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?
Just get a vps it still counts as self hosting if you run all the software yourself.
I have an expensive VPS at AWS which I mainly use to host my projects :D
Plenty of cheap VPS at https://lowendbox.com/. I have several test VPS that run me $25 a year.
Get a cheap one on lowendspirit.com instead.
Try netcup instead.
