It’s fairly simple actually, the basic idea is to create multiple desktops from a single host; fully HW accelerated and isolated from each other. So for example I could stream a game to my couch TV whilst someone else is playing a different game on the very same computer.

Personally I use this on my homelab: the same machine that has got Jellyfin (and other containers) installed can share the GPU with Wolf so that I can both transcode with HW acceleration when needed and play a game or open up a remote desktop all from one single machine.

Not fully open source and trying to get paid subscriptions even before having a product doesn’t sound too good to me…
