Unchained Engine
Headless e-commerce engine for Node.js, with a GraphQL API, an admin UI and a modular package set.
Unchained Engine is a modular, API-first e-commerce engine for Node.js, published as a monorepo of npm packages. Its docs describe it as a headless e-commerce SDK with a GraphQL API, and the README says it is embedded in the integrator’s own server process. Data is kept in MongoDB, and the admin UI is started locally on a port the README names. Access control comes from a role-based package, and OIDC login is shown in an example.
The packages cover the domains of an online shop: products, orders, users, payments, delivery, assortments, filters, warehousing, enrollments, quotations and files, with a core package that combines them.
