Website Technology Checker
Find out which CMS, frameworks, analytics, CDN and server a website uses.
About the Website Technology Checker
Curious which platform a competitor runs on, which analytics tools a site uses or whether a page is built with React? This checker reads the page source, scripts and HTTP headers and matches them against fingerprints for popular content management systems, e-commerce platforms, JavaScript frameworks, analytics and advertising tools, CDNs and web servers.
Detection is based on public signals, so it can miss technologies that leave no trace in the HTML or headers, and sites can deliberately hide them. It is a quick first look, not a full audit.
Frequently asked questions
How does technology detection work?
Each tool leaves fingerprints – file paths like /wp-content/, script URLs, meta generator tags, cookies or response headers. The checker looks for those patterns.
Which CMS is best for SEO?
Any modern CMS can rank well. What matters is fast hosting, clean templates, control over titles, URLs and redirects, and good content. WordPress, Shopify, Webflow and headless setups all work.
Why was a tool not detected?
Some tools load only after user interaction or through tag managers, and some sites remove identifying markers.
