MS Stack Detector

See what any website is built with: CMS, theme, plugins, e-commerce platform, frameworks, analytics and more. Private, runs locally.

MS Stack Detector shows you what a website is built with, in one click. Open any site, click the icon, and see the technologies behind it, grouped into clear categories. What you see: - The platform or content management system the site runs on - For WordPress sites: the active theme and the plugins found on the page - For Shopify stores: the theme name - The JavaScript frameworks and libraries the page uses - Analytics, advertising and marketing tools loaded on the page - Payment providers, chat widgets and other third-party services - Hosting, CDN and server hints, plus common security headers Why people use it: - Check what a competitor's store is built on - Find the theme and plugins of a WordPress site you like - Audit which tracking tools a page loads - Copy a plain-text report of any site's stack with one button Private by design: - Works only when you click the icon, only on the tab you are looking at - Everything is analysed locally in your browser - No accounts, no tracking, no data sent anywhere - Needs only the "activeTab" permission, no access to all your websites Note: server-side technology (databases, back-end frameworks) is not always visible from the outside, so some sites will show less. Detection is based on public signals in the page and its response headers. Built by MatrixInn Solutions.
