What is Webflow?
Webflow is a visual website builder that also hosts sites and generates clean code.
Signs a site uses Webflow
- A generator tag naming Webflow. Webflow adds it to published sites.
- data-wf-page and data-wf-site attributes. They sit on the html element of Webflow pages.
- assets.website-files.com or cdn.prod.website-files.com in file addresses. Webflow serves images, styles and scripts from these domains.
How to check by hand
View the page source and search for data-wf-site. Sites on the free plan also use an address ending in webflow.io.
What can hide it
A site exported from Webflow and hosted elsewhere keeps much of its markup, so these signs show it was designed in Webflow, not that it’s hosted there. A negative result doesn’t prove a site isn’t using Webflow, because the checker reads the page source and response headers, and tools loaded later by JavaScript may be missed.
Check the rest of the stack
Paste the address into the Website Technology Checker to see the platform, framework, analytics and more in one report. To see where the site runs, use Who Is Hosting.
Website Technology CheckerFind out what any site runs on: CMS (WordPress, Drupal, Joomla, Ghost, Webflow, Wix, Shopify), forum software (vBulletin, XenForo, phpBB, Discourse), frameworks (Next.js, Nuxt, React, Vue), server and CDN, analytics and more — with versions when the site shows them.
Open the tool Frequently asked questions
How can I tell if a website uses Webflow?
Enter the address in the checker above, or view the page source and look for: A generator tag naming Webflow.
Is the Webflow check always accurate?
A match is a strong sign, but no outside check is certain. A site exported from Webflow and hosted elsewhere keeps much of its markup, so these signs show it was designed in Webflow, not that it’s hosted there.
How do I see which classes a Webflow site uses?
Open your browser’s developer tools and inspect an element. Class names appear as written in the Designer.
