DomainIntel – WHOIS, DNS & Domain Checker

About

DomainIntel is the all-in-one domain research toolbar for web developers, SEO professionals, domain investors, and security researchers. One click on any website gives you everything you need to know about a domain.

WHOIS and registration - registrar, creation date, domain age, expiry, status codes, nameservers and DNSSEC, pulled live from authoritative RDAP registries.

DNS records - A, AAAA, CNAME, MX, NS, TXT and SOA via secure DNS-over-HTTPS.

Domain availability - instantly see whether a domain is registered or available; bulk-check up to 100 domains and export to CSV.

SSL certificates - issuer, validity window, days-to-expiry and certificate history from public Certificate Transparency logs.

Technology stack - detect the frameworks, CMS, analytics and tools running on the page you are viewing.

Portfolio and expiry alerts - track your domains and get a desktop notification before any of them expire.

Privacy first - no backend of our own. We never collect your browsing history. Only the domain you look up is sent, to public services. Everything returned is public record.

Free tier includes 5 lookups per day. Upgrade for unlimited lookups and pro tools.
