Best for

Athina AI

Pick Athina AI if you need a shared eval and observability layer that PMs, QA, and engineers can all work in without stitching together three separate tools.

Opik

Pick Opik if you're shipping LLM agents and want open-source tracing, evals, and guardrails you can self-host or run on Comet's free cloud.

Not for

Athina AI

Skip it if you want a fully open-source stack or need self-hosting without committing to an Enterprise contract.

Opik

Skip it if you only need lightweight prompt logging or you've already standardized on LangSmith/Langfuse and don't want a migration.

Cons

Athina AI
