FreeAPI.app is an open-source collection of practice APIs designed to help developers learn how to work with APIs when building web or mobile apps. The idea is that beginners and students often struggle to find realistic API data to build frontend projects against, so this project provides a ready-made backend they can connect to without needing to set up their own database or write server-side code from scratch.

The project offers a range of endpoints covering different domains, from simple beginner-friendly responses to more complex scenarios useful for building portfolio projects. You can use it to practice fetching data, sending requests, handling responses, and building complete apps with real-looking data.

There is a publicly hosted version of the API, but the README warns that the server is reset every two hours to avoid hosting costs, which wipes all uploaded files and user data. For any serious development work, the recommended approach is to run it locally by cloning the repository, or to deploy your own copy to a service like Railway using a one-click template the project provides.

Running it locally requires Node.js and MongoDB. The project also supports Docker, which bundles everything together so you do not have to install MongoDB separately. Once running, the API is accessible at local endpoints you can point your frontend code at.

The project is maintained by Hitesh Choudhary, who creates programming tutorials for a large online audience. The repository is community-driven, and the README encourages contributors to add new API endpoints. It is aimed squarely at learners who want to practice API integration in any programming language without worrying about the backend side of things.
