Comet's open-source platform for tracing, evaluating, and monitoring LLM applications.
Opik, from Comet, is an open-source platform covering the full loop: tracing LLM and agent runs, running evaluations, and monitoring in production, with a prompt playground alongside.
It is self-hostable, and brings Comet's experiment-tracking heritage to the LLM observability space.
Where it's ideally used
A fit when you want an open-source, self-hostable platform spanning tracing, evals, and production monitoring.
Where it doesn't fit
A younger project than the most established observability tools — weigh ecosystem depth before committing.
