Show HN: Autonomo – AI developing while E2E testing

[sebringj]

Hey HN,

I built Autonomo MCP because AI coding agents (Cursor, Claude, etc.) are great at generating code but terrible at actually running and validating it in real apps. They hallucinate, rely on slow screenshots, or break on multi-device flows.

Autonomo MCP gives agents a fast (~50ms), structured JSON view of app state (semantic UI IDs, network calls, errors, logs) across web + iOS + Android + desktop simultaneously. Local-first, MCP-integrated, no cloud leaks.

- Swap vision bloat for tiny tokens - Cross-device validation (e.g. tap mobile → see web update) - Early stage, just launched: https://github.com/sebringj/autonomo

Would love feedback: Does this solve a pain point for anyone building agentic dev tools? What platforms/workflows would you want next? (Android/Kotlin and C#/.NET are on the TODO list.)

Thanks for any stars, comments, or tries!
