Decky Loader’s official store is packed with useful add-ons, but some of the best Steam Deck plugins never make it in. This Steam Deck guide walks through ten unofficial Decky Loader plugins we have hand-picked on our plugins page, counted down to our own Decky MultiFrameGen at number one.
None of these have been through the official Decky store review, so you install them yourself. Only add what you are comfortable with.
Steam Deck guide: installing add-ons from outside the store
To install them, turn on Developer Mode in Decky’s settings, then use Install Plugin from URL or from a ZIP. If you would rather not hunt down each address, grab Decky Direct Updater later on this list. It can install and update them from GitHub, and nothing goes on your device without your confirmation.
Two things to know before you start. Xone Xbox Controller Drivers needs root, because it installs kernel drivers. Steamcord is an unofficial Discord client and may break Discord’s Terms of Service, so use it at your own risk.
TitleDeck: rename games in Gaming Mode
TitleDeck lets you rename games and rewrite their Game Info descriptions right in Gaming Mode, for both Steam games and non-Steam shortcuts. If a shortcut shows up with a messy name, or you just want your library to feel a bit more personal, you can sort it from the Deck itself. Changes stay local and can be undone, and your game files are never touched.
ResonaDeck: Plex and Jellyfin from the Quick Access Menu
If you have your own Plex or Jellyfin server, ResonaDeck plays your music, audiobooks and podcasts from the Quick Access Menu while you game. There is a controller-friendly player for quick changes, plus a bigger full manager for browsing, search and queues. It is a neat way to keep your own music library with you without ever leaving the game.
EnhancedGV: the Steam store page on your library page
EnhancedGV puts a game’s Steam store page right on its library page, below the Play button, so it never gets in the way. You get trailers, screenshots, reviews, Steam Deck compatibility and update history, all without opening the store. It can match non-Steam games to their store pages too, which makes those shortcuts feel a lot more at home.
Xone Xbox Controller Drivers: pair from Gaming Mode
The Xone Xbox Controller Drivers plugin installs the xone and xpad-noone drivers so Xbox One and Series controllers and the wireless dongle work properly, and you can pair them right from Gaming Mode. It even tells you when a SteamOS update means the drivers need reinstalling. Just know that it installs kernel drivers with root access, so it is one to install with care.
Steamcord: Discord in the Quick Access Menu
Steamcord brings Discord voice chat, DMs, text chat and even screen sharing into the Quick Access Menu, so you can talk to your friends without leaving Gaming Mode or reaching for your phone. You log in by scanning a QR code. It is an unofficial Discord client, though, so use it at your own risk with your Discord account.
AnyAspectRatio: one-tap 16:10 fixes for 100+ games
AnyAspectRatio is all about getting rid of black bars. It fixes supported games so they fill the Steam Deck’s 16:10 screen, applies the fix in one tap from Game Mode, and sets the launch options for you. Over 100 games are supported, including the Resident Evil remakes, Dark Souls III and Final Fantasy VII Remake. Just do not play Dark Souls III online with the fix. We have already covered how the Decky plugin applies those 16:10 fixes in more detail.
SCopy: share clips over Wi-Fi
SCopy is another one of our own. It shares your recordings, screenshots and clips to any browser on the same Wi-Fi, whether that is a PC, a Mac or a phone, with a four-digit PIN. You can play, download or delete them, with nothing to install on the other device. It runs as a Decky plugin on the Steam Deck and Steam Machine, and on the Steam Frame too. It is still in beta, but it is already a massive time-saver.
Unifideck: other storefronts in your Steam library
Unifideck brings your Epic, GOG, Amazon, Ubisoft, Battle.net, itch.io and Xbox Cloud games into your Steam library, so you install and play them just like Steam games in Gaming Mode. It sets up Proton for you and even syncs your Epic and GOG cloud saves. If your games are spread across a pile of different launchers, this one is a must-have.
Decky Direct Updater: keep unofficial plugins current
Decky Direct Updater is the one that makes the rest of this list easy. It finds the GitHub source of each Decky plugin you have installed and checks it for new releases, so you can update everything from Gaming Mode. You can also search GitHub and install other add-ons, and nothing installs without your confirmation. If you only grab one add-on from outside the store, start with this one. We also have a full Decky Direct Updater walkthrough if you want step-by-step help.
Decky MultiFrameGen: frame gen and upscaling in one panel
At number one is our own Decky MultiFrameGen. It manages the best Decky frame generation and upscaling add-ons in one place: OptiScaler from Decky Framegen, Mako, HelixSR, and the FSR4 Injector for AMD’s FSR4. You pick which one each game uses from a single panel in the Quick Access Menu, and it sets the launch options for you. Switching a game to another backend takes the old one out, and you can even combine them, like OptiScaler with Mako. Just note that Mako’s frame generation needs Lossless Scaling installed in Steam. It works on the Steam Deck and the Steam Machine, and it is the easiest way to try different frame gen options in every game. Our Decky MultiFrameGen setup walkthrough covers the install in more depth.
Where to find them all
You will find all ten of these, plus walkthroughs for some of them and more hand-picked community add-ons, on our plugins page at gamingonsteam.com. Whether you start with Decky Direct Updater or jump straight to a specific tool, this Steam Deck guide should make it easier to look beyond the official store without losing track of what you are installing.
