Know your site is down
before your customers do.
SitePulse Lab runs continuous availability and performance checks from distributed probes, then tells you the moment something drifts — with the request trace attached, not just a red dot.
See how it works Live statusUptime probes
HTTP, TCP and DNS checks on a 30-second interval, executed from independent regions so a single bad route never pages you at 3am.
Response budgets
Set a latency budget per endpoint. We alert on sustained drift, not on one slow request, so the signal stays worth reading.
Core Web Vitals
LCP, CLS and INP sampled on real page loads and tracked over time, with regressions tied back to the deploy that caused them.
Certificate watch
Expiry, chain integrity and protocol downgrades — flagged well before a browser starts refusing the handshake.
Traceable alerts
Every alert carries the failing request, status line and timing breakdown, so triage starts with evidence instead of a guess.
Quiet by default
Flap damping and maintenance windows are on from day one. An alerting tool that cries wolf gets muted, and a muted tool is useless.
