Technology Profiler
Detect the CMS, frameworks, analytics and CDN behind any website.
Point this profiler at any website and see what powers it — the CMS, JavaScript frameworks, analytics stack, CDN, caching layer and server software, grouped by category. For WordPress sites, dig deeper with the WordPress Theme Detector and check their hardening with the Security Headers Analyzer.
Frequently Asked Questions
How does the technology profiler detect what a site uses?
It fetches the page and matches 40+ fingerprints across the HTML source and response headers — CMS path patterns (wp-content for WordPress), framework markers (__NEXT_DATA__ for Next.js), analytics script URLs, CDN headers like cf-ray for Cloudflare, generator meta tags, and more.
What categories of technology can it identify?
CMS platforms (WordPress, Shopify, Wix…), JavaScript frameworks (Next.js, Nuxt, Angular, React…), libraries (jQuery, Bootstrap, Tailwind), analytics and pixels (GA4, GTM, Meta Pixel, Hotjar), CDNs (Cloudflare, Fastly, Vercel), caching layers, font providers, and the web server itself.
Why would I profile a competitor’s site?
Knowing a competitor runs WordPress + WooCommerce + Cloudflare tells you their cost base, their flexibility, and sometimes their weaknesses. Agencies also use profiling to scope migration quotes before a discovery call.
Is the detection always complete?
No tool sees everything — heavily bundled or server-rendered sites hide many client-side clues, and some platforms deliberately strip identifying headers. Treat results as strong signals rather than an exhaustive inventory.
