I am looking for something which u can selfhost and have a web UI or client where u choose the game and launch it. Edit: Something open source would be great!
Pterodactyl is probably the closest I’ve personally seen to what you’re looking for.
It depends what you are looking for. Your description is actually kinda confusing.
Do you want something to allow the install of games from a self hosted server? Then you’re looking for https://gamevau.lt
Do you want “one launcher to rule them all” that allows for local aggregation of all available games from all platforms? Then you’re looking for https://playnite.link
Do you want a front end for game servers? Then you’re looking for https://pterodactyl.io or https://cubecoders.com/AMP
Do you want something else? Give us a little more info and we can likely point you in the right direction.
https://pterodactyl.io/ here is one I’ve found when I was looking for the same thing, I havent tried it out myself but it looks alright
also https://alternativeto.net/software/pterodactyl/ here is some alternatives if you dont like pterodactyl that much or it doesnt work well
you mean https://gamevau.lt/?
I guess you want cloud streaming, like Google Stadia?
There are not many options there, but this seems the closest:
