Webflow Checker is a lightweight browser extension that instantly identifies whether any website was built using Webflow, displaying a visual indicator in your browser toolbar.
For Webflow developers and designers, this tool serves as a quick reference for competitive research and inspiration gathering. When you encounter a site with impressive interactions, layouts, or animations, Webflow Checker lets you immediately verify if it's a Webflow build—helping you understand what's achievable within the platform and potentially reverse-engineer techniques for your own projects. It's particularly useful during client discovery calls when analyzing existing sites or competitor landscapes, allowing you to quickly assess whether a reference site shares your tech stack. The extension also streamlines the process of building showcase portfolios or case study collections, as you can rapidly identify and catalog Webflow sites worth studying.
Unlike manually inspecting page source or searching for Webflow-specific class names, this extension provides instant, one-click verification with a clear visual indicator (blue and green checkmark), saving valuable time during research sessions.
Ideal for freelance designers seeking inspiration, agencies conducting competitive analysis, and developers learning advanced Webflow techniques by studying real-world implementations.
```Webflow Checker is a Chrome extension that instantly identifies whether a website was built with Webflow. Install the extension, then click its icon when viewing any site—a blue and green checkmark confirms the site is built in Webflow, while an X indicates it's not.
Quickly identify Webflow sites for inspiration, competitive analysis, or client prospecting. It saves time compared to manually inspecting code, and helps you discover well-designed Webflow examples to learn from or share with clients as portfolio references.
Verify if competitor sites use Webflow, build inspiration libraries of Webflow-built sites, identify potential client leads who might need Webflow services, and quickly validate whether a site you admire is feasible to recreate in Webflow's platform.
Webflow Checker is highly accurate as it detects Webflow's specific code signatures and hosting patterns. However, heavily customized sites or those using proxies might occasionally produce false negatives. It remains one of the most reliable ways to identify Webflow sites at a glance.
