5 Open Source E-commerce Platforms for Developers

For frontend engineers building a headless storefront in 2026, the strongest open-source commerce backends to evaluate are Medusa, Saleor, Vendure, Sylius, and Shopware. Each is API-first, actively maintained, and pairs cleanly with a Next.js or other React-based storefront — but they differ sharply in language runtime, API shape (REST vs GraphQL), licensing model, and the operational weight you take on when self-hosting. This article exists to help you shortlist one for a build you’re about to commit weeks of integration work and years of maintenance to.

WooCommerce, Magento, and PrestaShop deserve an honest acknowledgement here: they’re mature, widely deployed ecosystems with vast plugin marketplaces and merchant tooling that the platforms below haven’t matched. But their center of gravity is the WordPress/admin-template world, not API-driven storefronts written in TypeScript. If your storefront is a Next.js app calling a typed SDK or a GraphQL endpoint, the five platforms below are the relevant shortlist. If your storefront is a themed CMS site administered by a marketing team, you’re reading the wrong article.

Headless commerce is no longer a trend to be sold — it’s the default architecture for greenfield storefronts at this point. The question isn’t whether to decouple the storefront from the commerce engine, but which engine gives you the best developer experience for the years of feature work that follow.

How to choose: a comparison table

The fastest way to narrow a shortlist is to lay the platforms side by side on the dimensions a storefront developer actually cares about. The table below summarizes the five candidates; star counts and release versions move constantly, so treat them as a starting point and verify against each project’s GitHub releases page before you commit.

Two columns are worth lingering on. The license column doesn’t tell the whole story: Vendure and Shopware both ship an MIT-licensed core that is fully production-capable, alongside separately licensed commercial managed-platform offerings. That’s a feature for evaluation budgeting, not a trick — the open-source core is genuinely usable without paying for the platform tier. The self-hosting footprint column reflects the minimum services you’ll be operating in production, and it’s where Saleor diverges meaningfully from the Node-based options.

Medusa — Node.js/TypeScript headless commerce with v2 modules and workflows

Medusa is a Node.js/TypeScript headless commerce backend whose v2 release restructured the platform around independent commerce modules — products, cart, orders, inventory, pricing — each of which can be swapped for a custom implementation or a third-party service. See the official v2 documentation for the module and workflow architecture.

For a frontend engineer the result is the most composable of the five platforms here. Storefront code talks to the Medusa server via a typed JavaScript client; backend customization happens by writing modules and workflows in TypeScript that live in the same monorepo as the rest of your team’s services if you want. The official Next.js starter on the Medusa docs gets you a working storefront with cart, checkout, and account flows in a single create-medusa-app command.

Where Medusa stands out:

• Type-aligned end to end. The server is TypeScript; the storefront SDK is TypeScript; custom modules are TypeScript. There is no codegen step between schemas and storefront types.
• Workflows. Medusa v2 exposes an explicit workflow primitive for multi-step commerce operations (place order, return, etc.), which makes long-running and compensatable logic easier to reason about than implicit transaction chains.
• Local dev is straightforward. A single Node process against PostgreSQL, plus Redis for background jobs.

Where Medusa demands attention:

• REST-first. Medusa’s primary API is REST. Storefronts that want a single GraphQL endpoint and codegen-driven types will find Saleor more natural.
• v1 → v2 migration. Codebases still on Medusa v1 face non-trivial migration work; the module system, admin, and APIs all changed substantially.

Pick Medusa if your team is TypeScript-native, you want full ownership of customization in your own language, and a REST + typed-SDK ergonomic suits you. Skip Medusa if you want a GraphQL-only data layer or you need a deep, off-the-shelf admin and merchandising toolset on day one.

Saleor — GraphQL-first headless commerce on Python/Django

Saleor is a Python/Django headless commerce platform with a GraphQL-first API. Every commerce operation — product queries, checkout mutations, order management, customer accounts — runs through a single versioned GraphQL endpoint, documented in the Saleor API reference. The codebase is BSD-3-Clause licensed; see the LICENSE file on GitHub.

The GraphQL-first design matters most at the storefront layer. A Next.js storefront can co-locate its data requirements with its components using urql, Apollo, or graphql-request, run graphql-codegen against Saleor’s schema, and get fully typed query and mutation hooks without writing a separate REST adapter layer. A typical product page query looks like:

query ProductBySlug($slug: String!, $channel: String!) {
  product(slug: $slug, channel: $channel) {
    id
    name
    slug
    description
    variants {
      id
      name
      quantityAvailable
    }
  }
}

That single query returns exactly what the page renders — no overfetching, no separate inventory call, no price-formatting helper that drifts from the server’s idea of currency. Saleor also publishes an official Next.js storefront example (storefront repo) you can fork rather than build from scratch.

