Open-source eBay 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.

Bagisto is an open-source eCommerce and multi-vendor marketplace platform built on Laravel and Vue.js. It provides a flexible, customizable foundation for launching online stores, B2B commerce portals and marketplaces, and aims to cut the time and cost of development while leaving room to customize and scale.

The project's description claims support for catalogs of ten million or more SKUs, and its topics mention headless commerce, multi-tenancy and use as a Laravel package or framework. It is written in PHP and suits agencies and in-house teams that already know Laravel. The repository links to documentation, an installation guide, a Docker installation path and community forums, and the 2.x line was in beta at the time of writing.

Bagisto is MIT licensed, so you can host it on your own servers and modify it freely. It is a fit for merchants who prefer an open codebase over a hosted store builder, and for developers building custom commerce experiences who want Laravel conventions rather than a proprietary platform.

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.

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.

Mercur is an open-source, headless platform for building multi-vendor marketplaces and is presented as an alternative to Mirakl. It adds vendor onboarding, multi-vendor catalogs, offers, commissions, and automated payouts on top of a commerce core. The topics point to Medusa as that core. It is written in TypeScript and released under the MIT license.

The platform supports B2C, B2B, and hybrid marketplaces and includes a storefront, a vendor panel, an admin console, and integrations. The README stresses ownership: you self-host on your own infrastructure with full source access, and there is no percentage of gross merchandise value, no per-transaction fee, and no vendor lock-in.

Documentation, a live demo, and a Discord community are available. Mercur suits teams launching a marketplace who want to avoid both a revenue-sharing SaaS platform and a from-scratch build, and who have the engineering capacity to operate and customize the system.

GrandNode is an open-source e-commerce platform built with ASP.NET Core and MongoDB. Its use of a NoSQL database is the main design choice, aimed at fast page rendering and the ability to handle traffic spikes, and it targets businesses that want a customizable shop with room to grow.

The platform supports several business models, including B2B, B2C, multi-store, multi-vendor, multi-tenant, multi-language and multi-currency setups, so one installation can run several storefronts. It is designed to integrate with existing third-party software, and the project provides themes, plugins and integrations, a forum and a demo store. Premium support is offered separately by the maintainers.

GrandNode is written in C# on .NET and released under the GPL-3.0 licence. You can install it from the documented steps, build from source or run it locally, and host it on your own servers. It suits development teams and merchants in the .NET ecosystem who prefer MongoDB over a relational database for their store.

Shuup is an e-commerce platform built in Python on the Django framework, aimed at businesses that need either a conventional single-vendor online store or a multivendor marketplace where several sellers operate on the same storefront. It is positioned as a flexible, customizable foundation rather than a fixed, one-size-fits-all storefront.

Being built on Django, it benefits from Django's mature ecosystem for authentication, admin tooling and database management, and its topics indicate dedicated support for multivendor commerce scenarios, where a single platform instance can host multiple independent sellers. Further feature specifics were not available from the project's homepage at the time of this summary, so refer to the GitHub repository and documentation for details.

Shuup is written in Python with Django and the repository metadata lists its license as Other, so check the license file before relying on it for a commercial deployment. As a self-hosted Django application, it is deployed on infrastructure the operator controls.
