SoapUI

SoapUI is a testing platform that checks how APIs and web services perform. You can use it to send requests to your API, check the responses, and make sure everything works as expected. It runs on Windows, Mac, and Linux computers because it is built using Java.

The tool lets you do functional testing to verify your API works correctly, load testing to see how it handles many users, and security testing to find weak points. You can also write custom test scripts using Groovy programming language for more complex scenarios.

SoapUI works well with popular tools like Jenkins for continuous testing in your development process. The open-source version is completely free, while ReadyAPI offers extra productivity features.
