LAN Shuttle Pro

LAN Shuttle Pro is a blazing-fast, cross-platform local network file sharing tool. Built with a highly optimized C++ backend and a hardware-accelerated Qt Quick/QML frontend, it allows you to securely send files across your home or office network without needing an internet connection.

Inspired by apps like LocalSend and AirDrop, but engineered for maximum speed and minimal CPU overhead.

Current Features

• Blazing Fast Transfers: Uses raw asynchronous TCP sockets for maximum bandwidth utilization.
• Zero-Config Discovery: Automatically finds other devices on your Wi-Fi using UDP broadcast.
• Web & QR Code Share: Built-in lightweight HTTP server! Generate a QR code to share files instantly with iPhones, Androids, or Smart TVs—no app installation required on the receiving device.
• Modern, Fluid UI: Hardware-accelerated Material Design interface running at a smooth 60fps.
• Native OS Integration: Uses your native OS file dialogs to pick files and securely ask where you want to save incoming transfers.
• Cross-Platform: Write once, run anywhere (Linux, macOS, Windows).

Roadmap & Future Features

Coming Soon: True End-to-End Encryption (TLS 1.3)

(Expected Release: 08.2026)

Right now, LAN Shuttle Pro relies on the inherent security of your private home Wi-Fi (WPA2/WPA3). However, we are actively developing True E2E Encryption for safe use on public networks (cafes, airports).

Upcoming Security Upgrades:

• On-the-fly Certificate Generation: The app will automatically generate ephemeral RSA private keys and self-signed certificates upon launch.
• TLS 1.3 Socket Wrapping: All transfers will be upgraded from QTcpSocket to QSslSocket.
• PIN-based Pairing: 6-digit PIN verification to prevent Man-in-the-Middle (MITM) attacks.
• Certificate Pinning: The app will remember "Trusted Devices" for seamless future connections.

Tech Stack

• Core Logic & Networking: Modern C++17
• UI Framework: Qt 6 (QML & Qt Quick)
• Build System: CMake
• Architecture: Asynchronous Event-Driven (No blocking threads, zero UI freezing)

Building from Source

Prerequisites (Debian/Ubuntu)

Make sure you have Qt6, QML modules, and a modern C++ compiler installed:

sudo apt update
sudo apt install build-essential cmake \
    qt6-base-dev qt6-declarative-dev \
    qml6-module-qtquick-controls qml6-module-qtquick-layouts qml6-module-qtquick-dialogs

(For macOS/Windows, we recommend using the Qt Online Installer)

Compilation

Clone the repository and compile using CMake:

git clone https://github.com/tiwut/LAN-File-Shuttle.git
cd LAN-File-Shuttle
mkdir build && cd build

# Generate build files
cmake ..

# Compile using all CPU cores
make -j$(nproc)

# Run the app!
./appLANShuttlePro
