Stop getting surprised by expired certificates.
certy monitors your SSL certificates and domains, and warns you in time.
See how it works →Set it up once. Stop worrying.
Three steps to never tracking a renewal date in a spreadsheet again.
01Add what to watch
Drop in the hosts and domains you care about — up to ten. Each list is private to your account.
02See it at a glance
A colour-coded dashboard shows days-left for every target: green when healthy, amber as it nears, red when it's urgent.
03Get warned in time
A daily check runs on its own and emails you at 30, 14, 7 and 1 days out — once each, never nagging.
Real certificate checks
A direct TLS handshake reads each host's certificate and its true expiry — the same thing a browser sees. Nothing to install on your side; we check every host from the outside.
Domain expiry too
A raw WHOIS lookup tracks when each domain registration lapses, so a missed renewal can't quietly drop your name from under you.
Tiered alerts, no spam
Warnings fire at 30, 14, 7 and 1 days out — each sent exactly once per expiry. Renew, and the countdown quietly resets.
Check on demand
Don't want to wait for the nightly run? Hit Check now on any target and watch the status refresh live.
It's just a handshake and a lookup.
No magic, no black box — the same low-level checks you'd run by hand, watched for you around the clock.
Start watching your certificates in two minutes.
