Hey,
I know it sucks to rely on cloud services but it is what it is. I use Apple iCloud, Bitwarden and GitHub.
Technically, I could self-host all three but I want my backups not at my place or at least have them in both places cloud/at home.
I do have two spare Raspberry Pi Zero 2W and one small computer with an old i5 / 8 GB RAM.
What do you personally self-host?
FWIW, other public git instances exist. As in alternatives to github. No need to selfhost.
You can host git anywhere you have ssh or https. I don’t know if you can push over https though.
I know that. My point is: you don’t have to.
