Medusa

Medusa is an open-source commerce platform with a built-in customization framework for building digital commerce applications without rebuilding core commerce logic. It gives developers foundational commerce primitives such as products, carts, orders, and payments to assemble into the exact store they need.

Those primitives ship as open-source commerce modules, freely available on npm, that snap onto a shared framework. The same foundation backs many shapes of store, from B2B and DTC stores to marketplaces, distributor platforms, point of sale, and service businesses, and the framework lets teams extend or replace logic rather than work around a fixed system.

Medusa can be self-hosted from the public core modules for local development and production. Medusa Cloud is an optional managed environment that handles automated deployments, scaling, and maintenance. The platform is licensed under the MIT License.
