Faugus 2.5.6 adds Discord Rich Presence to its Linux game launcher
Faugus Launcher, the open-source front-end that runs Windows games on Linux through Proton and UMU, just got Discord Rich Presence. Version 2.5.6 landed on GitHub today, tagged as commit 17adc90 and authored by the developer known online as "Faugus" (Felix Ribeiro). Now the game you're playing shows up on your Discord status. There's more under the hood than that one feature, though.
The release also adds automatic detection of a game's title, icon, and cover art straight from the executable. Theme and color changes now stick without forcing a restart. A batch of bug fixes, several of them credited to contributor @Yousef-Mohamed22, rounds out the update alongside some memory and performance work.
Faugus is part of a crop of "Proton-native" launchers gaining ground against heavier hitters like Lutris and Heroic Games Launcher. It markets itself with a deliberately simple pitch: "A simple and lightweight app for running Windows games using UMU-Launcher."
Built on UMU, built fast
Faugus is essentially a polished graphical skin over UMU-Launcher, the community project under the Open Wine Components umbrella. UMU makes running non-Steam Windows games through Proton roughly as smooth as running Steam games, by standardizing how launchers talk to Proton and apply per-game fixes.
The payoff is that Faugus inherits the shared, community-maintained protonfix database and launches games through Proton like they're native Steam titles. That's the technical foundation that lets it install storefront clients like Battle.net, Ubisoft Connect, and the EA App with just a few clicks.
It's a Python application (roughly 99 percent of the codebase) built on GTK 4 and libadwaita, so it leans into that GNOME-flavored look. MIT licensed, around 2,600 GitHub stars, roughly 96 forks, and Felix Ribeiro is by far its main contributor with about 1,980 commits. He started the project in mid-2024.
What's actually new
Discord Rich Presence is the headline. When you're in a game, its name shows on your status. Keep in mind that the Discord Flatpak needs an explicit filesystem permission for this to work: --filesystem=xdg-run/app/com.discordapp.Discord. Faugus flags that as a temporary workaround, for now.
Automatic title, icon, and cover detection is the other convenience. Add a game and Faugus reads embedded resources from the .exe to populate your library, which means less manual metadata entry.
Theme changes now persist through the session instead of bailing until you restart the app. Not world-changing, but it's the sort of thing that gets annoying fast when it doesn't behave.
The fixes are mostly small but real. Shortcut path quoting and launch-argument handling got corrected, along with environment-variable detection for shortcuts and file runs. There's a fix for the Lossless Scaling frame-generation check and one that stops backups from clobbering existing archives. Two more address a context-menu activation quirk on right-click release and memory leaks that accumulate when closing dialogs.
The performance moves are the more interesting part. Splash and donate windows now run as separate processes, so memory returns to the system instead of being parked for the app's whole lifetime. GTK is loaded on demand in the runner too, trimming the startup footprint. These continue a trend from 2.5.4 focused on keeping the library view smooth with large game libraries by loading artwork on demand rather than up front.
How it stacks up
Faugus has built a reputation for being far less overwhelming than Lutris, which can still feel like flying a cockpit for newcomers. The philosophy is add game, pick Proton, play. It's especially handy for storefront launchers that historically were a pain on Linux.
It isn't a complete Lutris replacement yet. Steam integration can be flaky on some setups, you still have to locate and point to game executables yourself, and if you want cloud-save sync for Epic or GOG, Heroic Games Launcher remains the go-to.
You can grab 2.5.6 from the GitHub release page in four formats. The .deb is the most popular at 44 downloads so far, with the AppImage around 14, the Fedora RPM and Arch PKGBUILD trailing near 3 or 4 each. A source tarball and a Flathub Flatpak are also available. If you're on Arch, yay -S --noconfirm faugus-launcher pulls it straight from the AUR.
