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.
Free real-time analytics for open source projects on GitHub
Explore over ten billion GitHub events covering stars, commits, pull requests, issues and reviews, updated as new public events arrive.
Follow star-based rankings for hot repositories and browse editorial collections that map trends across languages, topics and technical fields.
Query the underlying event tables directly with SQL, or pull the same numbers into your own tooling through the public API.
Dedicated views track AI agent frameworks, LLM tooling and MCP servers, making it easy to compare a crowded and fast-changing space.
