How to install Decky Loader on Steam Deck: Access Epic Games, Battle.net, Ubisoft Connect, and more game launchers

Diablo 4 on Steam Deck.

The Steam Deck is a pretty awesome gaming handheld, but the fact that it cannot easily access game services out of the box other than Steam can make it feel a bit limiting. Thankfully, there's a helpful homebrew plugin called Decky Loader that widens the gaming handheld's initial abilities. With it installed, you can easily access your library of games on Epic Games, Ubisoft Connect, and more. 

Plus, Decky Loader comes with a bunch of cool widgets and additional settings that you can install as desired. Here's how to get Decky Loader installed and enable its various features.

1. Turn on Developer Mode

To start things off, we need to make sure that the Steam Deck has Developer Mode enabled. Here's how to do that. 

  1. Press the Steam button
  2. Select Settings
  3. Select System
  4. Make sure Enable Developer Mode is toggled on (to the right)
  5. In the left menu, scroll down and select Developer
  6. Scroll down to the Miscellaneous section and toggle on CEF Remote Debugging.
  7. Press the Steam button again. 
  8. Select Power.
  9. Select Restart and then Confirm.

2. Download Decky Loader in Desktop mode

With Developer Mode on and the handheld restarted, it's time to head to the Steam Deck's Desktop mode for the next stage of the Decky Loader install process.

  1. Press the Steam button.
  2. Select Power.
  3. Select Switch to Desktop Mode
  4. You need to use Google Chrome for this to work. If you don't have it installed yet, open a browser (Mozilla Firefox is in the bottom tray by default). Press Steam button + X to bring up (or close) the on-screen keyboard and type in "Google Chrome download" into the search bar. Then, download/install the Debian/Ubuntu version of the app. 
  5. Using Google Chrome go to the Decky Loader download page on GitHub.
  6. Click the big Download button. 
  7. After the app has downloaded, close out of Chrome and open the Dolphin file explorer (the blue file icon on the bottom tray). 
  8. Click on Downloads and then drag and drop the Install Decky file onto the desktop
  9. Double-click on Install Decky and run through the recommended installation settings. If your Deck is set to Beta Steam OS, choose the prelease option; otherwise, choose release. Then click OK.
  10. After installation has completed, click OK
  11. Click on the Return to Game Mode icon on the desktop.

3. Activate Decky Loader's NonSteamLaunchers app

At this point, Decky Loader is on Steam Deck, but you haven't yet made it possible to access various game launchers. Here's what you need to do to install these. 

  1. Press the three-dot button on the right of the Steam Deck. This is the Quick Access Menu button (QAM).
  2. Go to the outlet Plugin tab at the bottom and click on the small cogwheel Settings button. 
  3. Change the Store Channel drop-down menu to Testing
  4. Press the QAM button again and select the Store button next to settings. 
  5. Scroll down and install the NonSteamLaunchers app
  6. Press Install again. 
  7. Press the QAM button and select the newly added NonSteamLaunchers app.
  8. Select Game Launchers
  9. Toggle on the game launcher you want to use. 
  10. Scroll down and toggle on Separate Launcher Folders
  11. Next select Install. Wait while installation completes.
  12. When done, press the Steam button
  13. Go to Library
  14. Use R1 to switch to the Non-Steam apps and select the launcher you just added. 
  15. Select Play to open the game launcher app.

Our Top Gaming Recommendations

Take some time to explore within Decky Loader to see all of the plugins and widgets it provides you with. You might find you like some of the new settings provided. 

Remember that you will still need to log in to whatever game launcher services you access through Decky Loader, so be ready to enter your account information before you can start playing your different game libraries. 

Controller support isn't always guaranteed to work on some of these services. As such, you might need to connect a keyboard and mouse to play certain games or try to find other solutions to play on Steam Deck.
