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.
No credit card · no agent to install

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.
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 the monitor's page shows the days left, the expiry date and the registrar — 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), once a day. Nothing to install, nothing to expose. Set how many days' warning you want and forget about it.
It's a public lookup, so it runs from CuliPulse — unlike internal checks, you don't need to run anything.
Registration changes about once a year, so a daily check is plenty — and gentle on the registries.
Pick your threshold (say 30 days). You're alerted in time to renew — and a standalone domain monitor alerts 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 show as inconclusive rather than a false expiry alert.
Alerts you can trust
A heads-up, not a 3am page.
Domain expiry is a renewal reminder, not an outage.
Purely advisory: it never flips your status light.
The domain is the whole job, so the monitor goes red when the registration lapses.
