor. Medusa Documentation Medusa Documentation

That can actually be an advantage if your marketplace model is unusual.

Medusa's Store API is REST-based, which can be attractive if your frontend/mobile clients prefer conventional REST APIs. Medusa Documentation

I'd choose Medusa if: you have a strong engineering team and want the commerce engine to be a customizable foundation rather than buying a marketplace product.

4. Mirakl — strongest marketplace-native choice

Mirakl is different from the three above. It's fundamentally designed around marketplaces rather than being a general commerce engine that you extend into one.

Its platform has dedicated Front APIs, Operator APIs and Seller APIs, covering marketplace interactions such as offers, orders, incidents and seller operations. Mirakl Developer Portal

It also handles things you'd otherwise have to engineer yourself: seller onboarding, catalog ingestion, order routing, commissions, payouts, KYC and seller performance management. Mirakl

I'd strongly consider Mirakl if:

• You expect hundreds/thousands of sellers
• Seller onboarding is important
• Sellers need sophisticated operational tooling
• You need marketplace-specific order routing
• Commissions/payouts are complicated
• You're building a serious B2B/B2C marketplace rather than a small multi-vendor store

The tradeoff is that it's generally a much heavier enterprise platform than Vendure/Saleor/Medusa.

My shortlist

For a new digital marketplace, I'd rank them roughly:

If you're engineering the product yourself:

1. Vendure — best balance of headless commerce + marketplace architecture
2. Saleor — excellent if GraphQL/API-first and custom modeling are priorities
3. Medusa — excellent flexibility, but expect more marketplace engineering
4. Mirakl — best if you want marketplace infrastructure rather than a commerce framework

One important distinction: "multi-vendor" isn't just multiple seller catalogs. I'd evaluate each platform against your actual marketplace flow:

Seller onboarding → seller catalog → product approval → inventory → buyer cart → multi-seller checkout → order splitting → fulfillment → commissions → seller payouts → refunds/returns → seller permissions

If you tell me what you're selling (physical goods, digital products, services, or B2B) and roughly how many sellers you expect in year 1, I can narrow this to the 2–3 architectures I'd seriously consider.

I'd strongly consider Mirakl if:

Yes. For a multi-seller digital marketplace, I’d shortlist these first:

My pick: Vendure

For your specific requirement—one marketplace, many independent sellers, all exposed through APIs—Vendure is probably the most directly aligned.

Vendure explicitly documents a multi-vendor marketplace architecture. Its Channels can represent individual sellers, with seller-specific products, inventory, roles and orders. Its marketplace implementation also addresses the difficult pieces such as splitting orders between sellers, shipping, payments and platform fees. Vendure Vendure Vendure

Its headless architecture exposes both a GraphQL Shop API and Admin API, so you can put your own web/mobile frontend and seller portal on top. Vendure Vendure

docs.vendure.io

When I'd choose the others

Saleor is particularly interesting if you want a highly composable GraphQL platform. Saleor now has an explicit marketplace recipe: vendors can be modeled with attributes/metadata, vendor inventory can be separated through warehouses, permissions can restrict vendor access, and apps can provide vendor portals and commission workflows. Saleor Commerce Saleor Documentation

saleor.io

Medusa is a good choice if your engineering team wants a very customizable Node/TypeScript platform and is comfortable implementing marketplace-specific domain logic. Its documentation has a marketplace recipe covering vendor management, vendor admins, vendor products/orders, and splitting a customer's order into separate vendor orders. Medusa Documentation Medusa Documentation Its Store API is REST-based. Medusa Documentation

docs.medusajs.com

One important distinction

I'd separate "headless commerce that can be customized into a marketplace" from "headless commerce with marketplace concepts already modeled."

If you need things like:

• Seller onboarding
• Seller-specific catalogs
• Seller permissions/portals
• One cart containing products from multiple sellers
• Order splitting
• Seller-specific fulfillment
• Marketplace commission/platform fees
• Seller payouts
• Refunds involving multiple sellers
• Seller-level inventory

then Vendure is the one I'd investigate first. Medusa and Saleor can absolutely support the architecture, but more of the marketplace domain is something you assemble yourself. Vendure Medusa Documentation Saleor Commerce

If you tell me whether your marketplace is digital goods (downloads/licenses), physical goods, services, or a mix, I can narrow this to 2–3 platforms and compare seller onboarding, commissions/payouts, order splitting, API quality, hosting, and estimated implementation effort.

Its headless architecture exposes both a GraphQL Shop API and Admin API, so you can put your own web/mobile frontend and seller portal on top. Vendure Vendure

Medusa is a good choice if your engineering team wants a very customizable Node/TypeScript platform and is comfortable implementing marketplace-specific domain logic. Its documentation has a marketplace recipe covering vendor management, vendor admins, vendor products/orders, and splitting a customer's order into separate vendor orders. Its Store API is REST-based.

Yes. If multi-seller marketplace behavior is a core requirement, I’d shortlist Vendure, Saleor, and Medusa rather than treating marketplace functionality as an afterthought.

1. Vendure — my first choice

Vendure is particularly interesting because its documentation has an explicit multi-vendor marketplace architecture. Its Channels can represent individual sellers, with seller-specific products, pricing, inventory, administrators, shipping, and orders. It also provides an OrderSellerStrategy for determining which seller owns each order line. Vendure Vendure

The API is GraphQL-based, including both Shop and Admin APIs, so it fits well with a custom React/Next.js storefront. Vendure

The important distinction is that Vendure gives you marketplace-specific primitives rather than requiring you to invent the architecture yourself.

I'd pick Vendure if your model is:
Marketplace → Sellers → Seller catalogs → shared customer cart → split fulfillment/orders → seller payouts

2. Saleor — very compelling alternative

Saleor explicitly documents a marketplace recipe. Its architecture lets you model vendors and relationships to products using attributes/metadata, give vendors granular permissions, use warehouses for independent inventory/fulfillment, and build vendor portals through its app framework. Its GraphQL API is the central integration layer. Saleor Documentation Saleor Commerce

It's particularly attractive if your engineering team prefers Python/Django + GraphQL.

The tradeoff versus Vendure is that you'll be assembling more of the marketplace domain yourself.

3. Medusa — excellent if you want to own the architecture

Medusa is very flexible, but marketplace functionality isn't native. Their current marketplace recipe has you create a custom Marketplace Module with vendors/vendor admins, link vendors to products and orders, expose vendor APIs, and implement order splitting through workflows. Medusa Docs Medusa Docs

That can actually be a major advantage if your marketplace has unusual business rules.

