Thanks for the quick reply! The use-case I'm thinking about is as follows: we create a 'template' single-page website for a niche market β eg., 'dentists', or 'business coaches'. Using Webstudio, we can make the template easily adaptable by using CSS and data variables. We could then do an email campaign that would invite our target audience to come over to our site, answer a few questions, which would then duplicate our 'template' site and populate the variables for us. Of course, further customisation might be possible β eg. adding/removing pages and sections, replacing fonts and media assets, etc. β depending on the capabilities of the API.
There are some website builder platforms that are starting to focus on this kind of capability:
