The Webflow Website Detector is a free Chrome extension designed to quickly identify whether a website is built using the Webflow platform. This tool automatically scans every tab you open and updates the toolbar icon in real-time, providing instant feedback. Users can easily see if a site is built with Webflow through a clear 'built with Webflow' or 'not built with Webflow' verdict, making it an essential tool for developers and designers alike.

In addition to its primary function, the extension confirms Webflow-specific assets, attributes, and runtime globals, ensuring accuracy in detection. Operating entirely within the browser, it prioritizes user privacy by avoiding tracking or data collection. The polished user interface, which includes dark-mode support, enhances the overall experience, making it visually appealing and user-friendly.
