Agent observability, evaluation, and continuous improvement for production AI
Capture spans, traces, and sessions across agents and LLM calls using OpenInference conventions built on OpenTelemetry, so instrumentation stays portable.
Run evaluations at span, trace, and session level to grade retrieval quality, tool use, and final answers across large production datasets.
An in-product agent that inspects traces, diagnoses likely root causes, and proposes fixes that engineers can review before shipping.
Self-host the leading open-source tracing and eval tool when you need to keep trace data inside your own infrastructure.

Subscriptions replace advertising, so there are no sponsored results, affiliate links, or data sales influencing what you see.
Rank any website up or down, pin favorites, or block domains entirely so your results match your own standards.
Append a question mark to get an AI answer above the results, or chat with the Assistant for deeper tasks with sources included.
Restrict searches to categories like forums or news, or jump straight into a specific site's own search with shortcuts.
