Quick answer

What does a domain expiry checker do?

A domain expiry checker looks up a domain's registration record via RDAP and reports its expiry date, registrar, status codes and nameservers. Pinglyra shows the days remaining until expiry alongside SSL, DNS, uptime and more, and once a domain is monitored it can alert you 90, 30 and 7 days before the registration lapses.

Domains expire silently and take the whole site and email offline when they do. This free checker reads the domain's RDAP record so you can see exactly when it expires and renew in time.

Why domain expiry matters

An expired domain takes the website AND email offline instantly, and can be snapped up by someone else. For agencies managing many client domains, a single missed renewal is a crisis.

  • Expiry takes the site and email down at once
  • Lapsed domains can be hijacked
  • Renewal dates are easy to lose track of across many clients

What this checker reports

  • Domain expiry date and days remaining
  • Registrar and domain status codes
  • Nameservers from the RDAP record
  • Graceful handling for TLDs without RDAP

Part of a full website health scan

This tool runs Pinglyra's full free scan, so alongside this check you also see uptime, SSL, DNS, email security, security headers, SEO, performance, links and accessibility - combined into a single 0-100 Website Health Score that shows what to fix first.

Passive and read-only

Every check is passive: Pinglyra only reads what your site already exposes publicly. There is no intrusive scanning, no form submission and no impact on the live site.

  • Continuous monitoring across all client sites

  • Included in white-label monthly reports

Frequently asked questions

Is this domain checker free?
Yes - check any domain with no account. A free Pinglyra account adds continuous expiry monitoring with 90/30/7-day alerts.
What is RDAP?
RDAP is the modern, structured replacement for WHOIS. It returns reliable, machine-readable registration data, which is why Pinglyra uses it instead of parsing inconsistent WHOIS text.
Does it work for every domain?
Most common TLDs publish RDAP. A few do not - for those the checker reports gracefully rather than guessing.
Can Pinglyra alert me before a domain expires?
Yes. With a domain monitored, you get alerts at 90, 30 and 7 days before expiry, plus it appears in your client reports.
