Domain expiry monitoring

Never get blindsided by an expired domain.

An expired domain takes everything down — site, email, the lot — and the renewal notice always lands in the wrong inbox. CuliPulse watches your domain's registration and warns you in good time. No agent, no setup beyond the name itself.

Two ways to use it

Watch a domain on its own, or alongside your site.

A standalone domain monitor

Watch a domain you don't (or don't yet) serve a website on — a parked domain, an email-only domain, a brand you're holding. Its status reflects the registration: healthy → expiring soon → expired.

no website needed

An add-on to any HTTP monitor

Already monitoring a site? Tick one box to also watch its domain. You get a heads-up and a “domain: 27d” badge — your site's up/down status is never affected by a future renewal date.

How it works

Agentless, and refreshingly boring.

CuliPulse reads your domain's registration straight from the registry (over RDAP, the modern replacement for WHOIS) — from our edge, once a day. Nothing to install, nothing to expose. Set how many days' warning you want and forget about it.

No agent

It's a public lookup, so it runs from CuliPulse — unlike internal checks, you don't need to run anything.

Checked daily

Registration changes about once a year, so a daily check is plenty — and gentle on the registries.

Warn N days before

Pick your threshold (say 30 days). You're alerted in time to renew, and again if it ever actually expires.

Shows the exact days remaining, the expiry date, and the registrar. Works for all common domains; a few country domains without a public registry feed will say so plainly rather than guess.

Alerts you can trust

A heads-up, not a 3am page.

Domain expiry is a renewal reminder, not an outage — so on a website monitor it's purely advisory and never flips your status light. A standalone domain monitor, whose whole job is the domain, does go red when it lapses.
