Postman
Complete API Development Platform for Testing & Collaboration

What are Thunder Client and Postman?
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.
Postman is an all-in-one platform for working with APIs throughout their entire lifecycle. It provides tools to send API requests, view responses, write tests, create documentation, and monitor performance. Unlike basic HTTP clients, Postman offers a complete environment where teams can organize their work into collections, share them with teammates, and automate testing.
The platform includes an easy-to-use interface where you can build requests without writing code, though it also supports advanced scripting when needed. Postman works as a desktop app, web app, or through command-line tools for automation. It integrates with popular development tools and supports team collaboration through workspaces, making it ideal for both individual developers and large organizations building complex API systems.
