What is thatsite built with?
Paste any URL and we'll reveal the tech behind it, framework or CMS, hosting and CDN, analytics, fonts, and e-commerce. Yours or a competitor's. Instant, free, no email required.
A peek under the hood.
We read the page's markup and response headers and fingerprint the technologies powering it, the same signals real developers look for.
Framework
& CMS
Next.js, WordPress, Shopify, Wix, Webflow, Squarespace, Framer and more.
Hosting
& CDN
Vercel, Netlify, Cloudflare, CloudFront, Fastly, where the site actually lives.
Analytics
& tools
GA4, Tag Manager, Meta Pixel, fonts, Stripe and other tracking & commerce tools.
Why look under the hood?
Knowing what a site runs on tells you a lot, whether it'll be fast, whether it can grow, and whether it's boxed into a page builder. Check your own, or size up a competitor.

Questions, answered.
Yes, completely free, no email or signup. Paste any public URL and we instantly fingerprint the technologies powering it across framework/CMS, hosting/CDN, analytics, fonts, and e-commerce.
It fetches the page like a browser would and pattern-matches well-known signatures in the HTML, scripts, and HTTP response headers, for example /_next/ for Next.js, /wp-content/ for WordPress, an x-vercel-id header for Vercel hosting, or googletagmanager.com for Tag Manager.
Yes, that’s one of the most popular uses. Enter any public URL to see what framework, host, analytics, and commerce tools a competitor relies on. It only reads what the site already sends to every visitor; nothing private is accessed.
Some sites are hand-built, heavily customized, or behind a bot-blocking layer, so there’s no obvious fingerprint. That can actually be a good sign (a lean custom build). It can also mean the site blocked our request.
The stack shapes speed, flexibility, and cost. Page builders like Wix or Squarespace are quick to start but get slow and boxed-in as you grow; a modern custom build (e.g. Next.js) tends to load faster, rank better, and bend to whatever you need next.
We build custom sites on a modern stack, typically Next.js and React, hosted on fast edge infrastructure, with SEO and performance baked in. If your current stack is holding you back, that’s exactly the kind of move we help with.
