Monitoring · Free for 10 monitors
SSL certificate monitoring
Renew every certificate before visitors see a browser warning. Checkmeup reads the certificate once a day and warns you three times before it expires.

- Alerts when
- It expires in 30, 14 or 7 days, or is already invalid
How it works
Enter a hostname, or paste a URL and Checkmeup keeps the hostname. Once a day it connects on port 443 over TLS, the way a browser does, and records the certificate's issuer, expiry date and days left.
You get one alert as the certificate crosses 30, 14 and 7 days left, never two for the same threshold, and an alert at once when it has expired or doesn't validate.
Alerts
Down and recovery alerts go to email, Telegram, Slack or a signed webhook on every plan, and by SMS on paid plans. A monitor with nowhere else to alert emails everyone in your account, so an alert is never lost.
What it doesn't tell you
The check verifies the certificate the way most clients do, from one place. It doesn't test every client's trust store, and a host that serves different certificates by region may show you only one of them.
