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.

Getting started with Thunder Client is straightforward. Here are the main steps:

• Install the extension from the VS Code marketplace by searching for Thunder Client. Click install and wait a few seconds.
