Launch Team / Built With
Hey Product Hunt! 👋
I built Farol after noticing a gap in the market — there were no lightweight, solo-dev-friendly monitoring tools for AI agents. Everything was either enterprise-grade overkill or required complex setup.
Farol is one decorator, zero infrastructure changes, and it tells you automatically when something goes wrong — cost spikes, quality drops, latency issues.
Would love honest feedback — is this solving a real problem for you? What would you add?
