Who Is Domain Checker

A domain checker that answers the three questions that actually matter. Is the domain available, who owns it, and when does it expire? Who Is Domain Checker is a quiet WHOIS tool for the moments those questions come up — naming a new project, debugging a misbehaving site, watching a brand domain you eventually want to grab, or auditing the records on something you already own. No account, no upsell, no popup over the result you came for. Type any domain and the app returns availability across more than 1,500 TLDs, the registrar holding the lease, creation, updated and expiry dates, current status and name servers. A DNS lookup view shows A, AAAA, MX, NS and TXT records, an SSL panel reads back the certificate chain and expiry, and every search is saved to a private domain history you can revisit later. Favourite the domains you care about and the app keeps a quiet eye on them, with a Home Screen widget that surfaces the next domain expiry coming up. Results cache for offline reading, so the domain availability and WHOIS records you pulled at your desk are still readable on a plane. The app stays out of the way otherwise — no accounts, no tracking, lookups that do not identify you, and the interface ships in 39 languages with full VoiceOver support. Built for domain hunters and investors, developers debugging DNS, marketers checking brand domains, security researchers and small business owners who just want a calm domain lookup that gives them the facts and steps aside.
