Check Domain

Search domain availability, WHOIS records and registrar prices in one pass

Multi-extension availability in one search

Enter a brand word or full domain and see how it fares across .com, .net, .org, .io, .ai and other extensions at the same time.

Registry-backed RDAP results

Availability is checked against each registry's RDAP service rather than inferred from DNS records, reducing misleading 'available' answers.

Public WHOIS and RDAP detail

For registered names, inspect registrar, registration and expiry dates, nameservers and the registry source behind the record.

Registration vs renewal price comparison

First-year offers sit next to renewal costs so you can judge the real long-term price of a name before buying.

Strengths & Pros

+Shows registration and renewal prices side by side, avoiding cheap-first-year traps
+Covers many extensions in a single search
