Drop is a modern, cross-platform file sharing solution that works seamlessly across any device with a web browser. Inspired by Apple's AirDrop, it eliminates the limitations of platform-specific file sharing by leveraging web technologies for universal compatibility.

• 🌐 Universal Compatibility - Works on any device with a browser (Windows, macOS, Linux, iOS, Android)
• 🔒 End-to-End Encrypted - Secure peer-to-peer file transfers
• 🚀 No File Size Limits - Transfer files of any size
• 📱 No App Installation Required - Pure web-based solution
• 🎯 Simple Share Codes - Easy 6-character codes for quick sharing
• ⚡ Real-time Progress - Live transfer progress with visual feedback
• 🔗 Direct P2P Transfer - Files transfer directly between devices
• 🎨 Beautiful Modern UI - Intuitive interface with smooth animations

• WebRTC Signaling Server - Facilitates peer-to-peer connections
• Session Management - Handles share codes and connection coordination
• CORS Support - Enables cross-origin requests from frontend
• High Performance - Rust-powered backend for reliability

• React-based UI - Modern, responsive interface
• WebRTC Client - Handles peer-to-peer file transfers
• Real-time Updates - Live connection status and transfer progress
• File Management - Drag & drop, file selection, and download handling

1. Sender creates a session and gets a 6-character share code
2. Receiver enters the code to join the session
3. WebRTC Connection established through signaling server
4. Direct P2P Transfer - Files transfer directly between devices
5. Automatic Download - Received files are automatically downloadable

• Rust (1.80+)
• Node.js (18+)
• Modern web browser with WebRTC support

1. Clone the repository

   git clone <your-repo-url>
   cd drop

2. Start the backend server

   cargo run

   Backend will start at http://127.0.0.1:8080

3. Start the frontend (in a new terminal)

   cd frontend
   npm install
   npm run dev

   Frontend will start at http://localhost:3000

1. Open http://localhost:3000 in your browser
2. Drag & drop files or click "browse" to select files
3. Click "Create Share Link" to generate a 6-character code
4. Share the code with the recipient

1. Open http://localhost:3000 in any browser
2. Enter the 6-character share code
3. Click "Join" to connect
4. Files will be received automatically and available for download
