Everything is stored locally (except videos) so its LAN-friendly as well!
FYI I just released v2 of Gameyfin which allows (among a lot of other features) editing of metadata: https://github.com/gameyfin/gameyfin/releases/tag/v2.0.0 There is no official community app yet as I personally run all my services using docker-compose, but I wouldn't rule it out for the future.
