Domain Expiry Checker

RDAP (Registration Data Access Protocol) is the IETF-standard successor to WHOIS. Where WHOIS returns free-form text that varies by registry, RDAP returns structured JSON, so dates, registrar and status are reliable to parse. This tool finds the authoritative RDAP service for the domain's TLD from the IANA bootstrap and queries it directly.

Not every registry runs an RDAP service yet — many ccTLDs in particular don't publish one, so there is nothing to query. The lookup runs on Uptimeify's EU servers; the domain you enter is used only for the query and is not stored. As an EU-built, EU-hosted provider, we keep this off US infrastructure and clear of US Cloud Act exposure.

A lapsed domain is one of the most expensive outages there is — and easy to forget across a portfolio of client domains. Check expiry here, then let Uptimeify monitor your domains' expiry and DNS continuously and alert you well before one lapses, so a renewal never slips through.
