do you need a plex pass to view others servers or to have others view yours ?
No.
Here’s a summary of what you need to watch content from a remote server.
From https://support.plex.tv/articles/requirements-for-remote-playback-of-personal-media/
When using an affected platform to stream personal video content remotely from a Plex Media Server, then one of the following needs to be true:
- The admin account for the Plex Media Server has an active Plex Pass (which also allows remote playback for any other user streaming from that server)
- Your account has an active Plex Pass
- Your account has an active Remote Watch Pass
The remote playback restrictions do not apply to streaming music content to Plexamp or photos to our Plex Photos app.
