Hey Product Hunt 👋
We’ve been building Handit for the last 9 months — it started as a tool to help us debug AI agents in production… and quickly became much more.
Handit is the open-source engine for self-improving AI agents.
It evaluates every decision your agent makes, generates better prompts or model calls, A/B tests the fix, and helps you ship what actually works — automatically.
We built it because AI agents are powerful, but they break in real life.
They hallucinate, drift, and degrade silently — Unlike observability tools that just flag issues, Handit actually fixes them and shows you the full impact.
It’s:
✅ Open source
✅ Fully traceable (every input/output, decision, tool call)
✅ Stack-agnostic (LangChain, RAGs, custom pipelines — it works anywhere)
We’re already seeing teams use it to:
- Catch hallucinations before users complain
- Auto-tune prompts using real evaluations aligned to their business KPIs
- Monitor + improve agent workflows without extra infra nor extra time from their engineering teams.
We’d love to know:
How are you managing your agents in production today?
What would you want to auto-optimize or evaluate better?
💬 Drop any questions, ideas, or feedback below — we’re reading everything.
🙏 And if Handit resonates, we’d love your support!
Thanks for being here. Excited to keep building with you.
— Jose & the Handit team
