Domain Analysis

Inspect any domain's registration, DNS records, SEO tags, and technology stack in one view. Results come from live RDAP, DNS, and a single homepage fetch — no tracking, no accounts, no rate limits.

Try:

Registration

RDAP lookup for the authoritative WHOIS data: registrar, creation date, expiration, status codes, registered nameservers, and the registrar's abuse contact. Registrant details are usually redacted under GDPR and privacy proxies — we surface that explicitly instead of pretending.

Meta / SEO

Parses the homepage HTML for the tags that matter: page title, meta description, canonical URL, favicon, all Open Graph properties, and Twitter Card fields. Renders a live preview of the og:image — the picture that appears when someone shares the link in Slack, iMessage, or Twitter.

System

Fingerprints the stack from HTML signatures and HTTP headers: WordPress, Next.js, Shopify, BigCommerce, Adobe Commerce, Webflow, Squarespace, Drupal and more. Detects the CDN or proxy layer (Cloudflare, Vercel, Fastly, Akamai, Netlify, AWS CloudFront). Also fetches robots.txt and sitemap.xml with collapsible previews.

DNS Records

Live DNS from a public resolver: NS, A/AAAA, CNAME, MX, TXT, SOA, CAA. Extracts SPF and DMARC records from TXT, then probes common DKIM selectors (default, google, selector1, selector2, k1, mail) to surface the email-auth setup. Compares live nameservers against the registered set to flag propagation or transfer issues.

What you get back

Why RDAP instead of WHOIS?: RDAP (RFC 7483) is the modern HTTPS+JSON successor to port-43 WHOIS. It returns structured data directly from the registry, which is faster and more reliable than scraping WHOIS text. We route queries through the IANA-published registry map, falling back to rdap.org if a registry is slow.
Why are some contact details blank?: Registrars have been redacting registrant name/email since GDPR took effect in 2018. The abuse contact stays public by ICANN mandate — that's usually your best real email for reach-out.
How are platforms detected?: One HTTPS request to the homepage, then a scan of the response headers and HTML body for known signatures: wp-content for WordPress, __NEXT_DATA__ for Next.js, cdn.shopify.com for Shopify, and so on. Same request feeds the meta-tag parser, so it's one fetch across two cards.
