Never get caught by a surprise expiry again
Know before your
certificates expire.
CertWatch monitors your SSL certificates and domain registrations and emails you weeks before either one expires — so an outage never starts with “the cert lapsed.”
🔒
SSL certificate expiry
We connect to each host daily, read the live certificate, and warn you at 30, 7 and 1 days before it expires.
🌐
Domain registration expiry
CertWatch also watches when the domain itself is up for renewal — the lapse that quietly takes whole sites offline.
✉️
Alerts that reach you
Email and Slack alerts the moment a certificate or domain crosses a threshold. No dashboards to babysit.
⚡
30-second setup
Add a domain, done. No agent to install, no DNS changes, no code. We do the checking from our side.
Simple pricing
Start free. Upgrade when you have more than one thing to watch.
