Insomnia
Insomnia is a free, open-source API client for testing REST, GraphQL, gRPC, and WebSocket APIs with powerful team collaboration features.
What is Insomnia
Insomnia is a desktop application that lets you test and work with APIs. Think of it as a specialized tool for developers who need to send requests to APIs and check the responses they get back. It supports all major API types, so you don't need different tools for different projects.
The tool includes helpful features like environment variables (which let you switch between different settings easily), code generation (which creates code snippets you can use), and authentication helpers (which handle login details). You can also create mock servers to test your APIs before they're fully built.
Insomnia offers both free and paid versions. The free version works great for most individual developers, while paid plans add team features and extra tools.
How to Use Insomnia
Getting started with Insomnia is straightforward. Here's how to use it effectively:
Download and install Insomnia from the official website. It works on Mac, Windows, and Linux.
Create a new collection to organize your API requests. Collections help you group related requests together.
Add a new request by clicking the plus button. Choose your request type (GET, POST, etc.) and enter your API endpoint URL.
Set up environment variables for things like API keys or base URLs. This makes it easy to switch between development and production settings.
Use the Auth tab to set up authentication. Insomnia supports OAuth, API keys, bearer tokens, and other authentication methods.
Send your request and view the response. You can see the response body, headers, cookies, and timing information.
Create test suites to automate your API testing and ensure everything works correctly.
