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.

Every reported issue comes with a reproducible proof of concept, request and response detail and a blast-radius assessment.
Thousands of short-lived agents each pursue one focused attack objective under a persistent coordinator.
A steerable headless browser plus Burp, ZAP, Nuclei, sqlmap, Semgrep and custom payloads.
Trigger from CI on every merge, or run continuously against staging and production to keep pace with releases.
