Website Monitoring
Free, registration-free uptime, certificate, and DNS-change monitoring for one domain at a time — no account, no password, just an email address.
What's monitored
- HTTP uptime — checked every 15 minutes against
https://yourdomain. Alerts when it stops responding (confirmed by two checks in a row), and again when it recovers, with how long the outage ran. - TLS certificate expiry — checked once daily. Alerts 30 days out by default (14 for a certificate valid 90 days or less, since those renew automatically), then again at 21, 7, 1 and 0 days.
- DNS change detection — checked once daily. Alerts when your domain's A records change from the last recorded snapshot. Off by default; switch it on when you want it.
- DMARC report collection — collects the aggregate reports mailbox providers already send about your domain. Off by default; needs a DNS record you add.
You'll get an email only when a check's status changes — not on every check, and not more than once every 6 hours for the same issue. Every check can be paused, or set to record without emailing, from your dashboard. Up to 5 domains per email address in this first version.
Not included yet: custom check intervals, a public status page, and SMS/webhook alerts.
