Dig into any domain!

What we dig

Full-stack domain intelligence, in seconds.

Paste any domain and FatDig pulls together everything you need to know — ownership, configuration, performance, and security — in a single click.

WHOIS & Registration

Registrar, registrant dates, nameservers, status flags, and abuse contacts — queried live from the authoritative registry.

DNS & Routing

A, AAAA, MX, NS, TXT, CNAME, SOA records. Plus probes for common subdomains so you spot mail and admin endpoints fast.

SSL & Headers

Certificate issuer, SANs, validity window, signature type, plus the full HTTP and HTTPS response headers for the host.

Performance

Google PageSpeed Insights score, Core Web Vitals, and the highest-impact opportunities to improve load time and UX.

How it works

Three steps. One unified report.

  1. 01

    Paste a domain

    Any hostname works — root, www, or any subdomain. FatDig handles the parsing.

  2. 02

    We dig in parallel

    WHOIS, DNS, SSL, redirects, headers, and performance run together — not back-to-back.

  3. 03

    Read or share the report

    Inline summary in the modal, or open the Advanced Dig for charts, copy-buttons, and a print-ready report.
