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?
You found a solution and you are looking for a problem.
This is not the way it goes. You identify a problem, and if the solution involves self-hosting then you solve it with self-hosting.
This.
