You can still use tailscale and reverse proxy to allow remote streaming

I used to use Plex and when I discovered there was paid remote streaming function - that goes through their servers - my reactions were “Haha, no”* and checking whether my existing WireGuard setup would do it instead.

Whaddya know, remote streaming using Plex and PlexAmp at no cost.

*Not because I begrudge them recouping costs, but because it’s designed that way to justify charging for it, gives them whatever information they want from my viewing, and it’s not self-hosting if there’s any third party cloud/account component to it.
