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?
Back when I first started with NextCloud, it was pretty unresponsive on the web front end for my ebook collection, which was a ton of small files. It’s gotten a whole lot better in the last year or so. Now, I don’t worry about it. This is also with a very badly set up copy. I’m sure that a proper install would work much better, too.
