## Best for
Teams that want a fully self-hostable alternative to commercial LLM observability tools.

## About Opik
Opik, built by Comet, covers the LLM application lifecycle from the first trace in development to production monitoring: agent tracing and observability, LLM-as-a-judge and other evaluations, prompt management and production dashboards. It is Apache-2.0 licensed and free to self-host in full, with a hosted option on Comet.com and an MCP integration for coding agents.

## Install
