Check from 18 global PoPs at once. Tell a real outage from one bad region with consensus-based status.
p50 / p95 / p99 with full DNS → TCP → TLS → TTFB waterfalls. Catch the slow tail early.
Per-monitor latency baselining flags regressions static thresholds miss — no tuning required.
Flap detection, maintenance windows and dedup feed PagerDuty, Slack & webhooks. Wake the right person, once.
Track certificate chains and domain registration. Warned 30 / 14 / 7 days before anything expires.
Define SLOs and watch error budgets burn in real time. Monthly availability reports stakeholders can read.
Composable panels, time-range zoom and live auto-refresh — the console your team already knows.
Everything is an API. Provision monitors as code, stream results to your warehouse, embed status anywhere.
Point us at a URL, host:port, or domain. Pick check type (HTTP, TCP, ICMP, DNS, SSL), interval, and regions.
Distributed workers run your check from every selected region on schedule, recording latency, status, and full request waterfalls.
Consensus + flap detection decide real incidents. Dashboards update live; the right on-call engineer is paged in seconds.
