Site Monitors

For agencies and freelancers

Never let a client's SSL certificate or domain expire again.

Certificates are getting shorter-lived, and renewals fail quietly. Get alerted before a client's site shows a security warning, with uptime monitoring for every site in one dashboard.

Why this keeps happening

Certificate lifetimes are shrinking in stages, to 47 days by 2029. That means far more renewals per year across every site you manage, and far more chances for one to be missed.

Certificate expiry alerts

Emails 30, 14, 7, 3 and 1 days before a certificate expires, plus alerts for hostname mismatches, broken chains and self-signed certificates.

Domain expiry alerts

Emails 60, 30, 14, 7 and 1 days before a domain's registration runs out, so a forgotten renewal never takes a site offline.

Uptime checks

Every site is checked every 5 minutes. We double-check before emailing you, so a single hiccup doesn't wake anyone, and we email again when it's back.

One dashboard

See every site's uptime, certificate and domain status in one place, and add, edit or remove sites whenever you like.
