What does PageWarden monitor?

Six things that can break: website uptime (HTTP/HTTPS), SSL certificate expiry and chain validity, domain registration expiry, page content and keywords, TCP ports, and DNS records. One tool covers what most people stitch together from three.

Check intervals are plan-based, down to 60 seconds on Starter and Pro. Free runs every 30 minutes and Hobby every 5 minutes.

Do I need a credit card to start?

No. The Free plan needs no credit card. New accounts also get a 3-day Pro trial with full Pro features.

What channels can PageWarden alert?

Email on every plan, plus Webhook, Discord and Slack on paid plans. Every channel has a send-test button so you can confirm delivery before you rely on it.

What is multi-region confirmation?

Before PageWarden records a retryable down, it re-checks from multiple regions and a quorum decides. A single bad network path will not wake you. A real outage, confirmed across regions, will. Continuous per-region scanning and history are on Starter and Pro.

Can I monitor SSL and domain expiry?

Yes. SSL certificate monitoring tracks expiry and validates the chain, and domain expiry monitoring uses WHOIS to catch a forgotten renewal. Both are available on every plan.

Is there a free plan?

Yes. The Free plan covers one monitor with uptime, SSL and domain checks and email alerts, with 14 days of history. No credit card required.

UPTIME MONITORING

Watch everything that can break. Trust the board that says it didn't.

PageWarden checks your sites, SSL certificates, domains, content, ports and DNS, confirms failures from multiple regions, and alerts you in email, Slack, Discord or a webhook. One tool, one status board, no noise.

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

Six 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.

60s checks

SSL certificate

Track certificate expiry and validate the chain before a cert lapses.

chain + expiry

Domain expiry

WHOIS-based tracking of domain registration expiry. Catch a forgotten renewal.

INCIDENTS 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.

Root-cause hypothesis

Origin is returning 503 across regions while the edge stays reachable, which points to an overloaded or failed backend rather than DNS or TLS. Check the app servers and recent deploys. Verify before acting.

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.
