Insomnia is an open-source, cross-platform desktop API client for debugging, designing, testing, and mocking APIs across REST, GraphQL, WebSockets, SSE, and gRPC. It supports local, Git, and cloud storage backends, an OpenAPI design editor, collection testing with scripting, mock servers, and a CLI (Inso) for CI/CD automation.
Use cases
- debug and send requests to REST, GraphQL, gRPC, and WebSocket APIs
- design APIs from OpenAPI specs with live preview
- run automated API test collections in CI/CD pipelines
- generate mock servers from OpenAPI specs or natural language
- test MCP servers with a native MCP client
- store API collections locally or sync via Git without cloud
- import Postman collections and scripts
When to choose
- you need a free, open-source Postman alternative with multi-protocol support
- you want local-only or Git-based storage for sensitive API collections
- your team follows a design-first OpenAPI workflow with linting and CI automation
- you need API mocking to unblock frontend/backend parallel development
When to avoid
- you only need simple one-off curl-style requests from the terminal
- you require fully offline use of premium features like unlimited collaboration or enterprise SSO
- you prefer a lightweight CLI-only HTTP client without a GUI
