LLauncher is a lightweight, native Linux launcher for Arknights: Endfield. It handles game installation, updates, and launching through Proton — no Steam or Lutris required.
Download the latest release (AppImage / .deb / .rpm)
On Arch Linux (and derivatives like CachyOS, Manjaro, EndeavourOS) install from the AUR — dependencies are handled automatically:
yay -S llauncher-bin # or: paru -S llauncher-bin- One-click install & launch — download, verify, extract, and play
- Auto-updates — detects new game versions and patches seamlessly
- Proton management — download and manage DWProton versions directly from the launcher
- Multi-threaded downloads — up to 8 concurrent connections with per-worker speed limiting
- File verification — MD5 checksum validation for every downloaded file, with smart skip for already verified files
- System tray — minimize to tray, launch from tray
- In-app news — announcements and updates from the official API
- Configurable launch options — Gamemode, MangoHUD, DXVK Async, Wayland, custom env vars and arguments
- System checks — warns about missing dependencies (Proton, ntsync)
- Custom UI — glassmorphism-styled interface with no system decorations
- Linux (x86_64)
- Node.js >= 18 and npm (or yarn)
- Rust toolchain (rustup)
- System libraries for Tauri v2 — see the Tauri prerequisites
- glib-networking — its GIO TLS module is bundled into the AppImage at build time
- A Proton build (DWProton can be downloaded from within the launcher)
# Clone the repository

cd LLauncher
# Install frontend dependencies
npm install
# Run in development mode
npx tauri devnpx tauri buildRelease bundles will be created in src-tauri/target/release/bundle/:
| Format | Path |
|---|---|
| AppImage | bundle/appimage/LLauncher_0.1.0_amd64.AppImage |
| .deb | bundle/deb/LLauncher_0.1.0_amd64.deb |
| .rpm | bundle/rpm/LLauncher-0.1.0-1.x86_64.rpm |
Settings are stored in ~/.config/llauncher/settings.json and can be edited through the in-app settings panel.
| Category | Options |
|---|---|
| Paths | Game directory, download directory, Proton directory |
| Proton | Manage installed versions, download DWProton, system check results |
| Launch | Gamemode, MangoHUD, Vulkan, Wayland, DXVK Async, on-launch action |
| Downloads | Speed limit, concurrent connections, custom env vars, launch args |
Default paths:
Game: ~/Games/ArknightsEndfield
Proton: ~/.local/share/llauncher/proton
Config: ~/.config/llauncher/settings.json
Logs: ~/.config/llauncher/launch.log
Black screen / blank window on launch (AppImage)
Recent AppImages bundle the GIO TLS module and disable the WebKit DMA-BUF renderer automatically. If you still hit a black screen (or are on an older release):
# Install glib-networking (Arch/CachyOS: pacman -S glib-networking)
GIO_MODULE_DIR=/usr/lib/gio/modules WEBKIT_DISABLE_COMPOSITING_MODE=1 ./LLauncher_*.AppImagelibayatana-appindicator is deprecated warning
Harmless — it comes from the system tray library and does not affect functionality.
Game on an NTFS partition
The Proton prefix is stored under ~/.local/share/llauncher/prefix/ (configurable via proton_prefix_dir in settings), so the game itself may live on NTFS. Note that running games from NTFS under Linux is generally discouraged — ext4/btrfs/ZFS are safer choices.
