About Insomnia
Insomnia is an open-source, cross-platform API client for GraphQL, REST, WebSockets, Server-Sent Events, gRPC and any other HTTP-compatible protocol. It lets you debug, design, test and mock APIs in one app.
Projects can be kept in a fully local vault, synced through a Git repository you choose, or shared through cloud sync with optional end-to-end encryption. A native CLI supports linting and testing in CI/CD pipelines, and third-party plugins extend the app.
Highlights
- Debug requests across REST, GraphQL, WebSockets, SSE and gRPC
- Native OpenAPI editor with visual preview
- Test suites and a collection runner
- Mocking through a cloud or self-hosted mock server
- Local Vault, Git Sync and Cloud Sync storage options
- Insomnia CLI for linting and testing in CI/CD
