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.
One control plane for distributed performance testing and orchestration
Manage test execution, scheduling triggers, and environment configuration from a single console instead of coordinating scripts and machines by hand.
Scale load generation across a distributed set of runners while keeping test definitions and results in one place.
Run UI checks alongside load execution to see real user behaviour at the exact moment load peaks, not hours afterwards.
Observe performance signals during the run so issues can be diagnosed and fixed before the test finishes.