Where Saleor demands attention:

• Operational footprint. Saleor self-hosted needs Python, PostgreSQL, Redis, and a Celery worker process for async tasks. That’s heavier than a Node + Postgres combination and worth knowing if your team isn’t already running a Python stack.
• Schema versioning discipline. A GraphQL-first platform means breaking schema changes are visible. Saleor releases new minor versions with clear migration notes, but storefronts that don’t pin the schema and regenerate types will hit silent breakages after upgrades.

Pick Saleor if you want a single GraphQL endpoint, you’re comfortable running a Python stack, and your storefront team is fluent in GraphQL clients and codegen. Skip Saleor if your team has no Python operational experience and you’d rather keep the entire stack on Node.

Vendure — TypeScript/NestJS framework with MIT Core and a commercial Platform tier

Vendure is a TypeScript/NestJS headless commerce framework with a GraphQL API and an Angular-based admin. It is the only platform in this comparison that ships its plugin API, service layer, and GraphQL schema extensions in TypeScript with full type inference — meaning custom plugins and storefront code share a single language and type model. The Vendure documentation covers the plugin system, the dual Shop/Admin GraphQL APIs, and the data model.

Vendure’s open-source Core (MIT-licensed) is a fully functional headless commerce engine. The commercial Vendure Platform adds managed hosting, enterprise support, and additional modules, but is not required to run a production storefront. This separation is worth understanding before you adopt: the Core is genuinely complete, and “open source” doesn’t mean “feature-limited demo.”

From the storefront perspective Vendure exposes two GraphQL APIs — Shop for public storefront operations and Admin for back-office tooling. Both are introspected and codegen-friendly. NestJS underpins the server, which means custom plugins follow a familiar module-provider pattern if your team has any NestJS background.

Where Vendure shines:

• TypeScript everywhere. Server, plugins, admin UI extensions, and storefront — one type system.
• Clean plugin architecture. Custom fields, lifecycle hooks, and GraphQL schema extensions are first-class, not bolted on.
• Lightweight self-hosting. Single Node process against PostgreSQL or MySQL. The default getting-started flow uses SQLite for local dev.

Where Vendure trades off:

• Smaller ecosystem. Compared to Saleor or Medusa, the third-party plugin and integration catalog is smaller. You’ll write more glue code yourself.
• Admin is Angular. If your team plans to heavily customize the admin UI and is React-only, that’s a context-switch tax.

Pick Vendure if you want the most TypeScript-native, type-safe headless commerce stack available and you’re willing to build some integrations yourself. Skip Vendure if you need the broadest plugin marketplace on day one or you can’t tolerate an Angular admin.

Sylius — Symfony commerce framework with REST and GraphQL via API Platform

Sylius is an open-source ecommerce framework built on Symfony (PHP). It is positioned as a framework rather than a turnkey platform: it provides the commerce primitives (products, channels, orders, promotions, carts) and assumes you’ll compose them into the application your business actually needs. The Sylius documentation covers the component model and the Symfony bundles.

For frontend engineers, Sylius matters because of its API layer. Sylius integrates with API Platform to expose REST and GraphQL endpoints over its data model, which makes it usable as a headless backend for a Next.js or other JavaScript storefront. The default storefront uses Twig templates — fine for traditional builds, ignorable if you’re going headless.

Where Sylius wins:

• Symfony depth. If your organization is Symfony-fluent, Sylius slots into the broader PHP enterprise ecosystem more naturally than any other platform here.
• Customization through framework idioms. Override services, events, and entities using standard Symfony patterns. No proprietary plugin DSL.
• MIT license, no commercial tier required. The full Sylius codebase under MIT is what you build on.

Where Sylius trades off:

• PHP runtime. A Next.js team without PHP operational experience inherits PHP-FPM, Composer, and Symfony tooling for the backend.
• More assembly required. Sylius is honest about being a framework. You’ll write more code than you would with Medusa or Saleor to reach feature parity with a turnkey platform.

Pick Sylius if you have Symfony fluency in-house and you want a commerce framework you can shape entirely to your domain. Skip Sylius if your team is JS-only and you’d rather not run a PHP runtime alongside your Node services.

Shopware 6 — PHP/Symfony backend with deep merchant tooling and a Vue.js storefront

Shopware 6’s MIT-licensed Community Edition is a full-featured commerce backend with both traditional and headless deployment options, exposing a REST Store API alongside its Vue.js-based storefront framework. Commercial Rise, Evolve, and Beyond plans add managed hosting, advanced B2B capabilities, and enterprise support features, but the open-source core is production-capable without a commercial license. The Shopware developer documentation covers the Store API, Admin API, and app/plugin systems.

