What Webflow is
Webflow is a visual development platform that produces static HTML, CSS and JavaScript and hosts it on its own network. Because the output is generated by the Webflow designer, every published page carries the designer's own attributes in its markup.
How DNSTrace.dev detects it
Detection reads the final HTTPS response and the first bytes of its markup. One matching signal is reported as strong evidence; two or more independent signals are reported as confirmed.
data-wf-page in markup— The Webflow page identifier written into the document element of every published page.assets.website-files.com in markup— The Webflow asset host for images and uploads.CNAME targets under webflow.io— The staging hostname a published project is served from before a custom domain is attached.
What a detection proves
The page was generated and published by Webflow.
What it does not prove
Whether Webflow also hosts it. Webflow output can be exported and served anywhere, so the markup attributes can appear on a site delivered by another platform entirely.
Common questions
Can Webflow markup appear on a site Webflow does not host?
Yes. Exported Webflow code keeps its attributes, so DNSTrace.dev reports the delivery platform separately rather than assuming Webflow hosting.
Is data-wf-page reliable?
It is written by the publishing pipeline into every page, so it is present unless the markup has been post-processed.
