I’m not your down vote, but fuck Plex. Resource-intensive code to start, and also fuck their pushy cloud-first posture. I dropped them like a hot potato when they obfuscated requiring a cloud account to watch streaming locally. Shady stuff, especially when you’re self-hosting.
Jellyfin is WAY less intrusive. It just works for local streaming, and for discreet sharing among trusted affiliates. Maybe not as pooshed or feature complete as Plex, bit it’s far less obnoxious on my resources, and my affiliates
