What are SoapUI and Thunder Client?

SoapUI logo
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.

Thunder Client

Thunder Client is a REST API testing tool that lives inside Visual Studio Code. You can send requests, check responses, and organize your API tests without opening another program. It works just like other API testing tools but runs directly in your code editor.

The extension saves all your requests and settings on your own computer. This makes it fast, private, and able to work without internet. You can also save your testing data to Git repositories, making it easy to share with your team.

Thunder Client offers both free and paid versions. The free version works great for basic testing, while paid plans add features like unlimited test runs, team management tools, and advanced testing options for businesses.
