Paste a URL to see what the site is built with: CMS or shop platform (WordPress, Shopify, Wix, Webflow, Drupal...), JavaScript framework (Next.js, Nuxt, Astro, SvelteKit...), hosting and CDN, web server, analytics, chat and cookie tools. Every result shows the evidence we found, so you can check it yourself. Free, no signup.
30 free checks a day. We read the page's HTML, headers and cookies the way a crawler does (no JavaScript).
We ran this checker on 23 home pages on 26 October 2026. Static site generators and builders announce themselves in a generator meta tag (with a version), frameworks leave their asset paths (/_next/, /_nuxt/), and the CDN shows in the response headers. Big sites with their own software often leave nothing to find.

We fetch the page once (following redirects) and match it against 86 fingerprints in four places: the <meta name="generator"> tag, response headers (server, x-powered-by, cf-ray, x-vercel-id...), cookie names (PHPSESSID, laravel_session) and script or stylesheet URLs in the HTML (/wp-content/, cdn.shopify.com, googletagmanager.com).
The same check runs over the Shotmint API, free with any key (500 checks a day, 0 credits), for lead lists, competitor tracking or audits in a spreadsheet:
curl -s "https://shotmint.creasework.com/v1/check?type=tech&url=wordpress.org" \
-H "X-API-Key: YOUR_KEY"
# {"type":"tech", "credits_used":0, "status":200, "final_url":"https://wordpress.org/",
# "technologies":[{"name":"WordPress", "category":"CMS", "version":"7.2",
# "evidence":"<meta name=\"generator\" content=\"WordPress 7.2-beta1-64729\">"}, ...]}To see the site itself, the API also renders it in Chromium: a website screenshot or screenshots of a whole list. More free checks: HTTP header checker, redirect checker, SSL checker, structured data checker.
