> Working as full stack devs, we constantly had to do this translation by hand. It was our least favorite part of our jobs, since the creative work had already been done by the mockup designer. It's so repetitive and mechanical that we decided to stop hand-coding divs and css and write a program to do it instead
This is definitely repetitive and annoying, just to add another data point to your own. I think people fundamentally want excellent WYSIWYG tools, it's just that the implementation leaves a lot to be desired usually (e.g. Frontpage). Really glad to see someone take another swing at this.
Quick nitpick: One of the links on your homepage ("Learn more") is broken (https://documentation.pagedraw.io/worfklow, looks like it's missing a trailing slash)
