What Unchained Engine is

Unchained Engine is a free, open-source headless e-commerce platform built with Node.js and GraphQL. By separating the frontend from the backend, it can power web, mobile, IoT, and social commerce from one backend, and is described for uses ranging from simple stores to complex B2B marketplaces. Commerce modules cover product catalogs, orders, payments, delivery, warehousing, and role-based user authentication. Developers get a GraphQL API, TypeScript support, a built-in playground, hot module reloading, and a plugin system. Listed integrations include Stripe, PayPal, Datatrans, SendGrid, Mailchimp, Twilio, DHL, UPS, AWS S3, Google Cloud, and Cloudinary. Security features include WebAuthn/passkeys, encrypted sessions, role-based access control, and payment tokenization that keeps card data off the platform servers. The platform can be self-hosted and is Docker-ready for Docker or Kubernetes environments. It is free under EUPL terms without licensing or per-transaction fees, though users pay for hosting infrastructure; distributed modifications must use compatible open-source terms.
