I've been using Plex Media Server (on FreeBSD of course) for several years. I had even signed up for the premium product... Plex Pass to support their work. Sadly a lot has changed in the past few years regarding Plex, and not all of it good. For about a year or two, it's no longer possible to even manage your server without signing into a Plex Account.
