WhatStack wót Aditya Srivastava

WhatStack is a browser extension that instantly detects and displays the tech stack of any website you visit. With one click or keyboard shortcut, it reveals frontend frameworks, backend languages, CMSs, and other technologies used on the site. Whether it's React, Vue, Node.js, PHP, or WordPress, WhatStack analyzes the page using browser APIs and public data—without tracking or sending information to external servers. It's fast, lightweight, and ideal for developers, designers, and tech enthusiasts curious about how websites are built. WhatStack runs entirely in your browser and supports a wide range of sites with a clean, user-friendly popup interface.
