Plex is usually the most recommended media streaming and cataloging app for NAS and general servers. It's a powerful tool that has expanded over recent years into the streaming game with advertisements and all sorts of shenanigans. Jellyfin and other open-source alternatives have been on the radar for some time, but I've never felt like making the switch. It's the trouble with growing comfortable with software you've enjoyed for nearly a decade. But the time has come to move and Jellyfin will now be streaming all our purchased media from the family Synology NAS.
