> Current solutions like Docker, Sandstorm, Cloudron, command line scripts etc. are "easy" for developers but not for ordinary users. What is easy for ordinary users? Installing a web app by uploading files to a folder on a server using a GUI FTP app is one example for PHP.

Eh? Installing an app on Sandstorm or Cloudron is basically the same UX as installing an app on your phone. Certainly much easier than uploading files to an FTP server.

I agree with your comment with regards to Docker and CLI.

I'm also happy to agree that Sandstorm and Cloudron hosts are much less ubiquitous than PHP hosts, and that's a real blocker to ordinary users... but it seems weird to classify them as developer-oriented on that basis?
