Jellyfin: The Free Software Media System

I just made the switch from Plex a few weeks ago. Overall, I like the UI of Jellyfin better and haven’t had any difficulty playing media that I played on Plex. Once MFA and offline sync are added to Jellyfin, I won’t miss Plex at all.

I used Plex for a long time, switched to Jellyfin a few years ago. If it's not equally as good it's better.

I have also had a lot less trouble with containerizing it and settings being reloaded after a rebuild but that may just be me.

Plex still wins on client compatibility, ease of server & client setup, and at least has the 3 commonly used oidc login providers available.

Jellyfin you may need to point external clients to your server manually as well as setup everything so they can actually connect. There are so many ways to do this that it can be paralyzing to actually decide which to try as a beginner. Local clients can usually use discovery if the firewall and container are setup correctly for the jellyfin server. Accounts have to be created manually unless you use something like jfa-go. For oidc, there's only 3rd party plugin in alpha state and looks like people use it so guess it works well enough.

As others have said, you can have both running on the same system pointed at the same content. If you're following the plex naming scheme should match pretty well in jellyfin, nfo files work really well for jellyfin metadata too. Lets you get an idea of it and whether it could meet your needs.

I mostly switched to Jellyfin over 3 years ago, shutdown my plex server 2 years ago after many tiny annoyances over the years. I had tried to get my family switched over but it is too much hassle for them and myself still. Been working on setting up some cheap htpc's for that purpose but it's not a priority for me.
