Just posting to say that I agree with the parent comment. All my sites have so much additional stuff that I couldn't just rely on somebody else's hosting even if your hosting is going to be fast and use use CDN to cache images. Maybe I want to host on Vecel to integrate their analytics or their other plugins, or I want to host on Github pages to link it to my repo. Or I want to move additional files in there and be able to access them via SSH.

Offering hosting is good, but if I pay for the service not being able to download as html / css feels like being held hostage. Instead, you should be up front about it (your software is a editor) and offer things like auto push of changes to GitHub so that I don't have to manually export.
