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.
Turn policies into AI-enforced workflows you can prove
Centralise policies and SOPs with version control and governance mapped to frameworks such as ISO 9001, SOC 2, SOX and FDA requirements.
Turn policies into structured workflows with owners, due dates, conditional logic and approvals, so every step is followed rather than assumed.
Monitors regulatory changes, automates the associated work and flags risks and gaps before they turn into audit findings.
Records who completed each step and when, with required file uploads, form entries and approvals attached to the task.
