For a 10-person startup building a high-traffic headless storefront, I’d shortlist Medusa, Saleor, and Vendure. My default recommendation would be Medusa, unless you have a strong reason to prefer GraphQL/Python or need Saleor’s particular commerce model.

My ranking

The current open-source headless shortlist is essentially Medusa, Saleor, and Vendure, with each making a different tradeoff around language, architecture, and extensibility. Vendure OpenReplay Blog

1. Medusa — my default choice

medusajs.com

For a 10-person startup, I'd probably start here.

Medusa is TypeScript/Node-based, modular, headless, and MIT-licensed at its core. Its architecture separates API routes, workflows, commerce modules, and the underlying datastore, which is a nice fit when you expect to customize business logic rather than fight a monolithic platform. Medusa Docs GitHub

Why I like it for your situation:

• Same language as a modern React/Next.js storefront.
• You can heavily customize commerce behavior without forking an enormous monolith.
• PostgreSQL + Redis is a familiar operational stack.
• Good fit for a small team that needs to move quickly.
• MIT licensing is startup-friendly.
• You can put the storefront behind a CDN and keep the commerce API focused on dynamic operations.
• Its modular architecture gives you a reasonable path to replacing/customizing individual pieces as you scale.

The important caveat: don't interpret "high traffic" as "the commerce backend must handle every page request." Your architecture should make most storefront traffic static/cacheable.

I'd aim for:

                         ┌── CDN / Edge ──┐
                         │                │
Browser ──> Next.js ─────┤ cached pages   │
                         │ cached assets  │
                         └───────┬────────┘
                                 │
                         dynamic requests
                                 │
                          ┌──────▼──────┐
                          │   Medusa    │
                          │ commerce API│
                          └──┬─────┬───┘
                             │     │
                         Postgres Redis
                             │
                   ┌─────────┴─────────┐
                   │ search / payments │
                   │ ERP / fulfillment │
                   └───────────────────┘

That separation matters much more to scalability than whether you choose Medusa versus Saleor.

2. Saleor — strongest alternative

saleor.io

I'd seriously consider Saleor if your team likes GraphQL and you're expecting sophisticated multi-channel/global commerce.

Saleor is API-only and GraphQL-first, with native concepts around channels, currencies, stock, products, promotions, payments, and multi-region commerce. It also has an official Next.js/React/TypeScript storefront example. Saleor Documentation GitHub

It's particularly attractive if you're building something like:

• multiple storefronts
• multiple countries/currencies
• complicated pricing
• multiple warehouses
• B2B + DTC
• marketplace-like functionality
• lots of independent frontend clients

Its architecture is deliberately API-first rather than relying on a traditional plugin-heavy monolith. Saleor Commerce

I'd choose Saleor over Medusa if the commerce model is complex enough that its existing primitives map unusually well to your business.

The downside for a small startup is that you're taking on a Python/Django backend even if the rest of your team is TypeScript.

3. Vendure — worth a serious look

vendure.io

Vendure is compelling if you're an all-TypeScript team but want a more structured NestJS/GraphQL commerce framework.

It's especially interesting for B2B, multi-channel, and heavily customized commerce. The tradeoff I'd investigate carefully is its GPLv3 licensing versus Medusa's MIT core. Current comparisons also put Vendure behind Medusa in ecosystem/community size, although it's a mature project. Vendure ShipGarden

For a startup, I wouldn't choose it merely because it benchmarks well. I'd choose it if Vendure's plugin/domain model fits your product better than Medusa's.

What I would not do

I wouldn't start with WooCommerce, Magento, or PrestaShop for this particular project unless you have a very specific reason.

They're excellent software in their respective niches, but you're describing a new, high-traffic, headless product with a 10-person engineering team. I'd rather start with a commerce engine designed around APIs than turn a traditional CMS/ecommerce system into one.

I also wouldn't build the entire commerce backend from scratch. You'd quickly find yourselves recreating:

• carts
• pricing
• promotions
• inventory
• orders
• payments
• fulfillment
• refunds
• tax
• customer accounts
• product variants
• channels
• webhooks
• admin tooling

That's a terrible place for a 10-person startup to spend its engineering budget.

The decision I'd make

If I were on your team:

1. Medusa — default choice.
2. Saleor — choose this if GraphQL + sophisticated multi-channel/global commerce are central.
3. Vendure — choose this if you're deeply TypeScript/NestJS-oriented and its plugin architecture fits you.

And I'd spend considerably more time designing the scaling architecture around the commerce engine than debating these three.

For a high-traffic storefront, I'd want CDN/edge caching, Next.js or equivalent, aggressive read caching, PostgreSQL with replicas where appropriate, Redis, asynchronous workflows/queues, external search, and idempotent payment/order operations. The commerce platform should sit behind that architecture rather than being directly exposed to every page view.

If you tell me roughly (a) expected peak requests/sec, (b) SKU count, (c) B2C vs B2B, (d) whether you're all-TypeScript, and (e) whether you're self-hosting, I can narrow this to a concrete recommendation and deployment architecture.

For a 10-person startup building a high-traffic headless storefront, I’d shortlist Medusa, Saleor, and Vendure. I would not start with WooCommerce/Magento unless you have a specific reason to inherit their ecosystems.

My ranking

1. Medusa — my default choice

For a 10-person startup, I'd probably pick Medusa.

It's TypeScript/Node-based and designed as a modular, headless commerce engine rather than a giant monolithic storefront. That fits a small engineering team particularly well: your frontend can be Next.js/React, while the commerce backend handles products, carts, orders, payments, promotions, fulfillment, etc. Current comparisons also put Medusa ahead when the team is primarily JavaScript/TypeScript. ShipGarden OSSAlt

The big advantages for you:

• TypeScript end-to-end, reducing context switching.
• Modular architecture, so you don't have to fork the platform for every customization.
• Headless from the beginning, rather than retrofitting an old monolith.
• MIT license, which is attractive for a startup that wants maximum freedom.
• Good fit for building your own high-performance caching/CDN strategy around the commerce API.

medusajs.com

The caveat: Medusa is an engine, not a turnkey ecommerce business. Your team will still own a meaningful amount of application architecture and integrations. That's actually a positive if your storefront itself is the product differentiator.

