Insomnia is an API client made by Kong for developers who design, test and debug APIs every day. Instead of juggling terminal commands and scattered notes, you build requests in a tidy workspace, save them in collections and run them again whenever you need. It suits solo developers and whole teams alike, whether you are checking a small local service or working through a large public API with many environments.

Key Features

• Send REST, GraphQL, gRPC and WebSocket requests from one app
• Organise work into collections, projects and reusable environments
• Manage cookies, headers and many common authentication methods
• Design APIs with OpenAPI specs and preview changes as you work
• Store data locally, sync with Git or collaborate in the cloud
