Polarity monitors every agent decision in production, surfaces failure patterns before users hit them, and turns trajectories into evals that compound your agent’s reliability over time!
Hey Product Hunt 👋
Alex here, founder of Polarity.
Most agent teams I've talked to have a 95% pass rate on their eval suite and a 60% pass rate in production. The gap is where products die, and most teams find out from a customer ticket hours later.
Polarity closes that loop gap with ease:
→ craft agent behaviors in the dashboard
→ learns from agent behaviour and finds new opportunities for tracking
→ Slack alerts the second your agent misbehaves.
Wrong tool call, skipped guardrail, latency going past thresholds; it’ll all show up in your team's slack channel with the trace.
Three SDKs currently supported:
→ Go
→ Python
→ TypeScript
Leave any feedback in the comments, thank you product hunt!
- Alex ❤️