Shopware is the most merchant-feature-complete platform in this comparison. The “Shopping Experiences” CMS provides a drag-and-drop page builder for marketing pages; the rule builder supports dynamic pricing, shipping, and promotion rules without code; the admin tooling is genuinely deep. For a developer building a Next.js storefront, the Store API is REST-based and well-documented, and there are community Next.js storefront starters that consume it.

Where Shopware wins:

• Out-of-the-box merchant tooling that none of the developer-first platforms above match.
• Strong European market position with a mature partner ecosystem.
• Hybrid headless. You can run the default Vue.js storefront or go fully headless via Store API.

Where Shopware trades off:

• PHP + Elasticsearch operational footprint. Heavier to self-host than the Node options.
• Plugin system is PHP-centric. Backend customization is in PHP/Symfony, even if your storefront is TypeScript.

Pick Shopware if you need substantial merchant features out of the box and you’re comfortable operating a Symfony/PHP stack. Skip Shopware if your team is JS-only and you’d rather pick a lighter, more developer-first option like Medusa or Vendure.

When Spree makes sense instead

If Shopware feels too enterprise-oriented and your team has Ruby on Rails experience, Spree Commerce is a reasonable fallback. It’s MIT-licensed, fully API-driven, supports multi-store and multi-vendor setups, and has been around long enough that the Rails patterns are well-established. The tradeoff mirrors Sylius’s: Ruby on Rails instead of Symfony, but the same shape of decision — adopt a mature server-side framework’s ecosystem in exchange for a non-JS runtime.

Frontend-side decision factors

At the storefront integration layer, five factors decide whether a backend feels productive or painful: TypeScript ergonomics, Next.js compatibility, local-dev cold start, plugin architecture, and documentation depth.

TypeScript and codegen ergonomics. Medusa and Vendure both ship TypeScript SDKs that align with the server’s types without a separate generation step. Saleor’s GraphQL schema is best consumed through graphql-codegen, which adds a build step but produces excellent typed hooks. Sylius and Shopware require you to model API responses yourself or use community-generated clients.

Next.js compatibility. Medusa and Saleor both maintain official Next.js storefront examples that work with the App Router. Vendure has community starters. Sylius and Shopware are typically consumed by Next.js storefronts via direct API calls or community SDKs — workable, but you’re writing more of the integration yourself.

Local development experience. Medusa and Vendure offer the fastest cold start — install dependencies, run a migration, start the server, you’re done. Saleor is well-documented but heavier due to the Python + Redis + Celery requirement; Docker Compose is recommended. Shopware and Sylius assume a working PHP development environment; Docker images smooth this but the moving parts are more numerous.

Plugin and extension architecture. All five platforms support custom extensions, but the developer experience differs. Vendure plugins are TypeScript modules with type-safe lifecycle hooks. Medusa v2 modules are TypeScript classes with a clear contract. Saleor uses webhook-based “apps” that run as separate services — a stronger isolation boundary but more operational overhead. Sylius and Shopware use Symfony’s bundle/plugin systems.

Documentation quality. Across the five, Medusa, Saleor, Vendure, and Shopware all maintain documentation sites with API references, tutorials, and architecture overviews kept reasonably current with releases. Sylius’s documentation is thorough but assumes Symfony fluency.

Real-world failures that survive any platform choice

A common production failure mode in headless storefronts — across every backend in this article — is React hydration mismatch on product pages, where server-rendered prices, inventory counts, or localized strings diverge from what the client renders after fetching fresh data. Other recurring patterns: silent cart state divergence when the client cart and the server session drift apart after a network failure; payment provider scripts (Stripe, Adyen, PayPal) failing to load or initialize and surfacing only as a stuck checkout button; and breaking schema changes after a backend upgrade producing cryptic null fields rather than loud errors.

These failures are platform-agnostic but vary in debuggability depending on how the backend exposes error context in its API responses. Saleor’s GraphQL errors carry structured codes; Medusa’s REST responses include error types; Shopware and Sylius expose Symfony’s structured error format. Regardless of which you choose, instrumenting the storefront with session replay tooling like OpenReplay — to capture the actual DOM state, network requests, console errors, and user interactions leading to a failed cart or broken checkout — closes the loop between “user says checkout is broken” and a reproducible bug report. OpenReplay’s session-replay product is built specifically for this category of frontend production debugging.

Making the call

The shortlist collapses quickly once you weigh the team’s language fluency and the storefront’s data-layer preference. A TypeScript-native team building a Next.js storefront with a typed SDK should evaluate Medusa first and Vendure second. A team wanting a single GraphQL endpoint and willing to operate a Python stack should evaluate Saleor. A Symfony-fluent team should evaluate Sylius for a framework-shaped build or Shopware for the most complete merchant tooling. Run the local quickstart for your top one or two candidates before committing — an afternoon of docker-compose up and a tour of the admin will tell you more than another week of comparison reading.
