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

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. 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.

Mirakl Marketplace Platform

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.

VTEX Developer Portal

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

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

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.

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.
