What Technology Does a Website Use?

Our free technology lookup tool scans any website and identifies the technologies behind it β€” including CMS platforms (WordPress, Shopify, Webflow), JavaScript frameworks (React, Next.js, Vue), CDN providers (Cloudflare, Fastly), analytics tools (Google Analytics, Plausible), and more.

How It Works

We analyze the website's HTML source, HTTP response headers, JavaScript files, and meta tags to identify technology fingerprints. This is the same approach used by tools like BuiltWith and Wappalyzer, but completely free and with no login required.
