Zonekeeper

Zonekeeper checks every domain you own once a day: nameservers, mail records, certificates and registration dates, across whichever registrar, DNS host and hosting panel each one uses. It maps each record to what it actually serves, so when something changes it can tell you in plain English what breaks, how to fix it, and by when a provider will act. Below is a sample account with four domains; pick one, then simulate a nameserver change to see the alert it would send.

Example data: the domains, providers and dates are invented. Nothing here checks a real domain.

What to try

• Select fernhollow.example and press "Simulate nameserver change": the zone moves to a parking host, and the map shows the site, the mail and the agent subdomain going dark, with the provider's deletion deadline.
• Select lanternworks.example to see a softer alert: a DMARC record that is missing and a certificate that expires in 9 days.
• Undo the simulation and compare: the healthy view is what a quiet daily digest looks like.
