## About

WhosBuilt checks public signals across a domain's HTML, DNS records, SSL certificate, registrar data, technology fingerprints, and hosted metadata.

Use it to identify hosting providers, frameworks, analytics tools, CDN infrastructure, WHOIS registration details, creator credits, and about-page ownership clues.
