About

Opik records agent runs as full trace trees across multi-step agents and tool calls. It runs LLM-as-a-judge metrics over datasets and experiments, and a PyTest integration can run LLM pipeline tests on every commit. Production dashboards and online evaluation rules cover monitoring. The platform is Apache-2.0 licensed and free to self-host.

Use cases: monitoring-observability, llm-evaluation
