Overview

Open-source LLM tracing + evaluation. OpenInference standard for traces; runs locally with one pip install. The OSS-first pick for teams that want LangSmith-shaped functionality without vendor lock-in.

Stack & relationships

How Phoenix (Arize AI) relates to other entries in the catalog — recommended pairings, alternatives, dependencies, and edges to avoid. Each edge carries a one-line operator note from our editorial team.

Phoenix (Arize AI) ↔ ecosystem

Recommended stack

  • Pairs with
    OpenHands

    Phoenix instruments OpenHands tool-calls + LLM spans via OpenInference. Drop-in for trace + eval workflows.

  • Pairs with
    vLLM

    vLLM exposes OpenInference-compatible spans; Phoenix consumes them directly. The default OSS observability pairing for self-hosted vLLM deployments.

Alternatives

  • Alternative to
    LangSmith

    Phoenix is OSS (Apache 2.0) with OpenInference traces; LangSmith is closed-source with deeper LangChain integration. Pick Phoenix for vendor-independence.

  • Alternative to
    LangSmith

    LangSmith for the LangChain-native path; Phoenix for the OSS/OpenInference path. Pick by ecosystem fit and self-hosting requirement.

Pros

  • OSS, Apache 2.0
  • OpenInference standard for traces
  • Strong span visualization

Cons

  • Eval coverage trails LangSmith
  • Cloud dashboard requires Arize account
