📱 Laptop Remote (Remote Deck)

Turn your smartphone into a powerful, low-latency remote control for your laptop. Control media playback, stream a high-precision trackpad, navigate with a virtual D-Pad and keyboard, and present with a real-time screen laser pointer.

⚠️ LAN-only tool. Designed for trusted local networks (home Wi-Fi / hotspot). Do not expose it to the public internet — see SECURITY.md.

✨ Features at a Glance

• ⚡ Terminal / Headless Edition: A lightweight, no-GUI server that prints a QR code and pairing PIN directly in the terminal.
• 🌐 Zero-Config Discovery: Connect instantly via QR code scan, local IP, or mDNS (http://remotedeck.local:5000).

🔒 Security & Connection Details

• Rolling One-Time PIN: A fresh 6-digit PIN is generated upon startup and regenerated after each successful pairing or manual revocation.
• Brute-Force Protection: IP-based lockout triggers automatically after 5 consecutive incorrect PIN attempts (30-second escalating lockout).
• Bearer Token Authorization: Paired devices receive a cryptographically secure 48-character session token stored locally on your device.
• Dual Transport: High-frequency mouse coordinates and laser pointer positions stream over WebSockets for minimal latency, with automatic fallback to REST endpoints if required.
• Offline Self-Contained: Socket.IO client library and assets are fully bundled locally — no internet connection or CDN required.

⚙️ Configuration & Custom Presets

Key mappings are defined in presets.json. You can customize or add hotkeys for your favorite applications:

{
  "youtube_hotstar": {
    "play_pause": "space",
    "skip_forward": "l",
    "skip_back": "j",
    "skip_forward_30": ["l", "l", "l"],
    "next": ["shift", "n"],
    "fullscreen": "f",
    "subtitles": "c",
    "speed_up": ["shift", "."]
  },
  "universal": {
    "play_pause": "space",
    "skip_forward": "right",
    "skip_back": "left",
    "fullscreen": "f"
  }
}

🖥️ Platform Support

Laser pointer note: Windows uses its native Tk overlay. Linux uses an X11 SHAPE 1.1 window with an empty input shape so mouse and touch events pass through. A direct Wayland session is not supported. XWayland availability depends on its display exposing SHAPE 1.1; if initialization fails, the app reports the pointer unavailable and keeps the laser pad hidden. macOS support is not yet implemented.

🧪 Running Tests

# Python backend tests (82 tests)
pip install -e ".[dev]"
pytest

# Frontend unit tests (17 Vitest tests)
npm install
npm test

Tests run automatically on Linux, Windows, and macOS via GitHub Actions.
