Insomnia is an open‑source, cross‑platform client that lets developers design, debug, test, mock, and collaborate on APIs supporting GraphQL, REST, WebSockets, SSE, gRPC, and other HTTP protocols. It’s aimed at engineers who need a powerful, offline‑first tool for managing API projects—whether they prefer to keep data locally, sync via their own Git repos, or collaborate in the cloud.
