What is Polarity?
Sandboxed eval infrastructure that makes AI agents reliable in production.
Polarity is sandboxed eval infrastructure for AI agents. It monitors every agent decision in production, surfaces failure patterns before users hit them, and turns trajectories into evals that compound agent reliability over time. Each task runs inside an isolated Docker sandbox preloaded with real backing services (Postgres, Redis, S3, internal APIs).
