How it works
Three steps from an empty dashboard to checks that run on their own.

Choose how many days of advance notice you want.
Renew before it expires
Get alerted well before your certificate lapses.
Frequently asked questions
The questions people ask most before they start monitoring.
Does Uptime read my certificate automatically?
No — enter the expiry date and issuer manually; Uptime checks it against today's date daily.
Will I get alerted more than once?
Yes, at each configured threshold, subject to your alert cooldown.
