Just checked and you are right.

AFAIK Proton has a free tier.

I’ve set up navidrome a long time ago, way before I’ve started using Jellyfin. And it just runs like a charm paired with some great clients for the subsonic ecosystem. So honestly it never even occurred to me to use Jellyfin for music.

Just from the top of my head:

• Navidrome (Music)
• Audiobookshelf (Audiobooks)
• Paperless-ngx (documents)
• Joplin (notes, lists and more)
• Komga (comics)
• Mealie (mealplanner, recipes, shopping lists)

Edit: I left out some stuff that you or others already mentioned. But here’s the extended list so I can copy/paste this if someone else asks in the future.

• Immich (photos)
• Home Assistant (home automation)
• Jellyfin (Movies, TV series and more)
• Calibre & Calibre-Web (ebooks)
• Pi-hole (DNS sinkhole)
• Vaultwarden (password manager)
• Nextcloud (data sharing)
• Homarr (Dashboard)
• Headscale (Tailscale Server)

Honorable mention:

• Proxmox (Hypervisor)
• Portainer (Container Management) - I know a lot of people wouldn’t recommend it for various reasons, but works alright for me

In order of personal preference:

1. Jellyfin Mobile
2. Infuse
3. Streamyfin
4. Swiftfin

Maybe just try them all out and find the one that fits you best. You could also use more than one (which is what I do).

Big fan of Feishin!

For iOS I’ve always used play:Sub, but will give Amperfy a try!
