Medusa is an open-source commerce platform for developers, built with TypeScript and Node.js. Rather than a ready-made shop, it provides commerce modules, an admin dashboard and a framework for custom builds. Modules cover product management, inventory across several warehouses, multiple sales channels, regions with their own currencies and tax rules, and promotions including B2B pricing. It can support B2B or direct-to-consumer stores, marketplaces and point-of-sale. Teams can self-host the software or use Medusa Cloud, a managed service that runs the backend, admin, database and Redis and deploys from a GitHub repository.
The core is MIT-licensed and published on GitHub; some enterprise features fall under a separate commercial licence from MedusaJS, Inc. A third-party platform guide places the company in Copenhagen, Denmark, while Medusa's own pages state no headquarters. Self-hosting lets a European organisation choose its own infrastructure and jurisdiction. The Medusa Cloud documentation does not name hosting regions or the cloud provider, so confirm these with Medusa before relying on the managed service for EU-only processing.
