MedusaJs

An open source headless commerce platform for building custom digital storefronts, with a Node.js backend.

About MedusaJs

MedusaJs is an open source, headless commerce engine that developers use to build custom online stores, marketplaces, and subscription services. Instead of forcing a predefined frontend, it provides a flexible backend with a set of APIs, leaving you in full control of the customer experience. You can integrate any frontend framework, from Next.js to React Native.

The platform ships with over two dozen modules for common commerce features: carts, products, orders, discounts, inventory, payments, and shipping. It supports multiple payment providers out of the box, including Stripe, PayPal, and Klarna. Medusa runs on Node.js and uses PostgreSQL as its database, with Redis for caching and queue management. The project is built by the Medusa team, formerly known as Medusa Commerce.

It is well suited for teams that need to customize deeply without being locked into a monolithic SaaS platform. MedusaJs is released under the MIT license, making it free to use and modify. The project has gained significant traction, with over 20,000 stars on GitHub and an active community contributing plugins and extensions.