For example, if you need:

• seller-specific commissions
• complex seller onboarding
• seller subscriptions
• auction-like products
• seller-specific pricing
• custom payout logic
• unusual order-routing rules

Medusa gives you a lot of freedom to model those yourself.

What I'd choose

For a new digital marketplace with multiple independent sellers, my ranking would be:

1. Vendure — best marketplace-oriented foundation
2. Saleor — best GraphQL/Python alternative
3. Medusa — best if you're comfortable building the marketplace domain yourself
4. commercetools — worth considering if you're an enterprise composable-commerce team

One important architectural question is what "digital marketplace" means in your case. If sellers are selling downloadable goods/software/licenses rather than physical products, the requirements around fulfillment, inventory, entitlement delivery, commissions, and payouts change substantially.

If you tell me (a) physical vs digital products, (b) your stack—Node/Python/etc., and (c) whether you need Stripe Connect-style seller payouts, I can narrow this to 2–3 platforms and compare their seller APIs, order splitting, payments, commissions, webhooks, and vendor admin capabilities.

2. Saleor — very compelling alternative

Saleor explicitly documents a marketplace recipe. Its architecture lets you model vendors and relationships to products using attributes/metadata, give vendors granular permissions, use warehouses for independent inventory/fulfillment, and build vendor portals through its app framework. Its GraphQL API is the central integration layer. docs.saleor.io saleor.io

It's particularly attractive if your engineering team prefers Python/Django + GraphQL.

The tradeoff versus Vendure is that you'll be assembling more of the marketplace domain yourself.

3. Medusa — excellent if you want to own the architecture

Medusa is very flexible, but marketplace functionality isn't native. Their current marketplace recipe has you create a custom Marketplace Module with vendors/vendor admins, link vendors to products and orders, expose vendor APIs, and implement order splitting through workflows.

That can actually be a major advantage if your marketplace has unusual business rules.

For example, if you need:

Yes. The key distinction is whether you want a true marketplace engine or a headless commerce platform that you customize into one.

My shortlist

1. Mirakl — best if the marketplace itself is the core product

Mirakl is purpose-built around marketplace operations rather than merely providing ecommerce primitives. Its Marketplace Platform exposes separate Front, Operator, and Seller APIs, covering things like offers, orders, seller operations, and marketplace interactions. Mirakl Developer Portal

That makes it particularly attractive if you need:

• Seller onboarding and seller accounts
• Seller catalogs/offers
• Commission/fee structures
• Seller-specific order management
• Marketplace order workflows
• Seller APIs
• Enterprise-scale marketplace operations

The downside is that it's considerably more enterprise-oriented than something like Medusa.

2. Medusa — probably the most interesting startup option

Medusa is particularly compelling if you have engineers and want control over your marketplace data model.

Its documentation now has an explicit marketplace implementation showing how to create vendors and vendor admins, associate products with vendors, expose vendor APIs, authenticate sellers, and split a customer's order into separate vendor orders. Medusa Docs Medusa Docs

Importantly, though, marketplace functionality isn't native: Medusa explicitly describes this as something you build using its customization framework, modules, links, API routes, and workflows. Medusa Docs

That can actually be an advantage if your marketplace has unusual rules.

3. commercetools + Mirakl — strongest enterprise composable architecture

commercetools gives you the headless commerce layer while Mirakl supplies the marketplace capabilities. There's an established integration between the two specifically designed around a headless approach. Commercetools Marketplace

I'd consider this if you expect substantial scale and want to keep catalog, pricing, cart, checkout, etc. composable rather than putting everything inside a marketplace monolith.

What I'd choose

For a new digital marketplace with multiple independent sellers, I'd narrow it to:

• Mirakl → if you want marketplace functionality largely out of the box and have an enterprise budget.
• Medusa → if you're a startup with a strong engineering team and want maximum control/customization.
• commercetools + Mirakl → if you're building an enterprise-grade composable architecture.

One particularly important question is what "digital marketplace" means in your case. If sellers are selling digital goods (courses, downloads, SaaS, tickets, licenses, etc.), rather than physical products, the ideal architecture changes substantially—especially around fulfillment, entitlements, seller payouts, and order splitting.

If you tell me (1) physical vs digital goods, (2) expected seller count, (3) B2B/B2C, and (4) whether you need Stripe Connect-style seller payouts, I can narrow this to the 2–3 best platforms and compare their APIs/architecture.

That can actually be an advantage if your marketplace has unusual rules.

3. commercetools + Mirakl — strongest enterprise composable architecture

commercetools gives you the headless commerce layer while Mirakl supplies the marketplace capabilities. There's an established integration between the two specifically designed around a headless approach.

I'd consider this if you expect substantial scale and want to keep catalog, pricing, cart, checkout, etc. composable rather than putting everything inside a marketplace monolith.

What I'd choose

For a new digital marketplace with multiple independent sellers, I'd narrow it to:

Yes. For a multi-seller digital marketplace, I’d shortlist Medusa and Saleor first, with an important distinction: neither is simply a turnkey “Amazon clone” out of the box; marketplace concepts are implemented through their APIs/extensibility.

1. Medusa — probably my first choice

Medusa has an explicit marketplace architecture/recipe. You can create a custom vendor module, associate vendors with products and orders, expose seller-specific API routes, authenticate vendor admins, and implement workflows that split a customer's order into separate vendor orders. docs.medusajs.comgithub.com

It also has REST Store APIs, which makes it straightforward to put your own web/mobile frontend or BFF on top. docs.medusajs.com

There's additionally a marketplace starter/ecosystem around Medusa with features such as vendor dashboards, commissions, vendor verification, unified checkout, and split payments/payouts. medusajs.com

Why I'd consider it: if your marketplace has unusual business rules—seller-specific pricing, commissions, digital fulfillment, seller permissions, custom payout logic, etc.—Medusa gives you a fairly clean programmable commerce backend.