2. Saleor — choose this if commerce complexity is the hard part

I'd seriously consider Saleor if you're doing things like:

• multiple countries/currencies
• multiple warehouses
• B2B pricing
• many sales channels
• complex catalog structures
• sophisticated inventory
• GraphQL everywhere

Saleor is Python/Django and GraphQL-only, with native multi-channel capabilities and an API-first architecture. Its own documentation emphasizes that the API is the only way to interact with and extend the backend. GitHub Saleor Commerce

That's a very attractive architecture for a high-traffic storefront because you can put your own BFF/cache layer in front of it and keep the customer-facing application decoupled.

saleor.io

The downside for a typical startup: if your engineers are all TypeScript, you're introducing a Python/Django backend that the team has to understand and operate.

3. Vendure — the one I'd benchmark against Medusa

Vendure is also TypeScript-based, built around NestJS, and uses GraphQL. It's particularly interesting if you anticipate B2B, multi-channel, marketplace, or multi-brand requirements. Vendure Grafen

Its architecture is appealing for an engineering-heavy team: rather than modifying core behavior, you can implement strategies/plugins for things like pricing, shipping, tax, and promotions.

vendure.io

The main thing I'd investigate before committing is its GPLv3 licensing model versus Medusa's MIT license. That's not necessarily a problem, but it's worth having your lawyer review given that you're a startup.

What I'd actually build

For your situation, I'd lean toward:

Next.js storefront → CDN/edge cache → your BFF/API layer → Medusa → PostgreSQL + Redis

And I'd deliberately keep the high-traffic path away from the transactional commerce backend where possible.

For example:

                    ┌───────────────┐
                    │   CDN / Edge  │
                    └───────┬───────┘
                            │
                    ┌───────▼───────┐
                    │ Next.js / BFF  │
                    └───────┬───────┘
                            │
              ┌─────────────┴─────────────┐
              │                           │
       catalog/search               transactions
              │                           │
       ┌──────▼──────┐             ┌──────▼──────┐
       │ cache/search│             │   Medusa    │
       │ layer       │             │             │
       └─────────────┘             └──────┬──────┘
                                          │
                                  ┌───────┴───────┐
                                  │ PostgreSQL    │
                                  │ Redis / jobs  │
                                  └───────────────┘

The important point is that "high traffic" shouldn't mean trying to make the ecommerce application itself serve every product-page request. Cache aggressively at the edge, isolate reads from writes, use a dedicated search system if the catalog warrants it, and treat checkout/order operations as the comparatively small transactional workload.

My decision rule

If you told me:

"We're 10 engineers, all comfortable with TypeScript, we're building a custom React/Next.js storefront, and we expect potentially millions of visitors."

I'd choose Medusa first, prototype the hardest commerce workflows, and benchmark it under your catalog/order workload.

I'd choose Saleor instead if you said:

"We're doing international/B2B/multi-channel commerce and have Python expertise."

And I'd choose Vendure if you said:

"We're TypeScript-heavy, want NestJS/GraphQL, and expect substantial B2B or multi-store customization."

One important distinction: don't choose based on benchmarked requests/sec alone. At high traffic, CDN/cache strategy, search, database design, personalization, observability, and how you partition read-heavy versus transactional workloads will matter far more than whether Commerce Engine A can do 500 vs. 700 API requests/sec.

For a 10-person team, I'd optimize for how little custom infrastructure you have to maintain while retaining architectural control. That's why Medusa is my starting point. ShipGarden pkgpulse.com

For a 10-person startup building a high-traffic headless storefront, my default recommendation would be medusajs.com—with saleor.io as the main alternative and vendure.io worth considering if you're strongly TypeScript/NestJS-oriented.

My shortlist

Why I'd pick Medusa

The important thing for your situation isn't merely "does it support headless?"—all three do. It's how much engineering capacity your 10-person team has to spend maintaining the commerce backend instead of building your product.

Medusa's architecture is particularly well suited to this: API routes sit over workflows and modular commerce components, with PostgreSQL as the normal persistence layer and Redis available for locking/workflow infrastructure. Medusa Documentation

Your storefront is also genuinely decoupled from the backend. Medusa documents the storefront as a separately built and hosted application, including Next.js support, which makes it straightforward to put your high-traffic read path behind a CDN/cache layer. Medusa Documentation

And its modular architecture means you can replace/customize things like payments, fulfillment, pricing, inventory, and other business logic without turning the whole commerce engine into a fork. Medusa Documentation

For a startup, I particularly like TypeScript end-to-end + MIT licensing. You don't need a separate Python backend team, and you're less likely to encounter licensing questions as you build proprietary extensions.

When I'd choose Saleor instead

I'd seriously consider Saleor if your requirements look more like:

• Lots of B2B functionality
• Multiple warehouses/channels/markets
• GraphQL is a strong architectural preference
• You already have a strong Python/Django team
• Commerce domain complexity is more important than minimizing engineering overhead

Saleor is GraphQL-first and has a mature extension/app model; its official project emphasizes channels, product types, shipping/tax configuration, and independently versioned apps. Saleor Commerce

The downside for a typical 10-person JavaScript/TypeScript startup is that you're introducing a Python/Django backend into an otherwise potentially TypeScript-heavy stack.

When I'd choose Vendure

Vendure is compelling if your team is deeply invested in TypeScript and NestJS and you want a very extensible commerce framework.

I'd favor it over Medusa if you have unusually complex multi-channel, B2B, marketplace, or organizational requirements and you're comfortable with its GPLv3 licensing model. Current comparisons also put Vendure's strength in its TypeScript-native architecture and extensibility. Vendure Grafen

The smaller ecosystem is the tradeoff I'd worry about for a startup: when you're debugging something at 2 a.m., community size and available integrations matter.

One important caveat about "high traffic"

I wouldn't select the commerce engine based on its advertised request/sec number.

For a high-traffic storefront, I'd architect it roughly as:

CDN → Next.js storefront → cache/search layer → commerce API → PostgreSQL

with:

• CDN/edge caching for product/category/content pages
• Dedicated search infrastructure rather than hammering PostgreSQL for catalog search
• Aggressive caching for catalog reads
• PostgreSQL with proper indexes, connection pooling, replicas where justified
• Redis for appropriate ephemeral state/work coordination
• Async workers for email, fulfillment events, webhooks, etc.
• Checkout/order creation kept on strongly consistent paths
• Load testing against your actual catalog and checkout workflows

The backend doesn't need to serve every anonymous product-page request. That's where headless architecture can really pay off.

What I'd do in your shoes

Start with Medusa + Next.js, unless you already know that you have Saleor-specific requirements.

I'd spend the initial engineering effort on making the read-heavy catalog path aggressively cacheable, rather than trying to make the commerce API itself handle enormous anonymous traffic.

