Shipped this project!
I built an alternative free and open source Cloud gaming Software, wich runs any game (as long as its runnable via wine OR Linux native) in docker containers and streams the gameplay to the User in the browser and returns the inputs, and everything (exept the html files) completly in C!
It was Not an easy projekt and i learn way too mouch from thread safety, docker managment, http/https servers in c, Password security using sodium, user and database managment using sqlite3, and way more C stuff than I already knew!
