What DeckCheatz is
DeckCheatz is a free, open-source Linux tool that runs Windows game trainers on SteamOS and other supported Linux systems. It registers as a Steam Play compatibility tool, allowing Steam to launch it with an assigned game. The app matches configured trainers to the game’s Proton prefix and starts the selected trainer in the background. It targets SteamOS on Steam Deck and also supports Bazzite, CachyOS, and NixOS. The project is portable and Flatpak-ready. Listed example cheats include infinite health, infinite ammo, unlocking all items, God Mode, and Super Speed x2. DeckCheatz is intended for single-player use and solo modding, and its maker asks users to keep it offline. Trainer compatibility is still being worked out without official integrations. The current app has no in-game overlay; a Decky Loader plugin and overlay controls are planned.
