wpgraft reads the page as your browser rendered it, every element and the computed styles on each one, at every breakpoint you ask for, and rebuilds it as Webflow’s own native elements with the styles in Webflow’s own fields. It needs no access to your Framer account, no export file and no API key. If Chrome can draw the page, wpgraft can copy it.
Both ends are design tools with their own hosting, and neither will read the other’s file. wpgraft goes through the rendered page: it copies your published Framer site and hands it to the Webflow Designer through Webflow’s own clipboard format, so what lands is native Webflow elements with real style classes.