2. Saleor — excellent if you're GraphQL-first

Saleor has an explicit marketplace solution. Its approach uses attributes/metadata for seller modeling, warehouses for seller-specific inventory/fulfillment, granular permissions, apps for seller portals and workflows, and its GraphQL API as the underlying interface. saleor.io

For a digital marketplace, its API-first architecture is particularly attractive if you're building your own seller dashboard and customer experience rather than adopting a prebuilt storefront. Saleor is GraphQL-native and API-only/headless. github.com

The key architectural question

For your use case, I'd evaluate whether you need:

Customer
→ browse products from many sellers
→ single cart
→ single checkout
→ payment
→ order gets allocated to sellers

Seller
→ onboarding/KYC
→ own catalog
→ inventory/license availability
→ own orders
→ earnings/commissions
→ fulfillment/digital delivery

Marketplace operator
→ seller approval
→ commissions
→ refunds/disputes
→ payouts
→ analytics

The seller → product → order → payout relationships are the part that distinguishes a real marketplace from ordinary headless commerce.

My recommendation

If you're building this from scratch today:

Choose Medusa if: you want REST, TypeScript, maximum customization, and relatively straightforward custom marketplace domain logic.

Choose Saleor if: your engineering team likes GraphQL and you want a very API-centric architecture with permissions/apps as the extension mechanism.

For a digital-goods marketplace specifically, I'd lean Medusa if you expect substantial custom seller/payment/order logic. Its marketplace recipe explicitly demonstrates vendor-specific products, vendor authentication, vendor orders, and order splitting. docs.medusajs.com

If you tell me your marketplace model (e.g. Etsy-style digital downloads, app/plugin marketplace, course marketplace, or services marketplace), I can compare Medusa vs Saleor vs commercetools vs Mirakl specifically around seller onboarding, Stripe Connect/payouts, commissions, split orders, digital fulfillment, and API flexibility.

For a multi-seller digital marketplace (think Etsy/Amazon-style: sellers, seller catalogs, commissions, split orders, vendor dashboards, payouts), you’ll want a headless commerce platform that exposes strong APIs and lets you extend the commerce model. The best fits are usually:

1. Medusa — probably the most flexible for a custom marketplace

Medusa is a good choice if your marketplace logic is unique (seller onboarding, commissions, custom fulfillment, revenue sharing). It does not force a marketplace model, but provides a framework where you can add vendors, seller permissions, seller products, and split orders through custom modules and APIs. docs.medusajs.com

Typical architecture:

• Seller entity/module
• Seller admin authentication
• Seller product ownership
• Cart containing products from multiple sellers
• Order splitting by seller
• Commission calculation service
• Payout integration (e.g., Stripe Connect)

Good fit if you have engineers and want ownership of your marketplace rules.

2. Saleor — strong API-first marketplace foundation

Saleor is built around GraphQL and has marketplace guidance covering vendor modeling, permissions, inventory separation, vendor portals, and custom workflows. docs.saleor.iosaleor.iodocs.medusajs.com

Strengths:

• Native GraphQL API
• Flexible data modeling
• Permissions for seller roles
• Multi-warehouse inventory (useful for seller-specific fulfillment)
• App framework for seller dashboards and integrations docs.saleor.iosaleor.iodocs.medusajs.com

Good fit if you want a highly composable architecture.

3. Vendure — excellent for TypeScript teams

Vendure is another API-first option built on NestJS/TypeScript. It is often attractive if your team wants to customize the core commerce engine rather than assemble many external services. headlesscommerceplatforms.com

4. Enterprise options

For large-scale marketplaces:

• commercetools — powerful APIs, but you’ll build more marketplace-specific functionality yourself.
• Adobe Commerce — mature ecosystem, but less “pure headless” architecturally.

Marketplace capabilities to verify before choosing

Make sure the platform can handle:

Seller management

• Seller accounts and permissions
• Seller-specific dashboards
• Seller onboarding workflows

Catalog

• Seller-owned products
• Product approval workflows
• Seller-specific pricing

Checkout

• Multi-vendor carts
• Split shipments
• Split commissions
• Tax handling

Orders

• Parent order → child seller orders
• Seller fulfillment status
• Returns/refunds per seller

Payments

• Marketplace payouts
• Commission deductions
• Escrow-like flows

APIs

• Storefront API
• Admin API
• Webhooks/events
• Custom entities/modules

My shortlist by scenario

• You are building a differentiated marketplace: Medusa or Vendure
• You want GraphQL + composable architecture: Saleor
• You expect enterprise scale: commercetools
• You want fastest MVP: Shopify + marketplace extensions (with tradeoffs)

For a new marketplace startup, I’d usually evaluate Medusa vs Saleor first because both let you avoid fighting a monolithic commerce model while still giving you core commerce primitives. docs.saleor.iosaleor.iodocs.medusajs.com

A key decision point: are your sellers selling physical goods, digital products, or a service/booking marketplace? The best architecture changes quite a bit depending on that.

Yes. If your defining requirement is “multiple independent sellers, but I want a headless/API-first commerce engine underneath my own marketplace UX,” there are a few particularly strong options.

My shortlist

1. Vendure — probably the first one I'd evaluate

Vendure explicitly supports multi-vendor marketplace patterns: sellers can own products, customers can put products from multiple sellers into one order, and the platform provides APIs around seller-specific order handling, shipping, payments and platform fees. Vendure even provides a reference marketplace implementation. Vendure Developer Hub Vendure

That makes it unusually close to your use case without forcing you to build the marketplace primitives entirely yourself.

docs.vendure.io

2. Saleor — excellent if GraphQL is important

Saleor is API-only/headless and has a specific marketplace architecture. Its marketplace approach uses vendors, permissions, metadata/custom relationships, vendor-specific warehouses, apps/vendor portals and payment splitting. Saleor Commerce Saleor Commerce

This is attractive if your architecture looks like:

Next.js / mobile apps → GraphQL → Saleor → payments / fulfillment / seller systems

saleor.io

3. Medusa — excellent for a TypeScript-heavy team

Medusa is very flexible, but its marketplace functionality is more of a build-on-the-commerce-engine approach than Vendure's marketplace-specific primitives. Its official marketplace recipe shows how to model vendors, authenticate vendor users and split a customer's order into separate vendor orders using workflows. Medusa Docs

I'd seriously consider it if your engineering team is already heavily invested in Node/TypeScript and you want marketplace business logic to be yours rather than dictated by the platform.

docs.medusajs.com

4. Mirakl — consider this if you want marketplace infrastructure rather than a commerce engine

Mirakl is different from the three above: it's specifically a marketplace platform, rather than primarily a headless commerce engine that you customize into one. Its APIs cover marketplace operations, sellers, catalogs, orders, etc., and it has integrations with commerce platforms including commercetools. Mirakl Developer Portal Commercetools Marketplace

I'd look at Mirakl if you're targeting a fairly sophisticated marketplace from day one and don't want to implement seller onboarding, marketplace operations, commissions, etc. yourself.

