Open-source SAP Commerce Cloud alternatives

Medusa is an open-source commerce platform that includes its own framework for customizing behavior. Rather than a fixed storefront product, it supplies foundational commerce building blocks, so developers can assemble custom commerce applications without reinventing core logic such as carts, orders and payments.

The framework and modules can power advanced B2B or direct-to-consumer stores, marketplaces, distributor platforms, point-of-sale systems and service businesses. Its core commerce modules are open source and published on npm, while Enterprise Edition features are marked separately in the repository. It is written in TypeScript on Node.js, and its topics mention AI coding tools alongside the standard e-commerce stack. Release notes and an integrations catalog help teams keep a project current and connected to payment, shipping and other services.

For hosting, Medusa Cloud is a managed environment tuned for Medusa apps with automated deployments, scaling and maintenance, and you can also run the code locally or on your own servers by following the documentation. The license is listed as 'Other', so review which components are covered by which terms.

Saleor Core is an open-source headless commerce platform written in Python. It is API-only and GraphQL-native, so storefronts, dashboards and other clients talk to the backend exclusively through its API, which makes it a building block for composable commerce rather than a monolithic store application.

The project highlights several design choices: technology-agnostic, with no monolithic plugin system or lock-in; GraphQL only rather than a mix of API styles; open source with a single version and no feature fragmentation; cloud native; and native multichannel, with per-channel control over pricing, currencies, stock and products. Extension happens through webhooks and apps instead of modifying core code. Topics also mention product information management and order management.

Saleor is BSD-3-Clause licensed. The wider platform includes a separate dashboard and a storefront, and the README links documentation and community channels. You can self-host the core or use the vendor's cloud offering, and it suits engineering teams building custom shops, marketplaces and multi-country commerce experiences.

Spree is an open-source commerce platform written in Ruby. It bundles a full REST API, TypeScript SDKs, an admin dashboard written in React and a Next.js storefront ready for production, and the BSD 3-Clause license means you keep ownership of your code, data and infrastructure. The project's pitch is self-hosting with no platform fees and no vendor lock-in.

It is designed as a set of commerce primitives that adapt to different business models. For multi-vendor marketplaces it offers seller onboarding with configurable checklists, orders split by seller, commission rules, a payout ledger that uses Stripe Connect, and a dedicated seller panel. For B2B and wholesale it covers tiered volume pricing in price lists, customer groups, company accounts that have several locations, contacts, tax exemptions, and separate catalogs per segment. It also supports headless direct-to-consumer, cross-border and omnichannel selling alongside existing ERP, PIM and payment systems.

Spree has been developed since 2008, with documentation, an API reference, a roadmap and a Discord community. It suits engineering teams that want an owned, customizable commerce backend rather than a hosted store builder.

Magento Open Source is a PHP-based ecommerce platform used to build an online store from the ground up. The repository is magento/magento2, and the README presents it as software with the basic ecommerce capabilities, while directing merchants who need a more complete solution to Adobe Commerce.

Adobe Commerce adds an optimized cloud architecture with hosting, along with AI-powered merchandising and analytics, so the open-source edition is the self-managed starting point. The project has a large contributor community, with community maintainers who can review and merge pull requests, and the documentation covers system requirements, prerequisites and several installation options.

Magento is licensed under OSL-3.0, and contributors must sign the Adobe Contributor License Agreement. It runs on your own servers and fits developers, agencies and merchants who want control over the code of their store and are comfortable with the PHP ecosystem. Because it is a full platform, hosting, security updates and extensions are the store owner's responsibility.

Sylius is an open-source ecommerce framework built on Symfony, described as headless and based on PHP, Symfony and API Platform. It targets developers who need an online store tailored to specific business requirements rather than a fixed, off-the-shelf shop.

The code base is developed with full-stack behavior-driven development, using PHPUnit and Behat, and the project stresses code quality and testing culture. A REST API makes it possible to integrate the store with other systems and build customer experiences on any device. Installation is done through Composer, documentation lives at docs.sylius.com, and community support is available through Slack and Stack Overflow.

Sylius is licensed under MIT. The company also sells Sylius Plus, a commercial edition with modular features such as one-page checkout, a B2B suite, multi-store management, partial order fulfillment, returns handling, loyalty features and inventory spanning multiple sources, along with SLA-backed support. Plugins are available from the Sylius Store marketplace.

