Editorial context
Why this app exists
To provide a fast desktop API client without cloud lock-in while covering modern protocols and fitting naturally into local files, Git, and agent workflows.
CurioBeam’s view
Why we like it
Strong privacy defaults, current cross-platform releases, indie sustainability, and a very clear Postman/Insomnia/Bruno comparison position make it commercially relevant to CurioBeam.
Product fit
Is it a fit?
Good for
- Developers who want a private, fast API client with HTTP, GraphQL, gRPC, WebSocket, SSE, Git sync, and CLI/agent integration.
Probably not for you if
