Website & Domain Monitoring

Set it and forget it. We check your domain on a schedule and alert you the moment something breaks — the site goes down, a certificate or the domain itself is about to expire, or your DNS records change unexpectedly. No account needed.

Alerts when the site stops responding

What you can watch

  • Uptime — get told when your site stops responding, before your customers do.
  • SSL expiry — an expired certificate throws a scary browser warning; we warn you 14 days out.
  • Domain expiry — the most avoidable outage of all; we warn you 30 days out.
  • DNS change — catch unexpected record changes (a hijack, a misconfigured deploy) as they happen.

How alerts reach you

Add an email or a webhook (Slack, Discord, or your own endpoint). We only notify on a change — when something goes wrong and again when it recovers — so you’re never spammed.

Frequently asked questions

Do I need an account?

No — creating a monitor returns a private manage link. Bookmark it; it's how you view and delete the monitor.

How often does it check?

On a schedule via a cron job. You're only alerted when something changes (goes wrong) and again when it recovers, so you're never spammed.
