Saleor

Saleor is a GraphQL-native e-commerce backend designed for brands building custom storefronts across web, mobile, and voice channels. The platform handles product catalogs, orders, payments, and fulfillment through a modern GraphQL API that keeps frontend and backend completely decoupled.

It works well for companies that need headless commerce without the complexity of monolithic platforms. Saleor's extensible plugin system lets teams customize business logic, and its open-source nature means you control the data and deployment.