Vendure is a headless commerce platform, released as open source and written in TypeScript. Its backend uses Node.js, NestJS and GraphQL, and its admin dashboard is built with React and TanStack, so a team works in one language across the stack. It is plugin-first, so most behavior can be changed without forking the core.

One backend models catalog, orders, pricing, promotions and customers, and serves any frontend through a GraphQL API for D2C, B2B, marketplace and omnichannel scenarios. Built-in building blocks cover the catalog, orders, customers, promotions, sales channels, tax, shipping, payments and stock levels. Stable plugin contracts and service overrides allow custom entities, pricing logic and workflows. The introspectable GraphQL schema is described as straightforward to connect to LLM tool-calling, MCP servers and agent frameworks.

New projects are scaffolded with a command that sets up the server, admin dashboard and GraphQL API, and they require a current Node.js release (20.19 or 22.12) plus a SQL database such as PostgreSQL, MySQL, MariaDB or SQLite. The repository lists the licence as Other, so check the licence terms before commercial use.

Pimcore is an open core platform built for Product Experience Management. It offers an API-driven base for handling digital data and the customer experience, pairing a core framework with a modular set of extensions for product information management, master data management, digital asset management, customer data platform, a digital experience platform with CMS, and digital commerce.

A central idea is to keep data separate from any channel and send it to any destination, such as websites, apps, print or marketplaces. The code is PHP, and the project links to documentation, a live demo, a discussion forum and issue tracker. The README states that everything is licensed under the Pimcore Open Core License, shown as 'Other' on GitHub, so read it to see what the free core and extensions include.

Pimcore is self-hosted on your own infrastructure, with commercial support and cloud services available from the vendor. It suits mid-sized and larger organizations that need a single source of truth for product and content data across channels.

Shopware 6 is an open-source e-commerce platform written in PHP on top of the Symfony framework, with a Vue.js administration interface. It gives merchants, agencies, and developers a foundation for running online shops, from a conventional storefront to a headless setup in which a separate front end talks to the platform through its API.

The platform is API-first, so catalog, cart, and checkout functions can be consumed by custom storefronts, apps, or other business systems. Built-in experience-management tools let content teams assemble shopping pages, and a large extension store of community and commercial add-ons extends shop behavior without changing the core. Developers can build their own plugins and customize themes.

The code is published under the MIT license and can be self-hosted on a standard PHP and database stack, which suits agencies delivering custom shops and merchants who want control over their commerce stack. It competes in the same space as Magento and PrestaShop, both of which appear among the project's topics.

Aimeos is an integrated online shop for Laravel built on the Aimeos e-commerce framework. It is positioned as an API-first, cloud-native platform for fast online shops, scalable marketplaces, and complex B2B applications, and can be installed in a few minutes. It is written in PHP with a Vue-based admin and released under the MIT license.

Features include a JSON REST API following the jsonapi.org specification and a GraphQL API for administration, multi-vendor, multi-channel, and multi-warehouse operation, and support for multi-tenant SaaS e-commerce with unlimited vendors. Product types cover bundles, vouchers, virtual and configurable products, and custom or event products. Subscriptions with recurring payments and many payment options are supported, and the SEO-friendly design is among the topics.

The README describes it as a fit for AWS, Google, Azure, and Kubernetes environments, scaling from a handful of items to very large catalogs. Aimeos suits PHP and Laravel developers, agencies, and companies that want an extensible shop they can customize and host themselves.

Virto Commerce is an open-source platform for building extensible e-commerce applications. It targets complex digital commerce for B2B, B2C and B2B2C businesses, marketplaces and derived SaaS commerce platforms, and its architecture is based on microservices, an API-first approach, cloud-native delivery and headless operation.

The platform is assembled from ready-made modules, with every application made of headless microservices that can also be reused in other applications. Business logic is available through REST or GraphQL APIs, and the API model, persistence model and business logic can be extended. The README describes cloud-native delivery in line with a SaaS model, with on-demand use, scalability and reliability across data centers.

The code base is written in C# with an Angular admin interface and is associated with Microsoft Azure. The repository lists its licence as other, so check the terms before use. The project positions itself as letting development teams concentrate on business features rather than architecture. It suits enterprise teams and agencies that need a configurable, headless B2B commerce backend on the Microsoft stack.
