Overview
What we do, and why it matters
MedusaJS suits teams that want to own their commerce stack in TypeScript and compose it from modules rather than fight a monolith. We build Medusa backends and custom modules, connect payment, fulfillment, and search providers, and pair them with fast Next.js storefronts.
Headless means more moving parts and a storefront you own outright, so we're direct about the trade-offs. When a merchant is better served by Magento or Shopware, we say so.

FAQ
Frequently asked questions
What is MedusaJS?
MedusaJS is an open-source, headless commerce engine built in Node.js and TypeScript. It gives developers a composable backend to build custom storefronts and workflows against.
Do you build the storefront too?
Yes. We build custom Next.js/React storefronts against the Medusa API, not just the backend.
Is Medusa right for us, or should we stay on Magento?
Headless adds flexibility and moving parts. If you have the team and the need for a custom stack, Medusa is a strong choice; if you want a batteries-included platform, Magento may fit better.
Can you migrate our store to MedusaJS?
Yes. We migrate stores to a headless Medusa architecture with data and SEO planned up front, and we have written about migrating both to and from Medusa.