Medusa's deployment model also supports separating the Medusa application from one or more storefronts, and its managed option can handle infrastructure such as the server, database, and Redis if you decide that operating all of this isn't a good use of your team's time. Medusa Documentation

If you tell me your expected requests/sec, SKU count, catalog update frequency, regions, B2C vs B2B, and whether you're using Next.js, I can narrow this down much further and sketch the architecture I'd use for the 10-person team.

CDN → Next.js storefront → cache/search layer → commerce API → PostgreSQL

with:

For a 10-person startup building a headless storefront that needs to handle high traffic, I'd shortlist Medusa, Saleor, and Vendure. I would not start with WooCommerce/Magento unless you have a specific reason to inherit their ecosystems.

My recommendation: Medusa

Medusa would be my default choice for your team.

It is TypeScript/Node.js, headless-first, modular, and MIT-licensed at its core. Its architecture separates API routes, workflows, commerce modules, and PostgreSQL, which makes it a good foundation for a custom high-traffic storefront rather than something you're trying to turn headless after the fact. docs.medusajs.comgithub.com

Medusa documentation

Why I'd pick it for a 10-person team:

• TypeScript end-to-end — particularly attractive if your storefront is Next.js/React.
• Headless by design rather than an adaptation of a monolithic CMS.
• Modular architecture means you can replace/customize pricing, payments, fulfillment, etc.
• MIT core license, which is a nice property for a startup building proprietary functionality around it. docs.medusajs.comgithub.com
• Large and active developer community; its GitHub repo currently has ~35K stars. docs.medusajs.comgithub.com
• You can keep the storefront extremely cache-heavy and make the commerce API responsible for the genuinely dynamic operations.

The important caveat: Medusa isn't what makes a high-traffic storefront fast. Your architecture around it does.

I'd aim for:

                    CDN / Edge
                        │
                  Next.js Storefront
                        │
              ┌─────────┴─────────┐
              │                   │
         Cacheable APIs      Dynamic APIs
              │                   │
              └─────────┬─────────┘
                        │
                     Medusa
                   /    │    \
             Redis   PostgreSQL  Workers
                        │
                 Search / Payments

Keep product/category/content pages aggressively cached at the edge, and make checkout/cart/inventory/order operations the small dynamic portion of the system.

The alternatives

Saleor is the one I'd investigate most seriously alongside Medusa. Saleor is GraphQL-only, API-only, cloud-native, and explicitly designed for composable/headless commerce. It has particularly strong multi-channel capabilities and is a compelling choice if you're expecting sophisticated internationalization, multiple warehouses/channels, or enterprise B2B. github.com

Saleor open-source project

Vendure is my third choice. Vendure It's TypeScript/NestJS and has a very extensible plugin architecture. I'd move it to #1 if your requirements are heavily B2B/multi-channel and your team already loves NestJS. The GPLv3 licensing model is something I'd have your lawyer review before committing. vendure.io

Vendure

What I would not optimize for

Don't choose based primarily on "which one can handle the most requests/sec." For a high-traffic store, the commerce engine should rarely be in the hot path for anonymous page views.

I'd instead evaluate these five things with a proof-of-concept:

1. Catalog size — 100K products is a very different problem from 10M.
2. Traffic shape — millions of cached product-page views vs. huge concurrent checkouts.
3. Inventory semantics — especially flash sales and overselling prevention.
4. Search — whether you're using Algolia/Typesense/Elastic/OpenSearch rather than hammering the commerce DB.
5. Checkout extensibility — payment, promotions, tax, shipping, fraud, and order workflows.

For a 10-person company, I'd strongly favor buying/using an existing commerce engine and spending your engineering budget on the differentiated storefront, rather than building the commerce backend yourselves.

Bottom line:
Medusa if you're primarily a TypeScript/React startup and want maximum control with minimal organizational overhead. Saleor if you're expecting sophisticated multi-channel/B2B/enterprise commerce. Vendure if you're TypeScript/NestJS-native and its licensing model works for you.

If you tell me your expected peak RPS, catalog size, B2C vs B2B, countries/currencies, and whether you're on Next.js, I can narrow this down to one and sketch the production architecture I'd use.

For a 10-person startup building a high-traffic headless storefront, my shortlist would be:

1. Saleor — my pick for highest-scale / most demanding storefronts
2. Medusa — my pick for fastest development and a TypeScript-heavy team
3. Vendure — excellent if you need deep customization/B2B

My recommendation: Saleor

I'd lean Saleor if "high traffic" is a core requirement rather than just marketing language.

It's genuinely API-only/headless, GraphQL-first, cloud-oriented, and designed around composability. It also has native multichannel support and a Next.js/React/TypeScript storefront reference implementation. github.com

The important architectural advantage for you is that you can keep the storefront extremely independent:

CDN → Next.js → Saleor GraphQL → PostgreSQL/Redis/etc.

That lets you aggressively cache product/category/content reads at the edge while keeping checkout, inventory, pricing, and order mutations dynamic.

Saleor's core is BSD-3 licensed, which is also attractive for a startup that wants to own its deployment. github.com

When I'd choose Medusa instead

Choose Medusa if your team is primarily TypeScript/Node.js and you value developer velocity over having the most opinionated commerce platform.

Medusa is particularly appealing for a 10-person team because its architecture is modular and its core is MIT licensed. github.com

I'd probably choose it if you're building something that is commerce-adjacent rather than a conventional store—for example, unusual pricing, marketplace behavior, subscriptions, custom fulfillment, or lots of bespoke business logic.

The tradeoff is that you'll likely own more of the architecture yourself.

Vendure

Vendure is a very good third option, especially if you're already a NestJS/TypeScript shop. Its plugin architecture is excellent, and it can run self-hosted, in Docker/Kubernetes, or on its managed platform. github.com

The big caveat for a startup is licensing: the community edition is GPLv3, with a commercial license available. That's something I'd get legal comfortable with before committing. github.com

What I'd actually do with 10 engineers

One thing I'd not do: pick based on raw requests/sec benchmarks. For a high-traffic storefront, the commerce backend shouldn't be serving every anonymous product-page request anyway. Put the storefront behind a CDN, aggressively cache/catalog-read traffic, and reserve the commerce engine for dynamic operations.

If I were CTO of your startup: I'd prototype Saleor + Next.js + PostgreSQL + Redis + CDN first. If the team strongly prefers Node/TypeScript and wants maximum freedom to bend the commerce model, I'd switch that decision to Medusa.

The key question that could change my recommendation is what "high traffic" means for you—e.g. 1k, 10k, or 100k requests/sec, plus whether you need B2B, multi-region inventory, marketplace functionality, or just DTC.

For a 10-person startup building a high-traffic headless storefront, my default recommendation would be Medusa—with Saleor as the main alternative.

