🚀 LLauncher

A native Linux launcher for Arknights: Endfield

Built with Tauri v2, React, and Rust

---

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: https://github.com/AugustLigh/LLauncher/releases/tag/LLauncher

Features

• 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 (7z, Proton, ntsync)
• Custom UI — glassmorphism-styled interface with no system decorations

Prerequisites

• Linux (x86_64)
• Node.js >= 18 and npm (or yarn)
• Rust toolchain (rustup)
• System libraries for Tauri v2 — see the Tauri prerequisites
• 7z (p7zip-full) — required for game extraction
• A Proton build (DWProton can be downloaded from within the launcher)
