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.
An AI QA agent that tests your website the way a real customer would
The agent discovers and then replays your booking, contact, signup or checkout journey in a real browser every week — stopping before any real transaction or account is created — and records the entire session.
Loads up to 15 of your key pages every day on desktop and mobile, checks every internal link, and re-confirms broken links in a browser before reporting them.
Catches JavaScript errors that only surface in production, plus phone-sized layout and menu problems such as overflowing elements or a broken mobile menu.
Site-wide monitoring for expiring SSL certificates, domain renewal dates and search-visibility issues that could take a whole site offline or hide it from search engines.
