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.
