See what a site is built with: Webflow features, class system, libraries like GSAP and Finsweet, analytics, cookie tools, embeds and fonts.
Site address
Good to know
What it can and cannot see.
Only this page
It reads one page's code. Features used on other pages will not show until you check those pages.
Webflow-specific
It spots CMS lists, interactions, forms, Lottie, localization and whether the site uses MAST or Client-First naming.
Useful before a project
Check a site before quoting, so you know about memberships, scripts and add-ons early.
