Honest limitations

This profiler reads what the server publicly exposes. Sites that strip fingerprints, bundle everything behind JavaScript, or proxy through multiple layers may show fewer technologies than a browser extension would. Versions appear only when the site exposes them. Results are a snapshot of the homepage at profile time.

FAQs

What does the technology profiler detect?

80+ widely-used web technologies: content management systems (WordPress, Shopify, Wix), JavaScript frameworks (React, Next.js, Vue), analytics (Google Analytics, Hotjar), CDNs (Cloudflare), payment processors (Stripe, PayPal), web servers, programming languages and more.

How accurate is the detection?

Detection uses server response headers, HTML fingerprints, script URLs and meta tags — the same signals professional profilers use. Sites that hide fingerprints or render everything in JavaScript may show fewer results. Versions are reported when exposed.
