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. The popup matches Webflow's fingerprint signals (response headers, asset URL prefixes, runtime globals, sourcemap paths) and flags it whenever any combination 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.
