Medusa is a headless commerce engine designed as a modular, API-first platform for building custom digital storefronts and business applications. Its architecture is built on a decoupled system where core business logic is encapsulated into independent, swappable modules that communicate through defined interfaces, allowing developers to incrementally adopt or replace components to fit specific operational needs.
The platform distinguishes itself through a highly extensible design that supports complex commerce requirements, including multi-vendor marketplace operations, B2B purchasing workflows, and multi-location inventory management. It provides a service-oriented API layer and a flexible administrative interface that allows for the injection of custom views and tools, ensuring that the management experience can be tailored to unique business processes.
Beyond its core commerce capabilities, the platform includes a comprehensive suite of features for managing the entire order lifecycle, product catalogs, and dynamic pricing rules. It integrates with a wide range of third-party services for payments, logistics, and content management, while offering built-in support for transactional emails, API caching, and multi-tenant resource isolation.
Developers can accelerate project initialization using pre-built starters and managed cloud deployment pipelines. The platform also provides specialized command-line tooling and AI-assisted development agents to streamline infrastructure management, debugging, and deployment workflows.
