How CRFT Lookup Works Its Magic
So, how does CRFT Lookup play CDN detective? It’s like a cyber bloodhound, sniffing out DNS records, HTTP headers, and technical signatures. With a database of over 2,500 technology fingerprints, it fires up a headless Chromium instance to scan any URL you toss its way. In a flash, it IDs CDNs like Amazon CloudFront, Fastly, or Cloudflare, plus other tech like frameworks and analytics tools.
Plug in a website’s URL, and CRFT Lookup hunts for CDN clues left in public-facing infrastructure. It’s not just about CDNs, though—this tool can dissect any site, from TailwindCSS to Stripe, delivering a crisp tech stack breakdown that’s a breeze to read.

The Fine Print on CDN Detection

For the full scoop, you’ll need to research the CDN yourself—CRFT just gives you the starting line.
Its detection is sharp, thanks to a constantly updated engine that cross-checks multiple indicators. But it can only spot CDNs with public-facing components—custom or super-private setups might slip through the cracks.
