Firecamp
Open Source API Testing Platform for REST, GraphQL & WebSocket

What are Firecamp and Thunder Client?
Firecamp is a multi-protocol API development tool that helps you test and build APIs with ease. Unlike traditional API clients that focus mainly on REST, Firecamp offers dedicated GUI playgrounds for REST, GraphQL, WebSocket, and Socket.IO protocols all in one application.
The platform is completely open-source and built with developers in mind. It provides a clean interface similar to VS Code, making it familiar and easy to navigate. You can create API collections, set up environments, write scripts, and collaborate with your team in real-time.
Whether you use the web version or desktop app, Firecamp keeps everything synchronized across your workspace. It supports authentication methods, allows you to import collections from Postman, and helps you document your APIs for your team or community.
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.