My ranking

🥇 Medusa — my pick for your team

If you're already building the storefront in Next.js/React, Medusa is particularly attractive because the backend is TypeScript/Node as well. Its architecture is modular, so you can replace or customize pieces such as inventory, payments, fulfillment, and order workflows rather than fighting a monolithic ecommerce system. contracollective.com

For a 10-person startup, that's important: you want an ecommerce engine, not another giant platform your team has to become experts in.

I'd run roughly:

CDN → Next.js storefront → Medusa API → PostgreSQL + Redis → async workers → external payment/search/ERP services

And make the storefront aggressively cacheable. Your high traffic should primarily hit the CDN and your read paths—not your commerce database.

Medusa

🥈 Saleor — if your commerce model is genuinely complex

Saleor is the one I'd investigate seriously if you're expecting things like:

• huge/complex catalogs
• multiple countries, currencies and channels
• sophisticated warehouse/inventory requirements
• GraphQL as a core architectural choice
• enterprise/B2B commerce

It's Python/Django + GraphQL rather than TypeScript, so there's a bigger organizational decision for a JS-heavy startup. But its commerce model is very capable. contracollective.com

Saleor

🥉 Vendure — worth considering for B2B

Vendure is also TypeScript/NestJS and has an excellent plugin architecture. I'd move it up the list if you're building B2B commerce with customer-specific pricing, organizations, approvals, quotes, etc. contracollective.com

The licensing model deserves legal review before committing, though.

Vendure

What I would not optimize for

Don't pick based primarily on "which handles the most requests/sec." At your scale, the architecture around the commerce engine will matter enormously more:

• CDN/cache strategy
• database indexing and read/write separation
• async jobs
• search infrastructure
• image optimization
• idempotent checkout/order APIs
• inventory contention
• observability
• rate limiting
• failure/retry behavior

A well-architected Medusa deployment can be a much better high-traffic system than a poorly architected "enterprise" platform.

Bottom line: if I were CTO of your 10-person startup, I'd start with Medusa + Next.js + PostgreSQL + Redis, and run a serious proof-of-concept against Saleor if your catalog/multi-region requirements are unusually complex. The current 2026 landscape broadly supports that split: Medusa for composability and TypeScript velocity, Saleor for more complex enterprise commerce, Vendure for specialized TypeScript/B2B use cases. contracollective.com

If you tell me your expected peak requests/sec, SKU count, regions, B2C vs B2B, and whether you're already TypeScript/Next.js, I can narrow this down much more concretely.

For a 10-person startup building a high-traffic headless storefront, I’d shortlist Saleor, Medusa, and Vendure. My default recommendation would be Saleor, with Medusa as the alternative if your team is strongly TypeScript/Node-oriented.

1. 🏆 Saleor — my choice for your situation

Saleor is specifically designed around a high-performance, API-only/headless architecture, with GraphQL as the primary interface. It supports multichannel commerce, complex catalogs, multiple currencies, inventory, and extensibility through apps/webhooks rather than requiring you to fork the core. github.com

For a small team, that's important: you get a lot of mature commerce functionality without having to build the boring-but-dangerous pieces yourselves.

The other thing I like for your use case is that Saleor's architecture lends itself naturally to:

CDN → Next.js storefront → GraphQL API → cached/read-heavy commerce paths → PostgreSQL/Redis/etc.

You can keep the storefront independently scalable from the commerce backend.

The core is BSD-licensed, which is also unusually friendly if you're building proprietary infrastructure around it. github.comgithub.com

I'd pick Saleor if: you're expecting genuinely large traffic, international/multichannel commerce, or a catalog/order model that's going to get complicated.

Saleor GitHub

2. Medusa — best if your team is TypeScript-native

Medusa is probably the one I'd evaluate immediately alongside Saleor.

It's TypeScript/Node-based, MIT licensed, and designed as a modular commerce framework. The current architecture gives you modules for things like products, orders, payments, fulfillment, and customers without forcing you into a monolithic storefront. github.com

For a 10-person engineering team, developer experience may actually outweigh raw architectural differences. If everyone already lives in TypeScript/React/Next.js, Medusa lets you stay in that ecosystem.

I'd choose it over Saleor if your product is more application-like than traditional ecommerce—e.g. unusual checkout flows, marketplace-like behavior, custom business logic, or lots of bespoke commerce workflows.

Medusa GitHub

3. Vendure — excellent, particularly for complex domain logic

Vendure is another strong TypeScript choice. It's built on NestJS and GraphQL and has a particularly good plugin architecture: you can extend the system through plugins rather than maintaining a fork. github.com

I'd seriously consider it if you're doing B2B, complex pricing, multiple channels, marketplace functionality, or unusual business rules.

The main thing I'd flag for a startup is licensing: Vendure Core is GPLv3, versus MIT for Medusa and BSD-3-Clause for Saleor's core. github.comgithub.com

Vendure GitHub

What I would not optimize for

Don't choose based primarily on benchmark claims like "X requests/sec." For high traffic, your storefront architecture matters enormously more than the ecommerce framework's theoretical throughput.

I'd architect it roughly like:

                    CDN / Edge
                        │
                 Next.js storefront

Keep product/category/content pages aggressively cacheable. Don't make every anonymous page request hit your commerce database. Treat checkout, cart, inventory, pricing, and customer-specific data as the dynamic path.

My decision rule

If I were your CTO, I'd do a 2–3 day spike with Saleor and Medusa, implementing the same:

• 100k+ product catalog
• category/search page
• PDP
• cart
• checkout
• inventory update
• webhook/event flow
• 10× expected peak traffic load test

Then pick whichever produces the simplest production architecture, not whichever wins a synthetic benchmark.

My starting bet: Saleor 60%, Medusa 30%, Vendure 10%.

If you tell me roughly expected requests/sec or concurrent users, catalog size, PostgreSQL/Redis/cloud stack, and whether you're B2C or B2B, I can narrow this down substantially and suggest a concrete production architecture.

For a 10-person startup building a high-traffic headless storefront, I’d shortlist Medusa, Saleor, and Vendure—and my default choice would be Medusa unless you have unusually complex catalog/multi-region requirements.

My ranking

1. Medusa — my pick

Medusa is built specifically as a composable commerce backend, with commerce functionality split into modules that you can customize rather than fighting a monolithic platform. Its core modules are open source and available through npm. github.com

For a 10-person team, that's attractive because you can keep the architecture relatively simple:

Next.js storefront → CDN/cache → Medusa → Postgres + Redis → external search/payment/etc.

