I think one could use Github&#x27;s electron (on which Atom is based) and one of the open source WYSIWYGs (possibly tweaked) to get the standalone app you seem to be indicating. Taking one of the slimmer SSGs and packaging it alongside still may result in quite a large binary (not sure).<p>As for hosting, Amazon&#x27;s s3 seems the most appropriate. While you could automate domain registration and DNS records, I&#x27;m not sure how.<p>This seems like it could be an interesting project.
