What is Opik?

Opik records every LLM call and agent step as a trace tree, so you can see what a multi-step agent did and why. On top of the traces it runs evaluations with datasets, experiments and LLM-as-a-judge metrics for hallucination, moderation and RAG quality, and it manages prompts. Production dashboards, online evaluation rules and guardrails cover live traffic, a PyTest integration checks pipelines in CI, and an Agent Optimizer SDK tunes prompts. Many frameworks are supported natively, including Google ADK, Autogen and Flowise.

Good fit if

  • You ship LLM features and need to debug traces and measure quality before and after release.
  • You want evaluation and monitoring on your own infrastructure instead of a hosted LLMOps service.

Look elsewhere if

  • You want a lighter tracing and prompt tool with a simpler deployment: Langfuse.
  • You need classic error and performance monitoring for application code: Sentry.

Before you adopt it

Opik is Apache-2.0, and the README says the full platform is free to self-host; no paid parts were found in the repository. Comet requires a CLA from contributors. The self-hosted stack is large, with MySQL, Redis, ClickHouse, Kafka and MinIO among sixteen Compose services, and a Helm chart is provided for Kubernetes.