What I'd choose

For a new digital marketplace, I'd narrow it to:

• Vendure → best if marketplace functionality is central to the product.
• Saleor → best if you want a very clean GraphQL/API-first architecture.
• Medusa → best if you want a highly customizable TypeScript platform and are comfortable implementing marketplace-specific logic.
• Mirakl → best if you're building an enterprise-scale marketplace and are willing to pay for a specialized marketplace platform.

The important distinction is that “supports multiple sellers” isn't enough. I'd specifically evaluate how each handles:

• Seller onboarding/KYC
• Seller-specific catalogs and permissions
• One cart containing products from multiple sellers
• Order splitting
• Seller-specific fulfillment/shipping
• Marketplace commissions
• Split payments / seller payouts
• Refunds and partial refunds
• Seller returns
• Seller dashboards
• Inventory ownership
• Taxes
• Webhooks/events
• Seller API access
• Multi-currency
• Digital-product fulfillment, if that's what you're selling

For a digital marketplace, I'd pay particular attention to payouts, entitlements, refunds and seller permissions—those tend to become much harder than the product catalog itself.

If you tell me your expected seller count, whether sellers set their own prices, whether products are digital/physical, and what payment provider you're considering (e.g. Stripe Connect), I can narrow this to the 2–3 architectures I'd actually shortlist.

2. Saleor — excellent if GraphQL is important

Saleor is API-only/headless and has a specific marketplace architecture. Its marketplace approach uses vendors, permissions, metadata/custom relationships, vendor-specific warehouses, apps/vendor portals and payment splitting. Saleor Commerce Saleor Commerce

This is attractive if your architecture looks like:

Next.js / mobile apps → GraphQL → Saleor → payments / fulfillment / seller systems

3. Medusa — excellent for a TypeScript-heavy team

Medusa is very flexible, but its marketplace functionality is more of a build-on-the-commerce-engine approach than Vendure's marketplace-specific primitives. Its official marketplace recipe shows how to model vendors, authenticate vendor users and split a customer's order into separate vendor orders using workflows. docs.medusajs.com

I'd seriously consider it if your engineering team is already heavily invested in Node/TypeScript and you want marketplace business logic to be yours rather than dictated by the platform.

docs.medusajs.com

4. Mirakl — consider this if you want marketplace infrastructure rather than a commerce engine

Mirakl is different from the three above: it's specifically a marketplace platform, rather than primarily a headless commerce engine that you customize into one. Its APIs cover marketplace operations, sellers, catalogs, orders, etc., and it has integrations with commerce platforms including commercetools.

Yes. For a multi-seller marketplace where you want a headless/API-first backend, I’d shortlist these:

My picks

For a startup: I'd look hardest at Medusa. Its marketplace architecture explicitly models vendors, associates vendors with products/orders, gives vendors their own authenticated API routes, and demonstrates splitting a customer's cart/order across vendors. docs.medusajs.com

For a GraphQL-first product: Saleor is compelling. Its current marketplace approach uses attributes/metadata for vendor relationships, warehouses for independent inventory/fulfillment, granular permissions, apps for vendor portals and commissions, and GraphQL for the marketplace API. saleor.io

For enterprise/composable commerce: commercetools is the stronger infrastructure choice if you're prepared to build the marketplace layer yourself. Its APIs expose products, customers, carts, orders, etc. as resources and support both REST and GraphQL. docs.commercetools.com

One important distinction: "supports marketplaces" can mean either native multi-vendor functionality or "provides enough APIs/extensibility to build one." Medusa and Saleor are primarily in the latter camp—their marketplace implementations require you to build parts such as seller onboarding, vendor portals, commissions/payouts, and seller-specific permissions/workflows. Saleor explicitly describes its marketplace solution as customizable rather than a turnkey marketplace engine. saleor.io

If you tell me your seller count, whether sellers fulfill their own orders, commission/payout model, and preferred stack (Node/Python/etc.), I can narrow this to the best 2–3 and compare their APIs/data models for seller → product → inventory → order split → payout.

Yes. If multi-seller marketplace behavior is a core requirement, I’d narrow the field considerably. The strongest API/headless options today are:

1. Vendure — my top pick

Vendure is particularly interesting because marketplace concepts are built into its architecture. Its Channels can represent sellers, and its marketplace APIs/reference implementation address things like seller-specific products, order splitting, fulfillment, payments and platform fees. docs.vendure.iovendure.io

Its Shop API is GraphQL, so you can put essentially any frontend or seller portal on top of it. docs.vendure.io

I'd choose it if: each seller needs their own catalog, inventory, orders, fulfillment, permissions, etc., and you expect the marketplace logic to get sophisticated.

2. Saleor

Saleor now has an explicit marketplace architecture/recipe. You can model vendors with attributes and metadata, use warehouses for seller-specific inventory/fulfillment, apply granular permissions, and build seller portals as apps around its GraphQL API. saleor.io

It's particularly attractive if you want a very API-centric, composable architecture and are comfortable implementing some marketplace business logic yourself.

3. Medusa

Medusa is excellent if you're building a custom product rather than expecting the commerce platform to dictate your marketplace architecture.

Its official marketplace recipe demonstrates:

• multiple vendors
• vendor administrators
• vendor-specific products/orders
• splitting a customer's order into vendor orders
• custom vendor APIs and workflows docs.medusajs.comvendure.io

Medusa v2 exposes REST Store APIs, and its framework is designed to be extended with custom modules, API routes and workflows. docs.medusajs.com

There's also a marketplace starter with vendor dashboards and features such as unified multi-vendor checkout and split payments/payouts. medusajs.com

I'd choose it if: your team is strongest in TypeScript/Node and you want maximum control over the marketplace domain model.

4. commercetools

commercetools is extremely API-first and supports REST and GraphQL, with flexible concepts such as Channels, Stores, Products, Carts and Orders. docs.commercetools.com

But I'd put it in a different category: enterprise composable commerce primitives rather than an immediately marketplace-oriented framework. You'd be assembling more of the seller/marketplace layer yourself.

