About Insomnia
Insomnia is a clean, quick API client that many developers prefer to heavier platforms. You can send requests to REST, GraphQL, gRPC and WebSocket endpoints, organize them into collections and write tests.
It is maintained by Kong, and newer versions add AI features such as generating mock servers, writing test scripts and helping with commit messages for your API files. Data can stay local or sync through Git, depending on your team's preferences.
The core app is open source and free, with paid plans for team sync and extra features. It is a good pick for developers who want something light and flexible.
