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.

AI anomaly detection for sensor and time-series data
Learns the normal behavior of each sensor or machine automatically, so teams do not have to hand-tune thresholds.
Accepts streaming sensor readings and historical series, scoring each new data point against the learned baseline.
Notifies the right people when behavior drifts away from normal, so incidents can be investigated early.
Supports loading data from CSV files and common monitoring sources for quick evaluation.