I'd choose it if:

• Your team is primarily TypeScript/Node
• You're building a differentiated buying experience
• You expect substantial custom business logic
• You want to move quickly without building commerce primitives yourself
• You want the option of managed infrastructure later

Its main advantage for a startup is developer velocity rather than theoretical maximum scale.

Medusa GitHub

2. Saleor — strongest if "high traffic" really means large-scale commerce

Saleor is the one I'd investigate most seriously if you're expecting very high traffic, internationalization, multiple storefronts/channels, complex catalogs, or significant operational scale.

It's API-only and GraphQL-native, with multi-channel capabilities and an architecture designed to keep extensions outside the core. Saleor explicitly positions scalability and independent scaling of extensions as architectural goals. github.com

The downside for a 10-person startup is that you're taking on a Python/Django/Celery ecosystem rather than staying entirely in TypeScript.

So:

**If your team is Node/TS → Medusa.
If your commerce architecture is unusually sophisticated → Saleor.**

Saleor GitHub

3. Vendure — excellent TypeScript alternative

Vendure is compelling if you want TypeScript but prefer a more structured, enterprise-style architecture. It's built on NestJS, exposes separate Shop/Admin GraphQL APIs, and has a plugin architecture designed to let you extend the system without modifying core code. docs.vendure.iogithub.com

I'd favor it over Medusa if you're expecting things like:

• sophisticated B2B organizations/permissions
• complex pricing
• multiple channels
• extensive plugins/customizations
• a team that already likes NestJS

One important consideration: Vendure Core is GPLv3, whereas Medusa is MIT, so have your counsel review the licensing implications for your particular distribution/deployment model. docs.vendure.iogithub.com

Vendure GitHub

What I would not pick

I wouldn't start a new high-traffic headless startup project with WooCommerce/Magento/Shopware unless you have a specific reason to. They're excellent ecosystems, but for a greenfield, engineering-led product, the newer headless platforms generally give you a cleaner architectural starting point.

The bigger issue: don't optimize the commerce backend for storefront traffic

This is the architectural distinction I'd make with your team:

10 million page views ≠ 10 million commerce API requests.

Put the storefront behind a CDN and aggressively cache product/category/content responses. Keep the commerce backend primarily responsible for dynamic operations:

• cart
• checkout
• inventory
• pricing
• customer state
• orders
• payment

That means a properly designed Medusa/Saleor/Vendure deployment can handle a very large storefront without requiring your commerce database to serve every page view.

For your specific situation, I'd prototype Medusa first, Saleor second. Spend a week implementing your hardest flows—catalog, pricing, cart, checkout, inventory, promotions—and see which model feels less constraining. The difficult-to-replace decision isn't the storefront framework; it's the commerce domain model.

If you tell me your expected traffic/GMV, SKU count, B2C vs B2B, regions, and preferred stack (TS/Python), I can narrow this down considerably and propose a production architecture for a 10-person team.

For a 10-person startup building a headless storefront that needs to handle high traffic, I'd shortlist Medusa, Saleor, and Vendure, with Medusa as my default recommendation.

1. 🥇 Medusa — my default choice

Medusa

For a 10-person engineering team, I'd lean Medusa unless you have unusually complex catalog/multi-region requirements.

Its architecture is particularly appropriate for a startup: HTTP API → workflows → domain modules → PostgreSQL, with modules that can be extended or replaced. docs.medusajs.com

That gives you a good balance of:

• TypeScript/Node.js, so your storefront and commerce backend can share the same ecosystem.
• Modular domains for products, carts, orders, inventory, payments, etc.
• Freedom to build your own Next.js/React storefront.
• Less need to fight a monolithic ecommerce application's assumptions.
• A relatively small engineering team can understand the whole system.

For high traffic, I'd not interpret "high traffic" as requiring an exotic ecommerce engine. Put the storefront behind a CDN, aggressively cache catalog/PDP responses, keep checkout/order mutations uncached, and scale the commerce API horizontally. The database and inventory/order consistency are likely to become more important bottlenecks than raw HTTP throughput.

2. 🥈 Saleor — strongest if you're building sophisticated global commerce

Saleor

I'd seriously consider Saleor if you expect:

• multiple countries/currencies/channels,
• complicated catalogs,
• multiple warehouses,
• substantial enterprise-scale traffic,
• GraphQL as a core architectural choice.

Saleor is GraphQL-native and explicitly designed for headless/composable implementations; its current architecture also emphasizes APIs, webhooks, and external extensions rather than requiring you to modify the core. saleor.io

The tradeoff for your 10-person team is that you're taking on a Python/Django ecosystem rather than staying entirely in TypeScript. That's not inherently bad, but if everyone is already a TS/Node engineer, it creates an organizational cost.

3. 🥉 Vendure — excellent if you're TypeScript + GraphQL + plugins

Vendure

Vendure is probably the one I'd put through a bake-off against Medusa.

It's TypeScript/NestJS, GraphQL-based, and has a very coherent architecture: the server handles APIs while a separate worker handles background jobs such as search indexing and email. Servers and workers can scale independently. docs.vendure.io

I'd favor it over Medusa if you expect B2B complexity—customer-specific pricing, organizations, approvals, sophisticated promotions, etc.—or if you particularly like the NestJS/plugin model.

One thing I'd investigate carefully before committing is the current Core vs. commercial Platform licensing/features, because Vendure's offering has evolved. vendure.io

What I'd build with 10 people

If you told me "we need to launch, but expect potentially millions of storefront requests during traffic spikes," I'd probably use:

Next.js storefront → CDN/edge cache → Medusa → PostgreSQL + Redis → async workers

with external services for things that don't need to live inside the commerce engine:

• Search: Algolia / OpenSearch / Elasticsearch
• CMS: Sanity / Contentful / Payload
• Payments: Stripe/Adyen/etc.
• CDN: Cloudflare/Fastly
• Observability: OpenTelemetry + your preferred backend
• Queue/event infrastructure as traffic requires it

The important architectural decision is not to make the ecommerce backend serve every storefront request dynamically. Product/category/content pages should be heavily cacheable. Checkout, cart, customer and inventory operations are where you want strong consistency.

My decision rule

Choose Medusa if you're a typical 10-person TypeScript startup and want maximum development velocity.

Choose Saleor if you're already thinking about global/multi-channel commerce and very large catalogs.

Choose Vendure if your business model is B2B-heavy or you strongly prefer NestJS/GraphQL/plugin architecture.

I would not start with Magento/Adobe Commerce or WooCommerce for this particular project unless you have a specific ecosystem requirement. They're enormously mature, but you're choosing a lot of legacy/platform machinery when your stated goal is a modern headless storefront.

