Opik traces, evaluates and monitors LLM applications, with datasets, LLM-as-a-judge metrics and a production dashboard. It matters here because tracing means recording prompts and outputs: run it self-hosted and those stay in your deployment, run the vendor's cloud and they do not. Judge models use credentials you supply. Apache-2.0, from Comet, which also sells the hosted version.

How this tool was scored

Key handling 87/100 (where your key rests and who sees it, comparable across any licence) and verifiability 70/100 (how much of that BYOAIK could confirm, lower for closed source). Neither contains a popularity signal.

  • Key Safety 21/25: The key lives in a deployment you run yourself.
  • Request Routing 17/20: Requests go straight from you to the AI provider.
  • Transparency 20/20: Source is public under Apache-2.0, so anyone can check how the key is handled.
  • Privacy 14/15: Local-first: it works without sending your data anywhere. Can be self-hosted, so the data path stays inside infrastructure you control.
  • Maintenance 10/10: Actively developed, with commits within the last three months.
  • Verification Confidence 1/10: Compiled from public documentation by an AI-assisted pass, not independently confirmed.

What was checked

Verification tier RESEARCH_ASSISTED, derived from the evidence below and not set by hand.

  • [REPORTED · RESEARCH] This listing was compiled by an AI-assisted research pass over the tool's public website, README and documentation. No person independently confirmed it.
  • [STRONG · SOURCE_SCAN] Supports a local model backend, so it can run with no cloud provider key at all. source
  • [CONFIRMED · SOURCE_SCAN] Most recent commit 2026-09-29, about 0 month(s) ago. source

How your API key is handled

You self-host the app, so your API key lives in your own deployment. Requests are sent directly to the AI provider. Because it can be self-hosted, your key never has to touch a third-party backend.

Setup

Deploy it (Docker/compose), add your provider API key in the admin or environment config, then select models.
