Medusa

Medusa is an open source commerce platform for developers, positioned as a stack that can be built, customized and operated with the help of AI agents. It is a flexible backend and framework for online stores, with an admin dashboard and a set of commerce modules that teams extend with their own code. The commerce features include advanced product management with bundles and a bulk editor, multiple sales channels for multi store sales, point of sale and apps, inventory with multi warehouse support and order reservations, multi regional currencies and tax rules, and a promotion engine covering campaigns, B2B pricing and free shipping. The framework includes guardrails intended to let agents build customizations safely. The AI related tooling on Medusa Cloud covers an MCP server, a development agent, a Cloud CLI, skills and agent previews. Medusa Search, a built in search engine, was recently announced. Medusa suits engineering teams building B2C and B2B stores that need more flexibility than a hosted storefront product allows. Customer examples on the site include fulfillment across third party logistics providers, B2B ordering portals and ticketing. The software is free to self host. Medusa Cloud hosting is priced by plan: Develop from $29 per month, Launch from $99 per month, Scale from $299 per month, and a custom priced Enterprise plan. The vendor states there are no GMV fees or special licenses, and some add ons such as log drains carry separate monthly charges.
