The world’s most popular API development and testing tool. Free tier supports unlimited requests, API documentation, mock servers, and team collaboration (up to 3 members).
Postman is a comprehensive API development tool. Send HTTP requests, manage environments, write tests, and generate documentation. The free tier is very capable, with unlimited requests, mock servers, and small‑team collaboration.
I use Postman to test backend endpoints, saving requests in collections and running them with the Runner. Mock servers let frontend development proceed before the real API is ready. Team sharing helps colleagues see my API docs.
Postman is a must‑have for backend developers. The free tier covers most daily needs.
Pro tip: Use Postman’s environment variables to switch between dev/test/prod without hardcoding URLs.
