About Insomnia
Insomnia is an open-source API client that supports REST, GraphQL, gRPC, and WebSocket testing. Acquired by Kong, it offers the powerful features of Postman with an open-source core. Request chains automatically pass values between requests. Environments and variables work similarly to Postman. The free tier is fully functional for individuals. Inso CLI enables CI/CD integration for API testing. Compare to Postman (more features, more cloud-dependent), Bruno (completely local/offline). Best for: developers who want a capable open-source alternative to Postman with optional self-hosting.
