For those looking for alternatives, I would only suggest Plex if you’re OK with hitching your wagon to a different company with interests possibly competing with your own. Its great software and easy to set up but they can remove features you like and use at any time. It may be a risk worth taking for you but go into it with eyes open. I dropped them when they removed photo sync and started getting more aggressive about their content offerings.

Jellyfin is my current home and I like it a lot but I recognize that not everyone wants to deal with the setup and troubleshooting.

For some middle ground, there’s also Emby which is a commercial version of Jellyfin.
