Frequently Asked Questions about Webflow Detection
Find answers to common questions about detecting Webflow websites.
How can I check if a website is built with Webflow?
There are three reliable methods to check if a website is built with Webflow: Use our free Webflow Website Detector tool above by entering any URL for instant results. Alternatively, install our free Chrome extension which automatically identifies Webflow sites as you browse. For manual verification, right-click on a webpage, select "View Page Source," and search for Webflow-specific code markers like the HTML comment "This site was created in Webflow" or the meta generator tag.
What are the technical signs that identify a Webflow website?
Webflow websites contain four distinct technical markers in their source code: An HTML comment stating "This site was created in Webflow," a meta generator tag with content="Webflow", data attributes like data-wf-page, data-wf-site, and data-wf-domain, and JavaScript files loaded from Webflow's CDN at cdn.prod.website-files.com. Our detector automatically scans for all these fingerprints to provide accurate results.
Why would I want to know if a site is made with Webflow?
Knowing if a website uses Webflow is valuable for several reasons: Design inspiration to see what's possible with the platform, competitive analysis to understand what technology competitors are using, platform evaluation before starting a new web project, and business development for Webflow developers and agencies looking to identify potential clients who may need customization, maintenance, or migration services.
Can Webflow sites be detected even with custom domains?
Yes, Webflow websites can be detected regardless of whether they use a custom domain or the default webflow.io subdomain. The detection is based on code fingerprints embedded in the HTML source, not the domain name. These markers include Webflow's CDN references, data attributes, and generator tags that remain present even when sites are published to custom domains.
