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.
GitHub-native analytics for developer experience and team performance
Measure commit, pull request, review and issue activity alongside how carefully contributions are reviewed and merged.
Generate retrospective talking points and recommendations from real engineering activity in a couple of clicks.
Surface slowdowns in the delivery pipeline before they become recurring schedule problems.
XP, levels, challenges, achievements and leaderboards turn process improvement into something teams can rally around.
