You can export and even download a functioning .html! Does that help?

for sure, I guess I didn't see that UI button to export as html

Free so far

Try clicking "Choose Framework" or "Export Code". There you can find all the available formats to export =)

Gotcha, that wasn't obvious on mobile

The reason is that the mobile version doesn't include all the tools available in the desktop version. The mobile version is more of a 'light' or 'shortened' version, offering fewer features for a more streamlined experience.
