My Domains

Add your domains and see at a glance how many days are left until the domain registration and TLS certificate expire.

Your domain list is remembered only in this browser (localStorage), so it's there straight away when you come back — no accounts, nothing stored on the server. The same list is also encoded in this page's address after the # sign — copy it to move the list to another device. To check the dates, each domain is sent to the same tools used by WHOIS and SSL/TLS Checker. Details: Privacy Policy.

What the colours mean

  • ● Green — domain registration valid for more than 30 days, certificate for more than 14 days.
  • ● Yellow — domain: 8–30 days, certificate: 8–14 days. Time to plan a renewal.
  • ● Red — 7 days or fewer, or already expired. Action needed.
  • ● Grey — no data (check failed or no date in the response).

The certificate threshold is lower because Let's Encrypt certificates only auto-renew about 30 days before they expire.
