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.

Automate work across thousands of apps — no code required
Connect thousands of apps with a visual editor, using both point-and-click logic and natural language to define each step.
Connect AI tools such as Claude, ChatGPT and Cursor to your apps so they can read data and take real action.
Create AI assistants that answer questions and complete multi-step tasks across your connected systems.
Store structured data your workflows can read and update, keeping records in sync across tools.