My recommendation

For a new marketplace, I'd evaluate them in this order:

Vendure → Medusa → Saleor → commercetools

The distinction I'd make is:

• Want marketplace functionality closest to the platform's core? → Vendure
• Want maximum TypeScript customization? → Medusa
• Want GraphQL/API-first + highly composable architecture? → Saleor
• Have a large enterprise engineering organization? → commercetools

One important architectural question is how money flows. If you're taking a marketplace commission and paying sellers out, make sure you evaluate seller onboarding/KYC, split payments, refunds, chargebacks, tax, seller-specific fulfillment, and order splitting separately from merely "multi-vendor product catalogs." Vendure explicitly addresses several of these marketplace concerns; Saleor and Medusa give you extensibility to implement them. vendure.io

If you tell me (1) physical vs digital goods, (2) expected seller count, (3) whether sellers receive payouts directly, and (4) your frontend stack, I can narrow this to the best 2–3 and compare their APIs/data models specifically for your marketplace.

Yes. If multi-seller marketplace behavior is a core requirement, I’d shortlist these rather than generic headless commerce platforms:

My take

1. Vendure — probably the best starting point for a new marketplace.

Vendure explicitly documents multi-vendor marketplace architecture. Its model uses Sellers + Channels, and it supports customers placing orders containing products from multiple sellers. The marketplace functionality is exposed through its GraphQL APIs and can be extended with plugins. docs.vendure.io

Vendure marketplace documentation

2. Mirakl — best if you're building a marketplace first and commerce second.

Mirakl is much more marketplace-native than the others. Its Marketplace Platform has separate Front, Operator, and Seller APIs, covering things like offers, orders, seller operations and marketplace workflows. developer.mirakl.com

It's particularly compelling if you need sophisticated seller onboarding, catalog ingestion, seller operations, commissions/marketplace economics, and enterprise-scale marketplace management. mirakl.com

Mirakl Developer Portal

3. Saleor — excellent API-first option.

Saleor doesn't give you a turnkey "seller marketplace" in quite the same way as Mirakl, but its architecture is very well suited to building one. It specifically recommends modeling vendors, using vendor-specific warehouses, granular permissions, custom apps, and Stripe Connect for payment splitting. Everything can be driven through its GraphQL API. saleor.io

Saleor marketplace architecture

4. Medusa — great if your engineering team wants to own the marketplace logic.

Medusa explicitly has a marketplace recipe, but importantly, marketplace functionality isn't native. You create a vendor module, link vendors to products/orders, create vendor APIs, and implement order splitting yourself. docs.medusajs.com

Medusa marketplace documentation

The key distinction

I'd divide them like this:

Want the marketplace to be the product:
→ Mirakl

Want an open-source/headless commerce engine with good marketplace primitives:
→ Vendure

Want GraphQL + highly composable architecture:
→ Saleor

Want maximum control and have a strong engineering team:
→ Medusa

For a marketplace where each seller has their own catalog, inventory, orders, fulfillment, permissions, and payouts, I'd personally investigate Vendure vs. Mirakl first. The biggest architectural question is whether you want to extend a commerce platform into a marketplace (Vendure) or use a platform designed around marketplace operations (Mirakl).

If you tell me your seller model (physical/digital), expected seller count, payment provider, and whether sellers need their own dashboards, I can narrow this to 2–3 platforms and compare their APIs, order splitting, payouts, seller onboarding, and pricing.

Yes. For a multi-seller digital marketplace, I’d narrow the field to four serious options:

My recommendation

If you're building a marketplace rather than just adding marketplace functionality to a store, I'd start with Vendure, Saleor, and Mirakl.

Vendure is particularly interesting because its architecture explicitly models sellers through Channels, and its documentation has a multi-vendor implementation covering seller registration, seller-specific products, and orders containing products from multiple sellers. docs.vendure.io

Saleor is similarly compelling if you want a very API-centric architecture. Its marketplace approach uses custom vendor relationships, vendor-specific warehouses, granular permissions, apps for seller portals/commissions, and GraphQL throughout. saleor.io

Medusa is more of a "commerce engine you extend into a marketplace." Its official recipe has you create vendor data models, vendor API routes, and workflows that split a customer's order into separate vendor orders. That's powerful, but more engineering work than Vendure/Saleor's marketplace-oriented building blocks. docs.medusajs.com

Mirakl is different: it is fundamentally a marketplace platform rather than a conventional headless commerce engine. Its APIs cover offers, orders, shops, seller operations, incidents, etc., with separate Front, Operator, and Seller APIs, plus GraphQL. docs.vendure.iosaleor.iodeveloper.mirakl.commirakl.com If you need sophisticated seller onboarding, catalog ingestion, seller operations, and enterprise marketplace workflows, it's probably the strongest option. mirakl.com

One important distinction

I'd decide based on how much marketplace infrastructure you want to own:

• "Give me a commerce engine and I'll build the marketplace" → Medusa
• "Give me a customizable commerce engine with marketplace primitives" → Vendure
• "Give me an API-first commerce platform I can model into a marketplace" → Saleor
• "Give me a mature marketplace operating system" → Mirakl

For your use case, I'd pay particular attention to seller onboarding, seller permissions, catalog ownership, multi-seller carts, order splitting, commissions, payouts, fulfillment, and seller APIs. Those are much more important than simply having a "headless" storefront API.

If you tell me your stack (e.g. Next.js), expected seller count, B2C vs B2B, and whether you need Stripe Connect/payouts, I can narrow this to the best 1–2 choices and compare their APIs/architecture.

Yes. If multi-seller marketplace behavior is a core requirement, I’d narrow the field considerably. There’s a big difference between a headless commerce engine that can be customized into a marketplace and one that has marketplace workflows built in.

1. Mirakl — strongest marketplace-first choice

Mirakl is probably the first platform I'd evaluate if your marketplace itself is the product.

Its Marketplace Platform exposes separate Front, Operator, and Seller APIs, covering things such as offers, orders, seller operations, ratings, incidents, and marketplace management. developer.mirakl.com

That means you aren't trying to bolt a seller model onto a normal ecommerce engine. The architecture already assumes:

Marketplace → Sellers → Offers/catalog → Orders → Fulfillment

This is particularly attractive if you need seller onboarding, seller portals, commissions, catalog ingestion, seller-specific operations, etc.

2. VTEX — excellent if you want commerce + marketplace together

VTEX has a dedicated Marketplace API with seller registration, seller invitations, seller commissions, SKU suggestions, offer matching, seller accounts, and sales-channel mapping. developers.vtex.com

It also explicitly supports external sellers, so sellers don't necessarily need to run their stores on VTEX. Its Marketplace Protocol covers fulfillment simulation, order placement, cancellations, invoices and tracking between marketplace and sellers. developers.vtex.com

This is a particularly good fit if you're building something closer to Amazon/eBay-style marketplace infrastructure, but want a mature commerce stack around it.

