wpgraft never reads Webflow’s data. There is no exporter, no importer and no shortcode translator anywhere in this, by design, because those are the parts that break. wpgraft reads the page as your browser rendered it: the real elements and the real computed styles on each one, at every breakpoint you ask for. It then rebuilds that as Gutenberg’s own native elements, with the styles written into Gutenberg’s own fields. Nothing that arrives depends on Webflow still existing.
People leave Webflow for WordPress over hosting cost, CMS limits or client hand-off, and the design is the part they do not want to lose. Webflow has no WordPress export, and the HTML export it does have gives you a folder of files, not a page you can edit. wpgraft copies from your published Webflow site, an ordinary web page, and rebuilds it as core WordPress blocks. Your Webflow project stays live the whole time.
