Uptime monitoring
Watch everything that can break. Trust the board that says it didn't.
PageWarden checks your sites, SSL certificates, domains, content, ports, DNS and host reachability, confirms failures from multiple regions, and alerts you in email, Slack, Discord or a webhook. One tool, one status board, no noise.
Free plan, no credit card. 3-day trial on any paid plan.
The green you can believe.
In most dashboards green is decoration. In PageWarden it means the check actually ran and actually passed. Before a retryable failure is ever recorded, it is re-checked from multiple regions and a quorum decides, so a single bad network path will not wake you. A board that is green because it was verified, and red because it was confirmed.
All-in-one
Seven things that can break, watched in one place
Most teams stitch uptime, certificates and DNS together from three services. PageWarden is one.
Uptime
HTTP/HTTPS checks that classify each result up, degraded or down.
Checks as often as every 60 secondsSSL certificate
Track certificate expiry and validate the chain before a cert lapses.
Watches the full chain and the expiry dateDomain expiry
WHOIS-based tracking of domain registration expiry. Catch a forgotten renewal.
Tracks the registration expiry dateKeyword / content
Assert a page contains, or does not contain, specific text.
Alerts when expected text goes missing, or bad text appearsTCP port
Monitor a raw TCP service on a specific port. Up or down on connectivity.
Mail, database, game servers, anything on a portDNS record
Verify records resolve as expected, with an optional expected value.
Watches A, AAAA, CNAME, MX, TXT and NS recordsPing (ICMP)
Raw host reachability over ICMP, separates a host being down from a service being down, with no port or HTTP. Loss-aware.
Tells a down host apart from a down serviceIncidents you can trust
One incident per outage, not a flood of pings
Two consecutive failed checks open an incident, dated at the first failure. Two consecutive successes resolve it at the recovery time. You get one clean timeline per outage with the failing target, the latest error, and the in-window check results.
A transient or blocked failure is retried once before it is recorded, so a momentary blip never opens a false incident. Calm by construction.
Multi-region confirmation
Confirmed from several vantages before you are alerted
PageWarden probes from New York, San Francisco, Frankfurt, Singapore and Sydney, plus the primary vantage. A single bad network path or a datacenter-IP block will not page you. A real outage, confirmed across regions, will.
Starter and Pro add continuous per-region scanning, per-region uptime history, a response chart and the live region map.
Downtime alerts
Alerts where you already are
PageWarden notifies you on incident open and recovery, with no duplicate sends and a retry ladder. Every channel has a send-test button.

A plain-English read on what likely broke
When an incident opens, PageWarden adds a short hypothesis about the likely cause to the incident and the alert. It is a quiet assist, clearly marked verify before acting, not a headline. Available on Starter and Pro.
