Uptime & SSL Certificate Checker

Enter a domain to see whether it responds, how fast, and how many days remain on its SSL certificate. A quick way to catch an expiring certificate before your visitors do.

Public sites only. We fetch the page once (no redirects followed) and read the certificate on port 443. Rate limited to keep things friendly.

Why this matters

Expired certificates throw scary browser warnings and drive visitors away. Most outages of this kind are entirely preventable.
Renew early. If a certificate has under ~15 days left and isn't auto-renewing, treat it as urgent.
Automate it. Certificates should renew themselves and alert you well before expiry.

We set up monitoring and auto-renewal so this is never a surprise. Get in touch or see our other free tools.
