Free Monitor Certificate expiry via RSS

The expiration of TLS certificates is usually monitored with established monitoring solutions. Sometimes monitoring happens via services that send e-mails when the expiration date comes closer. Often times, these services require a sign-up.

I created an entirely free service that monitors the expiry of TLS certificates via RSS without any sign-up.
