Facts checked 8 Oct 2026

In short

The Essentials plan is free; Pro costs $10 per user a month billed annually, or $12 billed monthly¹.
Request screens cover GraphQL, gRPC, WebSocket and SSE clients^1,12.
A local Scratch Pad works before you log in, and Git Sync stores projects as YAML files in your repository^4,5.
Source code is on GitHub under Apache-2.0¹⁰.
Single sign-on (SAML 2.0 and OIDC) needs the Enterprise plan⁶.

Insomnia suits people who want an open-source client that can run without an account and keep projects as YAML files in Git^4,5,10. Pro at $10 per user a month, billed annually, adds Git Sync for every user and larger mock limits¹. The catch: Git Sync is free for only 3 users, there is no web app, and the pricing page names SOC2 without saying Type II¹.

Best for: People who want an open-source client with GraphQL, gRPC, WebSocket and SSE screens.
