If you're developing games, where do you host your code repositories (if there are any)? And why?
If you want, you can also share thoughts and experiences with hosters in general.
I never paid a penny for code hosting in my life.
For me, I host my projects on Codeberg.org. Codeberg.org is my absolute favourite right now. The people who run it are aggressively pro-free software and its run by a nonprofit so it's unlikely they will turn to the Dark Side. Supports Git and has an interface that is near-identical to GitHub. Has an issue tracker, pull requests, a wiki feature, which is already enough for me. I always disable the wiki, I like readmes more. :D On this server there are my important game projects as well as most of my mods for Minetest.
I recently started using Codeberg Pages which is a simple git-based webhosting service for static webpages. So far, I put a game manual and my personal website on it.
It's very obvious they want to clone GitHub, but in a good way and they want to go FULL free software mode. I think having a GitHub-like interface is strategically a good idea because this could help curing the free software community away from its terrible GitHub addiction.
Should I ever manage to climb out of poverty, I might even start to throw a buck or two at them. But I'm grateful they offer this service to the public, for free.
Rarely, I use other code hosters, but pretty much only for bugreporting. GitLab is one example. Also, none of my own projects are here.
A special case is Hedgewars (which is not "my" repository but I helped bring Hedgewars to 1.0.0), which uses a self-hosted Mercurial repository. Self-hosted code repos are a rare sight these days.
