FAQ
How does it work?
The tool resolves DNS A and CNAME records, performs reverse DNS on the IP, and checks HTTP headers (Server, X-Powered-By, Via). Each signal is matched against fingerprints of 30+ providers to determine who hosts the site.
Why does it show Cloudflare instead of the real host?
When Cloudflare's proxy is active, all public signals (DNS, headers) point to Cloudflare. The tool reports what's publicly visible. The origin host is hidden behind the proxy.
Does it call external APIs?
No. Everything runs on our server using Node.js built-in DNS and standard HTTP requests. No WHOIS, no third-party lookups.
