Domain Intelligence: WHOIS/RDAP, DNS, SPF/DMARC & SSL

Check thousands of domains at once: available or registered, plus registrar, creation and expiry dates, days until expiry, and nameservers. Check a name across many TLDs, or find domains expiring soon. Uses official RDAP, the modern WHOIS. Free.

Full domain security audit in one call: SSL/TLS, DNS, SPF/DKIM/DMARC, security headers, WHOIS, blacklist, tech stack — PLUS subdomain-takeover risk and public S3-bucket exposure detection, which no other domain-audit tool checks. Returns a 0-100 health score + fix list. No API key, no login.
