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.

The AI-powered interface for every database you run
Type a question in plain English and get an instant answer drawn from your connected data, without writing SQL by hand.
The AI editor reviews your SQL, corrects mistakes and suggests improvements, then turns result sets into presentation-ready charts automatically.
A snappy grid built from scratch for fast navigation of large tables, with customizable table plugins and edit-in-place controls.
Compose analytics boards manually or hand them to the AI, then embed charts anywhere using open-source web components.
