Spree Commerce

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.
