Yes. You’ll have to set up a reverse proxy, I use nginx, and get yourself domain, I use duck DNS, and get a SSL certificate from let’s encrypt if your wanting to steam to something like a Chromecast or Roku.

It’s not all that hard honestly and there’s a good guide here for general home media, including both Plex and jellyfin

If you don’t like the price there’s always jellyfin.

Got to say that I have been very happy with it.