If you give me your expected requests/sec, SKU count, number of countries, B2C vs B2B, and whether the team is TypeScript/Python, I can narrow this down to a concrete architecture and tell you which one I'd actually deploy.

For a 10-person startup building a high-traffic headless storefront, I would shortlist Medusa, Saleor, and Vendure. I would not start with Magento/Adobe Commerce or WooCommerce unless you have a very specific reason—they can scale, but they bring more legacy complexity than most small product teams want. blog.openreplay.com

My default recommendation:

1. Medusa — best fit for most 10-person startups

Pick this if your team is TypeScript/Node-oriented and you want to move fast. contracollective.comvendure.io

Why I’d lean here:

• TypeScript end-to-end → easier hiring and faster iteration
• Headless-first architecture
• Modular commerce primitives (catalog, cart, orders, payments, fulfillment)
• Easier to customize than traditional ecommerce platforms
• Good fit for a custom storefront with a Next.js/React stack designodin.com

Watch-outs:

• You own more of the commerce architecture
• Complex inventory, OMS, ERP, or marketplace flows may require engineering work
• You need strong observability and load testing for high traffic

A typical stack:

• Next.js storefront
• Medusa backend
• PostgreSQL
• Redis
• OpenSearch/Elasticsearch for search
• Stripe/Adyen for payments
• CDN + edge caching

For a startup, this is usually the best balance of speed + control.

2. Saleor — best if you have enterprise-style complexity

Choose this if you expect:

• Multi-region
• Multi-currency
• Large catalogs
• Complex pricing
• Multiple warehouses
• GraphQL-first APIs

Saleor is more opinionated and enterprise-oriented, with a strong GraphQL model and Python/Django stack. contracollective.com

Tradeoffs:

• Python/Django may slow a team that is entirely JS/TS
• More platform thinking required up front
• Smaller extension ecosystem than older commerce platforms

I’d choose Saleor over Medusa if your business model looks like:

• global retail
• marketplace
• complex SKU/variant management
• B2B + D2C hybrid

3. Vendure — best if you want a structured TypeScript commerce framework

Vendure is interesting for teams that like NestJS-style architecture and want strong plugin boundaries. contracollective.comvendure.io

Strengths:

• TypeScript
• GraphQL-first
• Clean plugin architecture
• Good fit for complex business logic

Tradeoffs:

• Smaller ecosystem
• More framework-like; you may build more yourself

What I would avoid for your situation

Magento / Adobe Commerce

Good for:

• huge catalogs
• enterprise merchants already invested in Magento

Bad fit for:

• a 10-person startup wanting velocity

You’ll likely spend too much time operating the platform.

WooCommerce

Great ecosystem, but it is not really designed as a modern high-scale headless commerce backend. You can make it work, but you’ll fight the architecture.

My ranking for your exact profile

The biggest question is not traffic alone—it is where your complexity lives:

• Complex frontend + custom buying experience → Medusa
• Complex catalog, regions, inventory → Saleor
• Complex business workflows/B2B → Vendure

For a 10-person team, I would probably start with Medusa unless you already know you need Saleor-level commerce complexity. contracollective.comvendure.io

I’d also spend time designing the architecture around search, caching, inventory consistency, checkout reliability, and observability—those are usually the bottlenecks at high traffic, not the storefront framework itself.

For a 10-person engineering-heavy startup building a headless storefront for high traffic, I'd shortlist Medusa, Saleor, and Vendure—and I'd probably start with Medusa unless your requirements point strongly toward Saleor.

1. Medusa — my default recommendation

For a 10-person startup, I'd favor Medusa because it gives you a headless, modular commerce backend without forcing you into a giant enterprise architecture. Its commerce modules are open source, and the framework is explicitly designed for building customized commerce applications rather than treating the storefront as an afterthought. github.com

It's particularly attractive if your team is already TypeScript/Node-heavy. You can keep your stack relatively coherent:

Next.js/React → CDN/edge → BFF → Medusa → Postgres/Redis → async workers/search/payment services

For high traffic, I would not try to make the commerce backend serve every page directly. Cache aggressively at the storefront/API layer and make commerce operations—cart, checkout, inventory, orders—the strongly consistent path.

2. Saleor — strongest alternative for truly large-scale commerce

I'd choose Saleor over Medusa if you're expecting very large catalogs, multiple markets/channels, sophisticated inventory, or unusually high global traffic.

Saleor is GraphQL-only, headless/API-only, and designed around independently scalable extensions/apps. Its documentation specifically describes separating extensions from the core to improve reliability, upgrades, and independent scaling. github.com

The tradeoff is that you're adopting a more substantial Python/Django + GraphQL ecosystem. For a 10-person team, that's perfectly reasonable if you already have Python expertise, but I'd avoid introducing Python solely because Saleor benchmarks well.

3. Vendure — excellent TypeScript alternative

Vendure is particularly compelling if you want TypeScript end-to-end but prefer a more opinionated backend architecture.

It's built on NestJS, exposes separate Shop/Admin GraphQL APIs, and has a separate worker for background work such as search indexing and email. The server and worker can be scaled independently. docs.vendure.io

That's a very sensible architecture for high traffic.

The main thing I'd investigate before committing is its GPLv3/commercial licensing model and whether that fits your company's distribution/commercialization plans. github.comgithub.comvendure.io

What I would not choose

I wouldn't start a new high-traffic headless build on WooCommerce or Magento/Adobe Commerce unless you have a specific reason to need their enormous existing plugin/merchant ecosystems. They're mature, but you're taking on substantially more legacy/platform baggage than you need for a new headless product.

My decision rule

I'd make the choice like this:

• TypeScript team + highly customized DTC/product experience → Medusa
• Python team + global/multichannel/complex commerce → Saleor
• TypeScript + NestJS + complex B2B/domain logic → Vendure
• Need maximum control and you're willing to build/operate more infrastructure → Saleor or Medusa
• 10 engineers and need to ship quickly → Medusa

One important caveat: "high traffic" doesn't necessarily mean you need the most scalable commerce engine. Your storefront should absorb most of the traffic through CDN/edge caching; the commerce backend should be designed around relatively low-volume, state-changing operations. That architecture matters more than whether platform A can theoretically handle 2× platform B's requests.

If you tell me your expected requests/sec, catalog size, traffic geography, stack (Next.js/etc.), and whether you need B2B/multi-region/multi-warehouse, I can narrow this to one and sketch the architecture I'd use for a 10-person team.

