Check Domain NEW

Check Domain performs domain availability checks, WHOIS and RDAP lookups, and registrar price comparisons across multiple top-level domains. It returns registry-backed availability status instead of relying on inferred DNS records, reducing false positives for .com, .net, .org, .io, .ai and other TLDs. Search results show WHOIS/RDAP records, registry source, nameservers, creation and expiration dates, and status codes. Users can compare registration and renewal prices side-by-side, inspect ownership and technical record details, and filter results by extension. Workflows supported include brand name validation, technical investigation, purchasing research, and portfolio management. Basic domain lookups run without creating an account, with optional tracking features for ongoing searches and audits.
