The short answer
- Choose Plex if you want the easiest setup, family outside your home watching your library, and are fine paying for remote video and hardware transcoding.
- Choose Jellyfin if you want every feature free, no outside account, and are happy to set up remote access yourself.
On an Apple TV at home, the app you watch in decides the picture and sound more than the server does.
What each one costs
Plex
The server and the apps are free on your home network. Plex Pass is $6.99 a month or $69.99 a year in the App Store, or $749.99 for life from plex.tv. It unlocks hardware transcoding and lets you, and everyone you share with, watch video away from home. Without it, a viewer can buy a Remote Watch Pass for $2.99 a month or $29.99 a year.
Jellyfin
Free and open source, with no paid tier. Hardware transcoding, remote access, Live TV and recording through a tuner are all included.

Watching away from home
Plex reaches your server from outside through its own connection service, and falls back to a relay when a direct route fails, so it usually works without touching the router. Since April 2025, remote video needs a Plex Pass on the server owner’s account or yours, or a Remote Watch Pass on yours. Plex counts any connection that is not on the server’s own subnet as remote.
Jellyfin leaves remote access to you: forward a port, put it behind a reverse proxy with a certificate, or use a private network such as Tailscale or WireGuard. It costs nothing, and it takes an evening the first time.
Accounts and privacy
Every Plex user signs in with a plex.tv account, and the apps link through it. That is what makes sharing with family easy, and it means Plex’s servers take part in every sign-in. The official app also carries Plex’s own free streaming channels and ads alongside your library.
Jellyfin accounts live on your server and nowhere else. Nothing outside your network knows what you have or what you watch.
On the Apple TV itself
An Apple TV 4K decodes H.264 and HEVC in hardware, including 4K Dolby Vision, HDR10 and HLG, and HDR10+ on the 2022 model. When the app asks for the file as it is, either server sends it without transcoding and the server’s processor stays idle, so transcoding power only matters for remote viewers on slow connections and for formats the app cannot play.
What the app does with the file is where the two experiences differ: whether it switches the TV into Dolby Vision, how it handles TrueHD and DTS audio, and whether it plays a film at its own frame rate. On the Apple TV, turn on Match Dynamic Range and Match Frame Rate under Video and Audio whichever server you run.
The Apple TV apps for each
Plex: the official Plex app, which began rolling out a redesign on Apple TV in September 2026, and Infuse, UHF, IPTVX and Spectati.
Jellyfin: Swiftfin, the project’s own free client, plus Infuse, Streamyfin, Moonfin, UHF and Spectati. The Jellyfin client round-up compares them.
Running both
Plenty of people do. Both servers read your files where they are and keep separate databases, so they can share the same library folders on one machine. A common setup keeps Plex for family members who already have its app and Jellyfin for yourself.
Two servers usually mean two apps on the Apple TV. Spectati shows both as one library with one search and one Continue Watching row, merges a film that is on both into a single entry, and plays it from the server you put first. Plex and Jellyfin in one app shows how.
