stupid question I know but let me explain. I self host only because I love learning random things and this was just another thing that I convinced myself I needed to learn, not out of necessity. I am hosting an *arr media system right now but that is pretty much the only thing I actually need, I have unlimited google photos so I don’t need Immich, I am happy with bitwarden so I don’t need vaultwarden, don’t need home assistant, nextcloud, bookstack etc so what I should I self host? throw any idea you have at me.
Well, YMMV may vary and seems to from the above. But for me self-hosting, especially on home machines, is largely about privacy and reduced cost as well as learning. Google in particular will hover up all data possible and profile you to hell and back selling the results. I used to use Dropbox and a higher price plan to get their [dubious] encryption and so on until I realized I could meet all my needs and more data across multiple machines with a NAS or NFS among other solutions.
