How does domain expiration monitoring work?

Moonitor queries RDAP — the structured successor to WHOIS — for your domain's registration data and tracks the expiry date, alerting you as it approaches.

Why monitor expiry if my registrar sends reminder emails?

Registrar reminders go to one inbox, often an old one, and stop mattering the day the card on file expires. Moonitor alerts your whole team on the channels you already use for incidents.

Which domains should I monitor?

Every name that would hurt to lose: the product domain, marketing domains, redirect and typo domains, and any domain your email runs on.

Does it work for all TLDs?

Moonitor uses RDAP, which is supported by all gTLDs and most ccTLDs — coverage is broad and growing as registries complete the WHOIS transition.

Part of every Moonitor plan

Domain expiration monitoring, because renewals get forgotten

Losing a domain is the rare outage that can be permanent. The credit card on the registrar account expired, the renewal email went to a mailbox nobody reads, and days later the website, the API and every company email address stop working at once — with a real chance someone else registers the name.

Moonitor tracks your domains' registration expiry over RDAP (the modern replacement for WHOIS) and alerts you well ahead of the date, on channels people actually read.

How it works

Add your domains
Point a domain monitor at each name you own — the main product domain, the marketing domains, the typo-catchers.
We query RDAP
Registration expiry is checked against registry data directly, not scraped WHOIS text, so dates are reliable across TLDs.
Warned well ahead
Domains approaching expiry surface on your dashboard's expiring-soon view and open alerts before the deadline.
Renew on your terms
The alert arrives while renewal is still routine — no grace-period fees, no auction sniping, no weekend emergency.

What you get

RDAP-based accuracy

Structured registry data instead of fragile WHOIS parsing, for dependable expiry dates across TLDs.

Expiring-soon dashboard

Domains and certificates within 30 days of expiry are surfaced together, so nothing sneaks up.

Alerts people read

Email, Slack, Discord, Telegram and webhooks — renewal warnings land where your team already looks.

Pairs with SSL monitoring

Watch the certificate and the registration side by side; either one expiring takes you down.

Incident history

Expiry warnings and recoveries are recorded like any other incident, with timestamps.

API-manageable

Add every domain you register through the API, so monitoring is part of buying the name.

Every failure verified before you’re alerted

Moonitor re-runs every failing check from a second country before opening an incident — so a network wobble near one checker never becomes a false alarm on your phone. Explore the full feature set, read the docs, or automate it all with the API.
