For managing my library on disk, I just recently made the effort to set up the *arr apps. I love having the metadata, tagging, organizing, and file naming all consistent and automated. Previously I used mp3tag and filebot to manage them and it was way more manual. Everything is set up with docker-compose and Ansible.
Library file stuff:
Two Radarr instances, one for 4k and another for lower resolutions
Sonarr for TV
Lidarr for music
Two readarr instances, one for epub/pdf and one for audiobooks
Jackett
deluge+openVPN
For library frontend stuff:
Jellyfin for movies, tv, music, audiobooks
Plex, for when Jellyfin is acting up
Jellyseer for TV & movie requests
LaunchBox for videogames and emulators
Calibre + calibreWeb for ebooks & syncing to my Kobo eReader
Haven’t set up yet:
flaresolverr
unpackerr
audiobookshelf
Doesn’t exist yet/wishlist:
*arr app for emulator ROMs (I’ll have to check out romm, looks pretty cool!)
