Hoppscotch

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.

Getting started with Hoppscotch is straightforward. Here are the key steps:

• Visit the website at hoppscotch.io and start immediately without creating an account. For saving your work, sign in using GitHub, Google, or Microsoft.

• Choose your API type from the menu - REST for standard APIs, GraphQL for graph-based queries, or WebSocket for real-time connections.

• Enter your API endpoint URL in the address bar, select the request method like GET or POST, and add any headers or body data needed.

• Click Send and view the response instantly. The platform shows you the data, headers, and timing information.

• Save your requests into collections for easy access later. Use environment variables to switch between development and production settings.

• Install the desktop app or browser extension if you need offline access or want to handle local APIs without network restrictions.
