Medusa, widely known as MedusaJS, is an open-source headless commerce platform built for developers who want to build custom e-commerce, B2B, or marketplace applications without starting from scratch. Founded in 2021 in Copenhagen, Denmark, by Sebastian Rindom, Oliver Juhl, and Nicklas Gellner, the company raised an $8 million seed round in 2022 led by Dawn Capital.
The core platform is built on TypeScript and Node.js and released under the MIT License, making it free to self-host with no licensing fees, transaction fees, or gross-merchandise-value-based charges, distinguishing it from many commercial e-commerce platforms.
Medusa provides a modular commerce framework made up of composable building blocks, including product, cart, order, pricing, promotion, inventory, and fulfillment modules, that developers can combine and extend to support advanced B2B, direct-to-consumer, marketplace, or point-of-sale use cases.
Because it is API-first and headless, Medusa can power any frontend, custom storefronts, mobile apps, or even AI-driven commerce agents, without being tied to a specific presentation layer, giving development teams full control over the customer experience.
Medusa's core platform is free and open source under the MIT License, so teams can self-host it on their own infrastructure at no licensing cost.
For teams that prefer managed hosting, Medusa Cloud offers published plans starting with Develop from $29 per month, Launch from $99 per month, and Scale from $299 per month, plus a custom-priced Enterprise tier, with usage-based add-ons for compute, storage, data transfer, and additional seats.

Medusa Cloud is the official managed hosting service for Medusa, with published plans starting at $29 per month for the Develop tier, scaling up to a custom-priced Enterprise tier.
Medusa is a strong alternative for technical teams that need deep customization or headless architecture, whereas Shopify is generally easier for non-technical merchants who want an out-of-the-box store.
Medusa can be used to build custom storefronts, B2B commerce portals, multi-vendor marketplaces, point-of-sale systems, and other commerce applications on top of its modular framework.
