About Decky Loader
Decky Loader is open-source software that adds plugin support to the Steam Deck. Users can browse and download plugins from the Decky Plugin Store and use them from the Quick Access menu in Gaming Mode. The plugins cover areas such as visual and sound customization, game settings, device settings, emulation, and desktop app functions.
Decky Loader is intended only for the SteamOS installation on Steam Deck. HoloISO and other third-party SteamOS distributions are not officially supported and may not work. The project has no plans to support other operating systems. The project states that it does not change Steam files and works by injecting React components into the Steam UI and running scripts in the background. It also notes that some plugins may cause lag if configured poorly, and that users are responsible for the security of their devices and for configuring plugins carefully.
