Manage Proton launch options easily on your Steam Deck via Decky Loader.
Decky Proton Launch provides a simple, intuitive interface to enable commonly used Proton environment variables for your Steam games. Select one or multiple options, copy the wrapper command, or configure per-game profiles directly from the plugin.
- Fix: updating the plugin no longer wipes the launch script or the variables cache — this bug could leave already-configured Proton launch options pointing at a now-missing script until manually reinstalled
- Fix: with "Global Commands" set as the default home, the back button stopped doing anything and Settings became unreachable — the navigation bar now shows up normally in that case
Your Steam library, grouped by configuration status — Ready, Wrapper only, Commands only, Not configured — with a search bar to quickly find a game.
Click on any game to open its profile and configure launch options individually. Changes apply on next game launch.
When an option is enabled, you can instantly switch its value between Enable and Disable directly from the game profile.
Set commands once from the globe icon in the top bar and they apply to every game that has the wrapper installed — no need to configure each game individually. Add your own custom variables or wrappers directly from this page.
Open any game's page to disable a specific globally-enabled command just for that game, without touching the global setting. The Active section at the top always shows everything currently enabled, including which ones come from global commands, without having to scroll through every category.
The plugin automatically detects the currently running game and shows it at the top — click it to jump directly to its settings.
The settings view lets you choose the default home tab (variable list, game manager, or global commands) and toggle the visibility of each variable category to keep only what's relevant to you.
You can also check for plugin updates, install any past release from a version picker, force-refresh the variable data, or reset your custom wrappers/commands from here.
When a new version is available, a banner appears at the top with a direct link to download it. Past updates are also viewable at any time from the update history section.
