Cloud variables could be supported with this (extremely simple) Javascript library that seems to be very Scratch-inspired: https://kihtrak.com/cloud_variable/

Looking through the author’s other projects, it appears that he’s a lifelong Scratcher. 😃

The code for the client is quite minimalistic, and the server code isn’t much larger. We could either link to this project or copy / adapt it more wholesale – there is no license attached to the code, so we may want to inquire about it.
