Phoenix gives OpenTelemetry-based tracing, evaluation and experiment tracking for LLM applications, and runs entirely on your own infrastructure, which keeps traced prompts and outputs in your hands. Read the licence before adopting it: GitHub reports the repository as unlicensed, and the file is the Elastic License 2.0, which is source-available rather than open source and specifically restricts offering the software to others as a managed service. For internal use that restriction rarely bites, but it is not the same grant as the Apache and MIT projects alongside it.

How this tool was scored

Key handling 87/100 (where your key rests and who sees it, comparable across any licence) and verifiability 33/100 (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 9/20: A public repository exists but the project is not open source.
  • 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] Ships a container definition, so it can be self-hosted on your own infrastructure. 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.
