FYI That setting seem to be in Settings > Network under "List of IP addresses and networks that are allowed without auth"

I had no idea this was there :/

I remember trying this, and could still not get it to work. :(

I sincerely tried to disable cloud login, and could not figure out how.

Same

You can either navigate all the dark patterns Plex has put and will put in the way to force you to pay, or you can simply install Jellyfin and ditch Plex. I did the last.

Sure, except despite the dark patterns the actual experience of using Plex is much better than Jellyfin.

I have a smallish 100TB library I'd really love to move away from Plex, I regularly test out Jellyfin to see if they've finally made it usable. But sadly Jellyfin is still very far from being a good Plex replacement, it's just janky as fuck.

Constant playback errors, terrible client support, significantly higher resource usage.

100TB is not smallish. Here I was, thinking my setup of 8TB was small... What's your hardware? And, if you don't mind me asking, how is that you are using so much space? 4K movies? Honestly curious.

I have paid though and it was money well spent. I've mostly praised Plex because managing my media was a source of constant stress.

I still think Jellyfin is interesting and I'm going to keep it running alongside Plex to trial it.

Thank you for the extremely valuable edit! I am going to try it now too.

They’re easy to spin up in a Docker too.

Linuxserver.io hosts containers for Plex, jellyfin, and a bunch of related apps, with example compose or shell scripts.
