Things people build with this

USE CASE 1

Build a realistic frontend portfolio project by connecting it to a ready-made API without writing any backend code.

USE CASE 2

Practice fetching data, sending POST requests, and handling authentication flows using realistic endpoints.

USE CASE 3

Deploy your own private copy to Railway so your test data persists instead of being wiped every two hours.

USE CASE 4

Contribute a new API endpoint to the project and add it to your open-source portfolio.

In plain English

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.

Copy-paste prompts

Prompt 1
Show me how to run FreeAPI.app locally with Docker so I have a stable backend for my React project that doesn't reset every two hours like the public server.
Prompt 2
List all the available FreeAPI.app endpoints and give me a JavaScript fetch example for each category, users, products, and any social-media-style endpoints.
Prompt 3
I'm building a portfolio e-commerce app in React, write the code to fetch a product list from FreeAPI.app, display it in a grid, and add a shopping cart using the API's cart endpoints.
Prompt 4
How do I deploy my own copy of FreeAPI.app to Railway using the one-click template, and what environment variables do I need to set for MongoDB to work?
Prompt 5
Write a Node.js script that tests all the user authentication endpoints in FreeAPI.app, register, login, refresh token, and logout, and prints pass or fail for each one.
