Faugus Launcher — AppImage

Unofficial AppImage build of Faugus Launcher, a lightweight GTK3 GUI for running Windows games on Linux via UMU-Launcher and Proton.

This repository provides only the AppImage build scripts and releases.
All application code belongs to the original project by Faugus (MIT License).

Download

Grab the latest AppImage from the Releases page.

chmod +x faugus-launcher-*-x86_64.AppImage
./faugus-launcher-*-x86_64.AppImage

Requirements

Install these two packages on the target system — everything else is bundled inside the AppImage.

Fedora / Bazzite / Aurora / Nobara

sudo dnf install python3-gobject SDL2

Ubuntu / Debian

sudo apt install python3-gi libsdl2-2.0-0

Arch / CachyOS / Manjaro

sudo pacman -S python-gobject sdl2

Why? python3-gobject provides the GTK3 Python bindings (gi), which cannot be bundled portably. SDL2 is required by the bundled pygame for gamepad support.
