Understanding a website's technology stack reveals its architecture, potential attack surface, and the tools powering its user experience. Whether you're conducting competitive research, performing a security due diligence audit, or evaluating a potential technology partner, knowing what a site runs under the hood is actionable intelligence that can inform your own technology decisions.

The Technology Stack detector analyzes HTTP response headers, JavaScript bundle signatures, HTML meta tags, and DOM patterns to identify the frameworks, CMS platforms, analytics tools, CDN providers, and server technologies in use. It detects over 1,500 technologies across categories including JavaScript frameworks (React, Vue, Next.js, Angular), CMS platforms (WordPress, Shopify, Drupal, Webflow), analytics and marketing tools, and hosting infrastructure — giving you a complete picture of any website's technical footprint.
