What is Wine Cellar?

Wine Cellar is a Decky plugin that makes it super easy to download and manage different versions of Proton—without switching to desktop mode.

Alternative Tools: Wine Cellar is one of several options for managing Proton versions. Other popular tools include ProtonUp-Qt (desktop app from Discover Store) and ProtonPlus. Wine Cellar is our preferred way to manage Proton versions since it works directly in Game Mode via the Decky interface.

When Should I Use a Different Proton Version?

If you launch a game and it:

  • Shows a black screen, then closes back to the game page
  • Doesn't start at all

Then you probably need to switch your Proton version.

To find the best version for your game:
