WHOIS Lookup: registrar, dates & name servers via RDAP
Free in-browser WHOIS lookup. Uses the modern RDAP protocol (the JSON-based successor to WHOIS) via rdap.org. Returns the registrar, IANA ID, creation / expiry dates, name servers, DNSSEC, status (EPP) codes and abuse contact — for every TLD that publishes an RDAP endpoint.

It queries rdap.org, a public RDAP gateway. RDAP is the modern, JSON-based successor to WHOIS and is exposed by every TLD registry via CORS-friendly HTTPS endpoints.
Most TLDs now redact registrant contact details to comply with GDPR and ICANN privacy rules. You'll usually see only the registrar, dates, name servers and abuse contact email.
All gTLDs (.com / .net / .org / .io / .dev / .ai / etc.) and most ccTLDs that have an RDAP endpoint. A handful of older ccTLDs still only publish classic WHOIS (port 43) and won't return data here.
