From the overview:
Coax turns your home media server into a linear cable channel guide. It scans your library, then automatically generates a schedule full of channels that you can flip through at your leisure.
Point the app at your Plex, Jellyfin, or Emby server and it generates a channel guide based on genres, playlists, collections, and more. It will even display over-the-air channels if you’ve configured a compatible TV tuner — with Plex DVR, for example.
It’s an excellent app and has earned its spot next to Plex in my Apple TV’s top row.