3. Medusa — best if you're a developer-heavy startup

Medusa is interesting because it explicitly documents how to build a marketplace.

The important caveat: marketplace functionality isn't native out of the box. Instead, Medusa gives you the framework to create vendors, vendor admins, vendor-product relationships, vendor APIs, and vendor-specific order handling. docs.medusajs.com

Their documented marketplace implementation includes:

• multiple vendors
• vendor admins/authentication
• vendors managing their own products
• vendor-specific APIs
• splitting a customer's order by vendor
• vendor-specific order management
• custom seller dashboards

docs.medusajs.com

The APIs are REST-based, and Medusa explicitly supports custom API routes, making it quite suitable for a custom frontend/mobile app. docs.medusajs.com

Medusa marketplace documentation

4. Saleor — worth serious consideration

Saleor is API-first and GraphQL-based, and its documentation now has an explicit Marketplace recipe. docs.saleor.io

I'd consider it if your engineering team strongly prefers GraphQL and wants a composable/headless architecture rather than buying a marketplace-specific SaaS platform.

Saleor documentation

5. commercetools — powerful, but more DIY

commercetools is extremely API-centric and designed to sit behind custom storefronts and other systems. docs.commercetools.com

But I wouldn't choose it because you need a marketplace. You'd be designing more of the marketplace domain yourself—seller entities, seller permissions, offer relationships, order splitting, seller payouts, etc.

What I'd shortlist for your situation

If you're launching a new marketplace, my order would be:

Mirakl → VTEX → Medusa → Saleor → commercetools

But there's an important fork:

• You want marketplace functionality out of the box: Mirakl
• You want enterprise commerce + marketplace: VTEX
• You want to own the architecture and customize heavily: Medusa
• You want GraphQL/API-first and engineering flexibility: Saleor
• You already have a sophisticated composable-commerce team: commercetools

For a startup, I'd look particularly hard at Medusa vs. Mirakl. Medusa gives you considerably more control and potentially a lower-level foundation, whereas Mirakl gives you much more of the difficult marketplace machinery—seller operations, offers, marketplace APIs, etc.—already modeled.

If you tell me (1) physical vs digital goods, (2) expected number of sellers, (3) whether you need seller payouts/commissions, and (4) your frontend/backend stack, I can narrow this to the 2–3 platforms I'd actually shortlist and compare their API architecture, pricing model, seller onboarding, order splitting, and Stripe/payment integration.

Yes. For a multi-seller marketplace where the commerce backend is headless and API-driven, I’d shortlist these:

1. Vendure — my first choice

Vendure is unusually well aligned with your requirement. Its documentation has a dedicated multi-vendor marketplace architecture, where sellers are represented through Sellers + Channels, and customers can place orders containing products from multiple sellers. It exposes the functionality through its GraphQL APIs. docs.vendure.io

This makes it a particularly good fit if you need:

• seller accounts and permissions
• seller-specific catalogs
• seller-specific inventory
• orders containing products from multiple sellers
• seller dashboards
• marketplace-specific business rules
• custom commissions/payout logic
• a completely custom frontend

The important distinction is that you're not just bolting a marketplace plugin onto a traditional ecommerce system—the platform's Channels architecture maps naturally onto sellers.

Vendure marketplace documentation

2. Saleor

Saleor is another strong option, particularly if you want a very API-centric architecture. Saleor explicitly provides a marketplace recipe using vendors, product relationships, permissions, warehouses, apps, and its GraphQL API. saleor.io

It's especially interesting if each seller needs their own:

• inventory/warehouse
• fulfillment
• permissions
• vendor portal
• product management

Saleor also has a strong extension/app architecture, which is useful for things like marketplace commissions, vendor onboarding and payout workflows. saleor.io

Saleor marketplace documentation

3. Medusa

Medusa is excellent if your engineering team is comfortable with TypeScript/Node and expects to build significant marketplace logic themselves.

Medusa explicitly documents a marketplace implementation involving multiple vendors, vendor admins, vendor-specific products/orders, and splitting a customer's order into separate vendor orders. docs.medusajs.com

The caveat: marketplace functionality isn't a fully native core feature in the same sense as Vendure's marketplace-oriented architecture. Medusa's approach is essentially commerce primitives + custom marketplace module/workflows/API routes. docs.medusajs.com

That can actually be an advantage if your marketplace model is unusual.

Medusa marketplace documentation

What I'd pick

If you're starting from scratch:

Vendure → best overall fit if marketplace is the central business model.

Medusa → best if you want a highly programmable TypeScript backend and don't mind implementing more marketplace logic.

Saleor → best if you prefer GraphQL/Python and want a polished API-first commerce foundation with marketplace extensions.

commercetools → worth serious consideration if you're building an enterprise marketplace with a large engineering organization and substantial infrastructure budget.

The key thing I'd evaluate isn't just "does it support multiple sellers?" It's whether it handles the order-splitting + inventory + fulfillment + seller permissions + commissions + payouts model you need. Those are where marketplace implementations become substantially different from ordinary headless commerce.

If you tell me (1) physical vs digital products, (2) expected number of sellers, (3) whether sellers fulfill themselves, and (4) Stripe Connect/payout requirements, I can narrow this to the best 2–3 and compare their APIs/architecture directly.

Yes. If multi-seller marketplace behavior is a core requirement, I’d narrow the field considerably. The important distinction is between a headless commerce engine that can be customized into a marketplace and one that already has marketplace primitives.

Best options

1. Mirakl — strongest marketplace-native choice

If your business is fundamentally a marketplace, this is probably the first platform I'd evaluate.

Mirakl's marketplace platform has dedicated seller APIs, operator APIs and front APIs, covering offers, products, orders, seller operations, returns, shipments, etc. developer.mirakl.com

That means you're not trying to turn a normal ecommerce data model into:

Product → Seller → Offer → Order → Seller Order → Commission → Payout

It's designed around that model.

Choose Mirakl if: you expect hundreds/thousands of sellers, complex seller onboarding, commissions, fulfillment, seller SLAs, multiple offers for the same product, etc.

Mirakl Developer Portal

2. Medusa — excellent if you want to build the marketplace yourself

Medusa is particularly interesting for a startup because its architecture is designed to be extended.

