XIVLauncher.Core

Cross-platform version of XIVLauncher, optimized for Steam Deck

Project mention: Steam: Windows 7 and 8/8.1 will be "End of Life" on January 1st 2024 for Steam | /r/ffxiv | 2023-04-27

For FFXIV specifically, you can use XIVLauncher.Core to manage the game, which was developed specifically for the Steam Deck, but works perfectly well on Linux distros. It has the option to use the Dalamud mod API, but you can (and probably should) disable it.
