Webflow
Webflow is Software-as-a-Service (SaaS) for website building and hosting.
What detecting Webflow tells you about a site
Webflow is a visual web-design tool that exports and hosts production sites without hand-written code. Its fingerprints are clear: the Webflow generator meta tag, data-wf-* attributes and .w-* utility class names (w-nav, w-container) in the DOM, and assets served from *.website-files.com / assets.website-files.com. Spotting it tells you a designer- or marketing-led team built and hosts the site entirely inside Webflow — common for marketing sites, portfolios and startups that wanted pixel control and a CMS without an engineering pipeline.
Webflow in a real-world stack
When you find Webflow, it rarely travels alone. Self-contained hosting and CMS; interactivity comes from Webflow's own interactions engine, occasionally extended with custom embed scripts.

Quick facts
How we detect Webflow
Sourcemap Explorer carries 4 fingerprint signals for Webflow, spread across 3 channels — meta tag, javascript global and dom selector. The exact patterns are listed below, and you can replay each one in Chrome DevTools to confirm a match by hand.
Each signal alone is rarely conclusive — Sourcemap Explorer cross-references all of them and weights by confidence. You can reproduce any of these checks yourself in Chrome DevTools.
<meta> tag injected into the document. Visible by viewing the page source.
<meta name="generator" content="Webflow">
Window-level global the technology installs on page. Reproducible by typing the path into the DevTools console.
window.Webflow
window.Webflow._.VERSION = ([\d.]+)
A DOM selector that only this technology's pages render. Verified at runtime by the content script.

FAQ
How do I check if a website is using Webflow?
Open the page in Chrome, click the Sourcemap Explorer toolbar icon, and read the Stack tab. Webflow's specific fingerprints here are meta tag, javascript global and dom selector, and the popup flags Webflow whenever any combination of them is found. The same checks can be reproduced manually in DevTools — see the "How we detect" section above.
What Webflow version can Sourcemap Explorer detect?
Webflow ships as a hosted page builders rather than a bundled npm package, so version-specific detection isn't always possible. Where the platform leaks a version in response headers (`X-Powered-By`, `Server`, generator meta tags) we surface it; otherwise we report presence only.
Is Webflow a SaaS or self-hosted?
Webflow is offered as a hosted SaaS product. Detection runs against the JavaScript SDK or asset-URL fingerprints the platform ships into pages.
How much does Webflow cost?
Webflow's pricing model is documented as: freemium, low, recurring. Detection is independent of the pricing tier — Sourcemap Explorer flags the technology by its fingerprints, regardless of which paid plan a site is on. See the official site for the current pricing page.
