Codeberg is only an alternative for FOSS software.
Most of my GitHub stuff for example is private client projects that I cannot simply publish. They don’t provide much value to others and might contain proprietary code. The same goes for private half finished side projects that I‘m sure most people have on their accounts. Codeberg is simply not the right place for this.
Yep I used that in university for generative art. It was a lot of fun and actually got me into coding unlike many failed attempts before that.
