Hoppscotch
Open Source API Testing Tool for Fast Development

What are Hoppscotch and Thunder Client?
Hoppscotch is an API development environment that runs in your web browser. You can test any API by sending requests and viewing the responses instantly. Unlike traditional tools, Hoppscotch is completely free and open-source, meaning anyone can use it or even contribute to improving it.
The platform supports various API types including REST, GraphQL, WebSocket, Socket.IO, MQTT, and Server-Sent Events. This makes it useful for testing modern real-time applications as well as standard web services. You can organize your API requests into collections, use environment variables for different setups, and write tests to check if APIs work correctly.
Hoppscotch offers both a free version with full features and an Organization plan for teams needing extra collaboration tools and support.
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.
