Owl vs Arize for evaluating and improving user-facing agents
Owl captures the whole user journey across UI, chat, voice, API and MCP, scores the agent on what the user actually did next, runs candidate versions live against real production traffic, and opens the pull request that ships the fix. Owl never hosts or runs your agent.
Arize is a mature agent observability and evaluation platform with deep OpenTelemetry and OpenInference tracing, online and offline evals, automated failure discovery, and an open companion product in Phoenix.
The difference is the unit of analysis. Arize evaluates the agent and its output. Owl evaluates the journey the agent sits inside, including what the user did in the product before and after the conversation. Many teams run both.
