I have gone down the self-hosted rabbit hole, like many it all started with setting up a pihole on a raspberry pi.

I have since gone down the jellyfin + arr stack route. Resource wise the entire stack uses very little. I have Sonarr, Radarr, Prowlarr, Bazarr, FlareSolverr, Jellyseerr, SABnzbd, qBittorrent, Gluetun, qui, Decluttarr, Recyclarr, arr-dashboard all running on my dell optiplex (previously on the raspberry pi).

All up this uses about 2GB of RAM and 0.5% CPU.

I found it extremely fiddly to set up, understand what each component does and have everything integrated well across all my devices.

Without the help of an AI assistant I just wouldn't have had the time to debug every little issue. It took me a good 12 months of tinkering around work hours to have everything stable. However now it runs along fine with very little intervention and I'm able to share it with friends and family.

So the resource argument I don't think is valid. However the fiddly mess I do agree with. Although personally I found it fun and rewarding when things finally worked. But I can understand why people would not want do spend all that time on it.
