What is Decky Loader?

Decky Loader is a popular plugin loader for the Steam Deck. It gives you easy access to a wide range of plugins you can download and install on your Steam Deck to enhance its functionality and improve your gaming experience.

Installing Decky Loader on your Steam Deck gives you the leverage to use plugins that can do things like:

  • change system sounds
  • stylize your menus
  • change additional system settings
  • adjust your screen saturation
  • add extra game information

If you want to see some specific examples of what you can do, that is listed underneath the installation tutorial below.

Most of the plugins in Decky Loader are cosmetic. For better frames per rate and performance, check out this guide.

Once it is installed, you can access plugins and their settings by visiting the Quick Access Menu section.

Do you need to enable developer mode to install Decky Loader?

No! Enabling developer mode is no longer a requirement to install Decky Loader on your Steam Deck. This was previously a requirement, but Valve changed how applications like Decky Loader access different features on the Deck.

Enabling developer mode was a major requirement before now and you might see other tutorial guides incorrectly listing it as a requirement.

If you are curious on how to enable developer mode on the Steam Deck, you have to head into the Settings menu and toggle the Enable Developer Mode button. Then, move into the Developer menu and also toggle the Enable CEF remote debugging button.

Once you do this, your Deck will prompt you to restart your Steam Deck to effect the changes.
