Cons of Medusa

  • Limited number of plugins: Medusa has a limited number of plugins available, compared to some other e-commerce platforms. This means that developers may need to build custom plugins to implement certain features.

Tech stack: Developer-friendly and high-performance

Medusa’s tech stack is designed with developers in mind, making it accessible and efficient. Here are some key components of Medusa’s tech stack:

Node.js Backend

Medusa’s core package, @medusajs/medusa, is a Node.js backend built on top of Express. It provides a solid foundation for your e-commerce project.

React storefront

Easily connect your React storefront or admin to Medusa’s backend using a range of convenient utilities, hooks, and contexts.

Database integration

It seamlessly connects to databases like PostgreSQL to store your e-commerce store’s data. It leverages TypeORM to represent database tables as entities, simplifying data management. Entities can be also reflected in the database using Migrations.


The backend exposes endpoints as REST APIs, enabling smooth communication between frontends and the backend. You can easily integrate Medusa with your custom frontend or admin dashboard.
You have multiple options for sending requests to these API Routes, such as:

Events architecture

Medusa employs an events architecture that triggers and handles events like order placements. It connects to a service, such as Redis, to manage event handling through a pub/sub model. 

Events can be managed through Subscribers, which are TypeScript or JavaScript classes that include methods as handlers for particular events. 


Medusa’s architecture emphasizes modularity. You can customize various aspects of your e-commerce setup, including entities, endpoints, services, and more, without modifying the core backend. Custom resources can be integrated seamlessly using loaders.


Medusa allows you to package your customizations into plugins, promoting reusability across different Medusa backends. You can also share your plugins with the community or use existing ones to enhance your e-commerce functionality.

Community & contributions

Medusa boasts an active and thriving community. You can seek support, discuss the roadmap, and share ideas on GitHub Discussions. If you’re interested in contributing to the codebase or documentation, Medusa provides a Contribution Guide to get you started. Additionally, you can join the community on Discord to connect with other enthusiasts.
