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.
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.
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.
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.
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 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.
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.
Type the name, pick a warning window, done. Every feature is on the free plan.