Its official marketplace recipe demonstrates:

• multiple vendors
• vendor-specific admins
• vendor product management
• vendor-specific orders
• splitting a customer's order across vendors
• custom marketplace API routes
• custom data models/workflows docs.medusajs.commedusajs.com

Medusa also now has a marketplace starter ecosystem with vendor dashboards, unified checkout, split payments/payouts, commissions, vendor verification, etc. medusajs.com

The caveat: marketplace functionality isn't the same thing as Medusa's core native commerce model. You're extending it.

Choose Medusa if: you're technical, want ownership of the marketplace domain model, and don't want to pay for a heavyweight enterprise marketplace platform from day one.

Medusa marketplace documentation

3. Saleor — strong GraphQL/API-first option

Saleor is another good fit if your team strongly prefers GraphQL.

Its marketplace architecture supports modeling vendors through attributes/metadata, vendor-specific warehouses, granular permissions, custom vendor apps and marketplace workflows through the GraphQL API. saleor.io

It's particularly attractive if you're building a custom marketplace UX rather than wanting a turnkey marketplace backend.

The downside is similar to Medusa: you'll be implementing meaningful portions of the marketplace domain yourself.

Saleor marketplace architecture

4. commercetools + Mirakl — probably the strongest enterprise architecture

If you're thinking composable commerce, pairing commercetools with Mirakl is compelling.

Mirakl supplies the marketplace-specific machinery while commercetools provides the headless commerce layer. There is an established headless integration between the two. marketplace.commercetools.com

I'd consider this if you're building something closer to Amazon Marketplace / Walmart Marketplace / a large B2B marketplace than an early-stage Etsy-style marketplace.

What I'd choose for a new marketplace

I'd make the decision this way:

Startup / MVP / highly customized product
→ Medusa

GraphQL-first engineering team
→ Saleor

Marketplace is the actual business and seller operations are complex
→ Mirakl

Large enterprise + composable architecture
→ commercetools + Mirakl

One important thing: don't evaluate these just on whether they have a "multi-vendor" checkbox. Your architecture needs to handle seller onboarding, seller identity/permissions, seller catalog ownership, offers, inventory, split carts/orders, commissions, payment splitting, payouts, refunds, returns, shipping, and seller-level fulfillment.

For a digital marketplace, I'd especially scrutinize payment splitting and payout accounting early—those tend to be much harder to retrofit than product/catalog functionality.

If you tell me what you're selling (digital products, physical goods, services, etc.), expected seller count, and whether sellers receive payouts directly, I can narrow this to 2–3 platforms and compare their APIs/data models.

Yes. If multi-seller marketplace behavior is a core requirement, I’d shortlist these rather than treating a normal headless commerce platform as a marketplace out of the box:

1. Vendure — my first choice

Vendure is unusually well suited to this use case. Its Channels + Sellers model maps naturally to sellers: each seller can have a channel, catalog/inventory, pricing, shipping configuration and restricted admin permissions. Its marketplace documentation specifically covers sellers listing products and customers placing orders containing products from multiple sellers. docs.vendure.io

It also exposes both a Shop GraphQL API and Admin GraphQL API, so you can build your own buyer marketplace UI and seller portal rather than being locked into a storefront. docs.vendure.io

Vendure marketplace documentation

Particularly good if you need:

• Seller accounts/permissions
• Seller-specific catalogs
• Seller-specific pricing
• Seller inventory/fulfillment
• Multi-seller carts
• Splitting orders by seller
• A custom seller dashboard
• Full control over marketplace logic

2. Saleor

Saleor now has an explicit marketplace architecture/recipe. It provides the underlying pieces—vendor modeling, permissions, multi-warehouse inventory, apps, and GraphQL—and expects you to compose the actual marketplace behavior. It even documents Stripe Connect-style payment splitting as part of the architecture. saleor.io

Saleor marketplace solution

I'd consider Saleor if GraphQL + Python/Django + a highly customized architecture appeals to your team.

3. Medusa

Medusa is very attractive if you're building in TypeScript/Node and want to own the marketplace business logic. It doesn't provide marketplace functionality natively, but its framework is explicitly designed to be extended for it. Its official marketplace recipe demonstrates vendor admins, vendor-owned products/orders, and splitting a customer's order into vendor-specific orders. docs.medusajs.com

Its Store API is REST-based, which can be convenient for a custom frontend/mobile application. docs.medusajs.com

Medusa marketplace documentation

My recommendation

For a new digital marketplace with multiple independent sellers, I'd rank them:

Vendure > Medusa ≈ Saleor > commercetools

The key distinction is that Vendure has marketplace concepts much closer to first-class domain objects, whereas Medusa and Saleor give you excellent primitives from which you construct the marketplace.

If your marketplace has this flow:

Seller → lists digital product → buyer → multi-seller cart → checkout → payment split → individual seller orders → seller fulfillment/download → commissions/payouts

I'd pay particular attention to order splitting, seller permissions, inventory/entitlements, and payment/payout architecture rather than just asking whether a platform has a "multi-vendor" checkbox. Payment splitting/payouts, for example, generally require Stripe Connect or another payment orchestration layer rather than being purely a commerce-platform feature. Saleor explicitly describes this as an app/custom-payment concern. saleor.io

If you tell me (1) physical vs digital products, (2) expected number of sellers, (3) Stripe/other payments, and (4) your stack (Next.js, Laravel, Django, etc.), I can narrow this to the best 2–3 options and compare their seller APIs, order splitting, commissions, payouts, permissions, and licensing/pricing.

Yes. If multi-seller marketplace behavior is a core requirement, I’d separate the options into two categories:

My top two

1. Mirakl — best if marketplace is the product

Mirakl is purpose-built around marketplace operations rather than being a conventional commerce engine that you have to turn into one. Its APIs explicitly cover operator, seller, and front-end interactions, including seller-specific operations. developer.mirakl.com

It supports things you'd typically need to build yourself: seller onboarding, offers/catalogs, multi-seller orders, shipments, seller operations, commissions/payouts and marketplace workflows. Mirakl also has a headless integration with commercetools. mirakl.commarketplace.commercetools.com

2. Medusa — best if you're engineering the marketplace yourself

Medusa is interesting if you're a startup and want the marketplace logic to be part of your own application rather than buying a full marketplace SaaS.

Its documentation has an explicit marketplace architecture showing how to implement:

• multiple vendors
• vendor authentication/admins
• vendor-specific products and orders
• splitting a customer's order across vendors
• vendor-specific API routes
• custom marketplace data models

However, the important caveat is that marketplace functionality isn't native; you're building it using Medusa's customization framework. developer.mirakl.comdocs.medusajs.com

What I'd choose

If your requirements look like:

Customer → marketplace → many independent sellers → seller onboarding → seller catalog → seller fulfillment → commissions/payouts → split orders

I'd choose Mirakl if you want the marketplace infrastructure largely solved.

