Overview
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.
Key Features
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.
Pricing
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.
Key Features
Modular commerce framework — Provides composable modules for product, cart, order, pricing, promotion, inventory, and fulfillment logic that developers can extend.
Headless, API-first architecture — Decouples the commerce backend from the frontend, allowing any storefront, app, or AI agent to consume the same commerce API.
TypeScript and Node.js foundation — Built on a modern, widely-used JavaScript stack familiar to most web development teams.
B2B and marketplace support — Includes primitives for complex B2B commerce, multi-vendor marketplaces, and distributor platforms.
Open-source core with MIT license — The full platform is free to self-host with no license fees or per-transaction charges.
Medusa Cloud managed hosting — Offers an official managed hosting option with tiered plans for teams that do not want to operate their own infrastructure.
Extensible plugin and integration ecosystem — Supports plugins and integrations for payments, shipping, search, and other commerce services.
Point-of-sale and service commerce support — Modular architecture extends beyond typical online storefronts to POS and service-based business models.
