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?
Everything starts with what my family needs/uses. Jellyfin for media. Grocy to track which kid has done their chores. Home assistant to make a nice dashboard in the kitchen to see the family calendar (still on google) and the chores. I’ve tried a few other things, but those are the ones important to me.