For a 10-person startup building a high-traffic headless storefront, I’d shortlist Medusa, Saleor, and Vendure. I would not start from Magento/WooCommerce unless you specifically need their mature merchant ecosystems; they are usually a worse fit for a greenfield, API-first architecture. blog.openreplay.com

My default recommendation:

1. Medusa — probably my pick for your team

Medusa official site

Pick this if: your team is TypeScript/Node-heavy and you want maximum control.

Why it fits a 10-person startup:

• TypeScript end-to-end → easier hiring and faster iteration.
• Modular architecture → replace pieces as you outgrow defaults (pricing, inventory, fulfillment, payments).
• Good fit for a custom Next.js storefront, mobile apps, marketplaces, AI shopping experiences, etc.
• Less "platform-shaped" than traditional ecommerce systems; you can build your own workflows. contracollective.com

Potential concerns:

• You own more of the commerce complexity.
• You need strong engineering discipline around:
  • inventory consistency
  • order state machines
  • promotions
  • tax
  • fulfillment edge cases

For a startup with strong engineers, that tradeoff is often worth it.

My rating for your situation: 9/10

2. Saleor — best if commerce complexity is the hard part

Saleor official site

Pick this if: you expect enterprise-grade commerce requirements early.

Strengths:

• Excellent GraphQL-first API.
• Strong catalog modeling.
• Good for:
  • many SKUs
  • multiple regions/currencies
  • complex inventory
  • B2B-ish workflows. contracollective.comvendure.io

Tradeoffs:

• Python/Django stack.
• Less natural if your team is already a modern JS/TS shop.
• You may spend more time adapting the platform than with Medusa.

My rating for your situation: 8/10

3. Vendure — strong TypeScript alternative

Vendure official site

Pick this if: you like NestJS patterns and want a structured plugin system.

Strengths:

• TypeScript-native.
• Clean plugin architecture.
• Strong GraphQL model.
• Good for teams that want a more opinionated backend framework. contracollective.comvendure.io

Tradeoffs:

• Smaller ecosystem.
• Less mindshare than Medusa.
• You may build more integrations yourself.

My rating for your situation: 8/10

What I would build for a 10-person high-traffic startup

A stack I’d seriously consider:

Frontend:
Next.js / React
+
Edge CDN (Cloudflare/Fastly)

Commerce:
Medusa

Data:
PostgreSQL
Redis
OpenSearch/Elasticsearch (catalog search)

CMS:
Sanity / Contentful / Strapi

Payments:
Stripe

Infra:
Kubernetes or managed containers
Observability:
Datadog / Grafana

The commerce backend should not be responsible for everything. Keep:

• search → search engine
• content → CMS
• personalization → separate service
• analytics → event pipeline
• recommendations → separate ML/service layer

That separation matters more than squeezing every feature out of the commerce platform.

Questions that would change my recommendation

1. What does "high traffic" mean for you?
   • 100k visits/day?
   • 10M visits/day?
   • flash-sale spikes?

2. Are you:
   • DTC retail?
   • marketplace?
   • B2B?
   • subscriptions?

3. What is your stack?
   • TypeScript/Node?
   • Python?
   • Go?
   • something else?

4. How complex is inventory?
   • single warehouse?
   • multiple warehouses?
   • dropship?
   • real-time availability?

With only the information given, I’d start by prototyping Medusa + Next.js and keep Saleor as the benchmark if your catalog/order complexity is unusually high.

For a 10-person startup building a high-traffic headless storefront, I’d shortlist Saleor, Medusa, and Vendure. I would not start with Magento/Adobe Commerce unless you have unusually complex enterprise requirements.

My ranking

1. Saleor — my pick if traffic/scale is the priority

Saleor is particularly compelling if you're deliberately building a serious, API-first storefront rather than customizing an existing monolith. It's GraphQL-only, API-only, supports multiple channels, and is designed around a cloud-native architecture. github.com

The big advantage for your situation is that you can keep the storefront extremely thin:

CDN → Next.js/etc. → Saleor GraphQL → PostgreSQL/services

That separation is valuable when traffic spikes: most catalog/content traffic can be aggressively cached at the edge, while checkout/order operations hit the commerce backend.

The downside is that you're adopting Python/Django. For a 10-person startup, I'd only choose it if you're comfortable operating a Python service or already have Python expertise.

2. Medusa — best for a TypeScript startup

If your team is predominantly TypeScript/Node, I'd seriously consider Medusa over Saleor.

Medusa's architecture separates HTTP APIs, workflows, domain modules, and the data layer, and its modules can be replaced or extended. PostgreSQL is the normal persistence layer, with Redis and external infrastructure services available where appropriate. docs.medusajs.comgithub.com

That makes it attractive when you expect the product to become more than a conventional store—custom pricing, unusual checkout logic, marketplace-like functionality, custom fulfillment, etc.

It also has a very startup-friendly property: you can progressively customize the system instead of forking a giant ecommerce application. github.com

I'd choose Medusa if: your team is 8–10 JS/TS engineers and you expect substantial custom commerce logic.

3. Vendure — excellent dark horse

Vendure is probably the one I'd evaluate if you have strong TypeScript/NestJS engineers and expect sophisticated pricing, promotions, B2B, or custom workflows.

It's headless, GraphQL-based, TypeScript/NestJS, and heavily plugin-oriented. Its architecture explicitly separates the API server from background workers, which is a nice property for commerce workloads involving indexing, email, imports, and other asynchronous work. docs.vendure.io

The main thing I'd investigate carefully is the GPLv3 licensing/commercial model for your particular product and distribution model.

What I'd actually do with a 10-person team

If you told me:

"We're building a high-traffic DTC storefront, we're mostly TypeScript, and we want to move fast."

I'd pick Medusa.

If you told me:

"We're building infrastructure for very large catalogs/channels and traffic is our primary concern; GraphQL is a first-class requirement."

I'd pick Saleor.

If you told me:

"We're TypeScript/NestJS people and the commerce domain itself is going to be highly customized."

I'd pick Vendure.

One important caveat

Don't select based on "can the backend handle 100k requests/sec?" That's usually the wrong bottleneck for a headless store.

For high traffic, I'd architect it roughly as:

CDN/edge cache
↓
Next.js / custom storefront
↓
BFF/API layer
↓
Commerce engine
↓
Postgres + Redis + async workers

Keep product/category/search pages aggressively cacheable. Keep cart, inventory reservation, checkout, payment and order mutation paths uncached and carefully transactional.

In other words, your storefront architecture will have a much larger impact on peak traffic performance than whether you choose Saleor vs. Medusa vs. Vendure.

