Enter a domain and see exactly when it expires, who the registrar is, and whether renewal is locked - straight from the registry's live RDAP data, not a stale WHOIS mirror. No signup.
Expired domains have taken down household-name services - the renewal email went to a departed employee's inbox, the card on file expired, the domain lived in an account nobody remembered. When a domain lapses, everything on it goes: website, API, and - the part that turns bad into catastrophic - email, including the inbox that password resets and registrar warnings go to. Recovery from redemption periods is slow and expensive; recovery from a snapped-up domain sometimes never happens.
The registry status list is worth a glance: clientTransferProhibited is normal (it's transfer-lock, protecting the domain), autoRenewPeriod or renewPeriod means renewal just happened or is in grace, and anything with redemptionPeriod or pendingDelete means the domain is already past expiry and in the danger zone. A registrar shown alongside a healthy day count and a transfer lock is the picture you want.
Some country registries don't publish expiry dates over RDAP (or publish limited data). If the checker reports no expiry for a ccTLD, that's the registry's policy rather than a lapsed domain - your registrar dashboard remains the source of truth for those.
