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.
Measure engineering work and AI's real contribution to it.
Brings AI metrics, DORA and SPACE-based benchmarks and developer feedback into one view so you can see where work stalls from prompt to production.
Relates AI-assisted usage to merges, quality and cost, with per-engineer AI usage and AI score reporting plus benchmarks against 1,000+ organisations.
Connects token and prompt spend to engineering output so you can see what you are getting for every AI dollar spent.
Weave Router classifies each prompt and routes it to the model with the best quality-per-token, learning from team feedback over time.
