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.
Uptime monitoring, on-call and status pages in one calm tool
Web and HTTPS endpoint checks with status code, keyword, response time and certificate validation, plus ping, TCP port, DNS record and mail server monitors — checked every 30 seconds from four regions.
Branching escalation paths decide who is notified, where and when, so severe alerts page someone immediately while warnings can wait for working hours.
Page the on-call engineer by SMS or phone call with one-key acknowledgement, and run the whole incident from Slack with /incident declare.
Publish branded status pages that follow every incident update, available in six languages and matched to the visitor.