I'd choose Medusa if your competitive advantage is in the marketplace experience/business logic and you have a strong engineering team willing to own the implementation.

And if you're building a sophisticated enterprise composable stack, commercetools + Mirakl is particularly compelling: commercetools handles the headless commerce layer while Mirakl handles the marketplace layer. The two have an official integration designed specifically around that headless architecture. mirakl.commarketplace.commercetools.com

If you tell me roughly seller count (e.g. 50 vs 10,000), B2B/B2C, whether sellers need their own dashboards, and whether you need marketplace payouts, I can narrow this down to the best 2–3 architectures and compare API, order splitting, seller onboarding, payments, fees, and estimated implementation complexity.

Yes. For a multi-seller marketplace where you own the platform and sellers manage their own catalog/orders, I’d shortlist these:

My top pick: Vendure

Vendure is particularly interesting because marketplace concepts are explicitly supported rather than requiring you to bolt everything onto a normal single-store commerce model.

Its Channels can represent individual sellers, with seller-specific products, prices, stock locations, shipping methods, administrators, and orders. Vendure also provides a specific multi-vendor marketplace implementation and APIs for the pattern. docs.vendure.io

The architecture is fully headless: a GraphQL Shop API handles storefront operations and an Admin API handles administration. docs.vendure.io

The particularly important part is that Vendure designed its marketplace support around problems such as splitting orders, shipping, payments, fulfillments and platform fees—the things that usually become painful when adapting a conventional ecommerce backend. vendure.io

Vendure marketplace documentation

Medusa: excellent if you want maximum control

Medusa is another strong option. Its architecture makes it straightforward to create a custom Vendor/Marketplace module, associate vendors with products and orders, expose seller-specific API routes, and implement workflows such as splitting a customer's order by vendor. docs.medusajs.com

The distinction is important: marketplace functionality isn't native in the same sense as Vendure's marketplace model. Medusa gives you the framework to build it, and provides an official marketplace recipe/example. docs.medusajs.com

Medusa's storefront APIs are REST-based, which can be attractive if you want conventional REST endpoints rather than GraphQL. docs.medusajs.com

Medusa marketplace docs

Saleor: very compelling for API-first teams

Saleor is GraphQL-native and explicitly positions itself for marketplace implementations. It provides flexible metadata/attributes for modeling vendors, multi-warehouse inventory, granular permissions, and an app framework for vendor portals and custom marketplace workflows. saleor.io

I'd choose Saleor if your architecture already revolves around GraphQL + external services/apps, rather than wanting the commerce backend itself to encode most of the marketplace logic.

Saleor marketplace documentation

What I'd choose

For your use case, I'd rank them:

1. Vendure — best if marketplace behavior is core to the business
2. Medusa — best if you expect substantial custom business logic
3. Saleor — best if you're building a highly composable GraphQL architecture
4. Sylius — worth considering if your team is heavily invested in PHP/Symfony

One thing I'd evaluate before choosing the platform is whether you need:

• seller onboarding/KYC
• seller-specific catalogs
• seller dashboards
• one cart containing products from multiple sellers
• automatic order splitting
• seller-specific fulfillment/shipping
• commissions/platform fees
• Stripe Connect-style split payments and payouts
• refunds/partial refunds across sellers
• seller API credentials/webhooks
• seller-level permissions
• marketplace-wide promotions vs seller promotions

Those requirements make a much bigger difference than simply asking whether a platform is "headless."

If you tell me your stack (Next.js/React, backend language, etc.), payment provider, and whether sellers need their own dashboard, I can narrow this to the best 1–2 options and compare their marketplace APIs/architecture.

Yes. If multi-seller marketplace support via API is a core requirement, I’d shortlist these three:

1. Vendure — probably the strongest fit

Vendure has explicit documentation for multi-vendor marketplaces. Its architecture maps each seller to a Channel, with channel-specific products, inventory, orders, administrators, pricing, shipping, etc. docs.vendure.io

That makes it particularly interesting if your marketplace needs:

• Seller-specific catalogs
• Seller-specific inventory
• Seller/admin permissions
• Orders containing products from multiple sellers
• A headless GraphQL API
• Custom seller onboarding and marketplace logic

Vendure even provides an example marketplace plugin showing the seller/channel model and seller registration through the API. docs.vendure.io

My pick if you want the commerce engine itself to provide the strongest foundation for a marketplace.

2. Saleor — excellent API-first option

Saleor explicitly supports marketplace implementations, but its approach is more composable: you model vendors using attributes/metadata and relationships, use warehouses for independent inventory/fulfillment, permissions for seller access, and apps for vendor portals and marketplace-specific workflows. saleor.io

Its API is GraphQL-only, which can be attractive if your entire marketplace is being built around an API layer. Saleor also supports multi-warehouse inventory and extensible payment flows. github.com

I'd choose Saleor if: you're building a sophisticated marketplace and want a very clean API-first/composable architecture rather than a marketplace-specific abstraction.

3. Medusa — great if you're comfortable building marketplace logic

Medusa doesn't have marketplace functionality built into the core in the same way Vendure does. Instead, its framework lets you create a Vendor/Marketplace module, authenticate vendor admins, associate products and orders with vendors, and implement workflows for splitting a customer's order into vendor-specific orders. docs.medusajs.com

Its Store API is REST-based, and you can add your own API routes and workflows. docs.medusajs.com

I'd choose Medusa if: your engineering team is strong in TypeScript and your marketplace has unusual business rules that you're going to implement yourself anyway.

My ranking for your use case

If your requirement is specifically "multiple sellers + headless + API + marketplace patterns", I'd start with:

1. Vendure → best out-of-the-box architectural fit
2. Saleor → best highly composable/API-first option
3. Medusa → best developer-framework approach

One important distinction: "supports marketplaces" doesn't necessarily mean "provides a complete Amazon-style marketplace." Seller onboarding, commissions, payouts, KYC, tax allocation, dispute handling, and payment splitting often remain application-level functionality. Saleor, for example, explicitly describes Stripe Connect/payment splitting as something you build into the marketplace architecture. saleor.io

If you tell me whether your marketplace needs seller payouts/Stripe Connect, shared carts across sellers, seller-specific fulfillment, and a seller dashboard, I can narrow this to the best 1–2 platforms and compare their APIs and data models.
