Polarity
Sandboxed eval infrastructure that catches agent failures before your users do.
Polarity is a sandboxed eval infrastructure for AI agents, providing isolated Docker environments with real backing services like Postgres and Redis. It scores agent behavior against invariants, detects non-determinism, and reproduces failures locally, ensuring accuracy for complex, multi-step agents.

How to use Polarity?
Use Polarity to test AI agents in production-like sandboxes before deployment. Define behavioral invariants, run evals, and get seed reproducers for failures. It catches issues like slow tool responses, hallucinated SKUs, or missed escalations, helping teams debug and optimize agent decision-making at scale.
