Website Technology Checker

What CMS Is This Website Using?

Enter any URL and instantly discover its technology stack. The Website Technology Checker identifies over 30 technologies across five categories: content management systems, JavaScript frameworks, web servers, analytics platforms, and front-end libraries.

How It Works

The checker fetches the target website's HTML source and HTTP headers, then runs pattern matching against known technology signatures. WordPress sites expose wp-content paths. Shopify loads from cdn.shopify.com. Next.js embeds __NEXT_DATA__. Server headers reveal Nginx, Apache, or Cloudflare. Each detection includes a confidence level based on signal strength.

Why Check a Website's Technology?

Understanding what a site is built with helps developers evaluate platforms, competitors research tech stacks, and businesses make informed decisions about their own website infrastructure. Whether you're choosing a CMS, analyzing a competitor, or auditing your own site, knowing the underlying technology is the first step.
