Domain monitoring that warns you
before something breaks.

Registration data and expiry through RDAP, DNS records and DNSSEC, TLS certificates and their chain, whether the site responds, and mail authentication — MX, SPF and DMARC. Every result is stored as a snapshot and compared against the previous one, so an alert can tell you what changed rather than only that something is wrong.

At the next scheduled check, which runs every 6 to 24 hours depending on your plan. Domzor is not a real-time uptime monitor and does not claim to be: it watches the things that break on a scale of days and weeks — a certificate lapsing, a nameserver quietly changing, a renewal date approaching — where hours of latency cost you nothing and a missed deadline costs you a domain.

Coverage follows what each registry publishes. Most TLDs answer over RDAP, which Domzor reads directly. For .se and .nu there is a WHOIS fallback, since those registries publish more that way. Where a registry gives nothing useful, Domzor says so on the domain rather than showing a confident date it had to guess at.

No, and it never will. Domzor is not a registrar and holds no authority over your domains — it watches them and tells you what needs doing. Renewal, transfers and payment stay with whoever you registered through. That separation is the point: a monitor that could also act on your domains would be a much larger thing to trust.

Paste a list or upload a CSV and Domzor starts fetching registration data immediately. There is no per-domain form to fill in. You can tag domains, assign an owner or client, add notes and set priority, then filter and export the result whenever you need to report on it.

On servers in Finland, operated by Hetzner in Germany. Verification and alert email goes through Brevo in France. All of that is inside the EEA. One exception is disclosed in the privacy policy: DNS diagnostics run through Google Public DNS in the United States, which receives the domain name being checked and nothing else — the query comes from our servers, not from your browser, so it carries no account details and no IP address of yours.

Sign-up needs an invitation code at the moment. Leave your address below and we will send you one as seats free up. We onboard a few at a time on purpose — a beta where the developer can still answer every message is worth more than a big one where nobody does.

It stays. Five domains, daily checks and 30 days of history, permanently and without a card. Beta testers get plenty of notice before anything starts costing money, and nothing you have added disappears if you decide not to pay.
