I used Plex for my home media for almost a year, then it stopped playing nice for reasons I gave up on diagnosing. While looking at alternatives, I found Jellyfin which is much more responsive, IMO, and the UI is much nicer as well.
It gets relegated to playing Fraggle Rock and Bluey on repeat for my kiddo these days, but I am absolutely in love with the software.
What are some other FOSS gems that are a better experience UX/UI-wise than their proprietary counterparts?
EDIT: Autocorrect turned something into "smaller" instead of what I meant it to be when I wrote this post, and I can't remember what I meant for it to say so it got axed instead.
One thing I do when adding ppl to my plex is just tell them I'm going to setup their account and hand it over for them to change the password.
Open incognito window, create plex account with their email, paste invite link from my account into the incognito window, fix their account settings, then hand it over.
Obviously a bit of a clumsy solution compared to jellyfin, but maybe that can help.
