My domains
A watchlist for the certificates you are responsible for. Add a few domains, re-check them whenever you think of it — once a week is plenty — and see at a glance which grade slipped and which certificate expires next.
How this page works
No account, no server copy
The list lives in this browser's localStorage. Clearing site data removes it; another browser or device starts empty. Export the JSON to move it.
Checks are the same scan
Re-check calls the public JSON endpoint behind Domain Signature Health. Results are cached for an hour, and the endpoint accepts 10 checks per minute — so a full run walks the list one domain at a time.
Want to be told instead?
This page only knows what you refresh. For expiry warnings that arrive on their own, open a domain's report and subscribe to email alerts there.
The domain names on this list are never uploaded. When you press Re-check or Check all, that one domain name is sent to ecdsa.com so our server can connect to its port 443 — exactly what happens when you use the report page by hand. Nothing else is collected.