For a 10-person team, I'd also strongly prefer a platform where you can avoid modifying core code. Saleor's API/app approach, Medusa's modules/workflows, and Vendure's plugins all give you substantially better upgradeability than starting with a traditional monolithic ecommerce system. github.com

My default choice: Medusa for a TS startup; Saleor if scale/composability outweighs language familiarity.

For a 10-person startup building a high-traffic headless storefront, I’d shortlist Medusa, Saleor, and Vendure—but my default recommendation would be Medusa if your team is TypeScript/Node-heavy.

1. 🥇 Medusa — my default choice

Medusa is particularly attractive for a 10-person team because the architecture is familiar to modern web engineers: TypeScript/Node, PostgreSQL, Redis, and modular commerce services. Its request path is essentially API → workflow → module → datastore, and the modules/workflows can be replaced or customized. docs.medusajs.com

The MIT license is also unusually startup-friendly. github.com

I'd choose it if you're building something like:

Next.js storefront → CDN/cache → BFF → Medusa → Postgres/Redis → payment/search/ERP services

The important point is that high storefront traffic doesn't necessarily mean your commerce backend needs to handle every page request. I'd put aggressively cacheable product/category content behind a CDN and keep Medusa primarily responsible for dynamic operations: carts, checkout, pricing, inventory, orders, etc.

2. 🥈 Saleor — choose this if scale/commerce complexity dominates

Saleor is the one I'd seriously consider over Medusa if you're expecting very large catalogs, international/multi-channel commerce, or unusually high transaction volume.

Saleor is API-only and GraphQL-native, with a deliberately service-oriented extension model. Its own documentation emphasizes that extensions can be deployed and scaled independently rather than becoming plugins inside the core. github.com

It's also BSD-3-Clause licensed at the core. github.com

The downside for a 10-person team is organizational: you're taking on a Python/Django/PostgreSQL backend rather than staying in the TypeScript ecosystem. That's not inherently bad, but if your engineers are all JS/TS, Medusa/Vendure will probably have lower cognitive overhead.

3. 🥉 Vendure — excellent if you want a strongly typed commerce backend

Vendure is compelling if your team loves TypeScript/NestJS and expects to build substantial custom commerce behavior. It has a clean server/worker architecture, GraphQL Shop/Admin APIs, and a mature plugin/strategy model. docs.vendure.io

One thing I'd flag for a startup: Vendure Core is currently GPLv3, with a separate commercial license available. github.com That's materially different from Medusa's MIT and Saleor's BSD license, so I'd have your counsel look at the implications before committing.

What I'd do in your shoes

If you're TypeScript-heavy:
Medusa + Next.js + CDN + PostgreSQL + Redis, with search and other expensive workloads offloaded into dedicated services.

If you're Python-capable and expect serious international/catalog complexity:
Saleor.

If you anticipate lots of bespoke B2B/pricing/order workflows and want everything strongly typed:
Vendure.

One caveat: I wouldn't select based on benchmark claims like "X handles 10× more requests." For your architecture, the real scalability questions are checkout transactions/sec, cart concurrency, inventory contention, catalog size, search workload, cacheability, and database write volume. A CDN can make a storefront serving 100k requests/sec quite different from a checkout system doing 1k orders/sec.

If you give me your approximate traffic (requests/sec), orders/sec, SKU count, and whether you're B2C/B2B, I can narrow this to one and sketch the production architecture I'd use for a 10-person team.

For a 10-person startup building a high-traffic headless storefront, I would narrow the field aggressively. You probably do not want a traditional ecommerce suite (Magento/Adobe Commerce, WooCommerce, PrestaShop) unless you have a very specific reason. For a small engineering team, the winning criteria are:

• API-first/headless from day one
• strong caching and horizontal scaling story
• easy customization without forking core
• good TypeScript support (if your storefront is React/Next.js)
• manageable ops burden

The current open-source shortlist is mainly Medusa, Saleor, and Vendure. contracollective.comvendure.io

My default recommendation: Medusa

For a 10-person startup, I would start with Medusa unless you have unusually complex enterprise requirements. It is TypeScript/Node-based, modular, and designed around composable commerce workflows. contracollective.com

Why it fits a startup:

• Your team can likely keep the whole stack in TypeScript:
  • Next.js storefront
  • Node commerce backend
  • shared types/tooling
• Easier to hire for than Python/Django commerce stacks
• You can replace pieces (inventory, payments, fulfillment, pricing) instead of fighting a monolith
• Good fit for custom UX and nonstandard buying flows contracollective.com

Potential issues:

• You will own more commerce logic than with a mature enterprise suite
• Very complex inventory/warehouse scenarios may require more engineering
• You need to build strong operational practices (observability, queues, backups, deployment)

For a startup, I would rather spend engineering time building your differentiation than maintaining a giant commerce platform.

Strong alternative: Saleor

Pick Saleor if your business looks more like:

• international commerce
• many currencies
• many warehouses
• complex catalogs
• marketplace-like inventory
• enterprise customers

Saleor is GraphQL-first and has a strong data model for channels, regions, and complex catalogs. contracollective.com

Tradeoffs:

• Python/Django stack
• more opinionated architecture
• potentially less natural if your team is all-in on TypeScript

I would choose Saleor over Medusa if your biggest problem is commerce complexity, not product iteration speed.

Worth considering: Vendure

Vendure is a good option if your team likes TypeScript and wants a very structured plugin architecture. It is built around NestJS patterns and has a strong GraphQL approach. contracollective.comvendure.io

I would look at it for:

• B2B commerce
• complex pricing rules
• multi-channel systems
• teams that value strict architecture

The ecosystem is smaller than Medusa's, which matters for a small team trying to move quickly. contracollective.comvendure.io

My ranking for your situation

Architecture I would probably build

For a high-traffic startup:

Next.js storefront
        |
        |
Commerce API (Medusa/Saleor/Vendure)
        |
        +-- PostgreSQL
        +-- Redis
        +-- Search (OpenSearch/Algolia/Meilisearch)
        +-- Queue workers
        +-- CDN
        +-- Payment provider
        +-- ERP/WMS integrations

Do not let the ecommerce backend handle everything. At scale, keep:

• search outside the commerce database
• recommendations/personalization separate
• CMS separate
• analytics/event pipelines separate

The commerce engine should be the source of truth for:

• products
• prices
• carts
• orders
• inventory state

If you tell me:

1. expected GMV/orders per day,
2. catalog size (SKUs/variants),
3. DTC vs B2B vs marketplace,
4. your stack (Next.js? TypeScript? Python?),

I’d probably narrow this to one choice.
