Vendure

Vendure is a headless commerce platform for modeling catalog, orders, pricing, promotions and customers on a backend you can change at the core rather than work around. It's built end-to-end in TypeScript on NestJS, exposes a GraphQL API, and ships a React/TanStack-based admin dashboard. Its plugin system is the primary extension point — most custom business logic is expected to be written as plugins rather than forked core code.

It supports single-store and multi-channel setups (useful for running D2C and B2B storefronts, or multiple regional storefronts, from one backend), and is commonly paired with a separate frontend framework since it's headless by design.

Vendure is dual-licensed: the open source edition is GPLv3, with a separate commercial license (Vendure Commercial License) available from Vendure GmbH for teams that need different terms. Worth knowing before adopting it, since that's a different model from the fully permissive licenses on some other platforms in this catalog.
