Insomnia
Kong Insomnia is an open-source, desktop-first platform that lets developers design, debug, test, and mock APIs - across REST, GraphQL, gRPC, WebSockets, SSE, and more - all within one intuitive application. It combines a clean, developer-focused interface with powerful features like authentication helpers, code-generation in multiple languages, environment variables, and custom plugin extensibility. It is designed to compete with Postman, offering a comprehensive library of features at only a fraction of the cost.
Insomnia empowers both solo coders and teams by offering local-first storage enhanced with Git sync and optional cloud sync equipped with end-to-end encryption for secure collaboration. Its Inso CLI brings the full power of Insomnia to your terminal and CI/CD workflows - running API tests, linting specs, exporting APIs, and more - streamlining automation in modern development pipelines.
