drpl.co uses WebRTC (with WebSocket fallback) to establish direct connections between devices on the same network. When you open drpl.co in your browser, the server assigns you a unique identifier and a friendly display name. Other devices on your network running drpl.co will automatically appear, allowing direct file transfers.
- Server Component: Lightweight Node.js server provides signaling to establish peer connections
- WebRTC Data Channels: Used for peer-to-peer data transfer when supported by the browser
- WebSocket Fallback: Ensures compatibility with all browsers
- Progressive Web App: Can be installed on mobile devices
- Responsive Design: Adapts to all screen sizes
- Local Discovery: Devices find each other through the signaling server
drpl.co is designed with privacy as a core principle:
- Files transfer directly between devices, never passing through our servers
- No analytics or tracking scripts
- No data collection
- No accounts or login requirements
- All code is open source and can be self-hosted
- Open https://drpl.co on two or more devices connected to the same network
- You'll see other devices appear automatically in the interface
- Click on a device to connect and choose to send files or messages
- Select files or type your message
- The recipient will receive a notification and can download the files or view messages
To run drpl.co locally:
-
Clone the repository:
git clone https://github.com/MohdYahyaMahmodi/drpl.co.git cd drpl.co -
Install dependencies:
npm install
-
Start the server:
node server.js
-
Open
http://localhost:3002in your browser -
For local testing with multiple devices, make sure they can reach your development machine via your local IP address (e.g.,
http://192.168.1.100:3002)
drpl.co can be easily self-hosted on your own server:
- Clone the repository to your server
- Install dependencies with
npm install - Configure your web server (nginx, Apache, etc.) to proxy requests to the Node.js application
- Start the server with PM2 or a similar process manager:
pm2 start server.js --name drpl
For a production environment, it's recommended to set up HTTPS:
- Obtain SSL certificates (e.g., using Let's Encrypt)
- Configure your web server to use these certificates
- Set up a reverse proxy to your Node.js application
Example nginx configuration:
server {
listen 443 ssl;
server_name your-domain.com;
ssl_certificate /path/to/fullchain.pem;
ssl_certificate_key /path/to/privkey.pem;
location / {
proxy_pass http://localhost:3002;
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection 'upgrade';
proxy_set_header Host $host;
proxy_cache_bypass $http_upgrade;

The signaling server (server.js) facilitates the discovery of peers on the local network. Key components:
- WebSocket server for real-time communication
- Room management based on IP addresses
- Peer tracking and event propagation
- Keep-alive mechanism to maintain connections
The network.js file implements the WebRTC peer connections:
- ICE candidate exchange
- SDP offer/answer exchange
- Data channel establishment
- Chunked file transfer with progress tracking
- Fallback to WebSocket when WebRTC is unavailable
The ui.js file manages the interface and user experience:
- Device discovery and representation
- Dialog management for file transfers
- File carousel for viewing received files
- Progress indicators during transfers
- Theme switching and responsive design
drpl.co works on all modern browsers, including:
- Chrome / Edge / Brave (desktop and mobile)
- Firefox (desktop and mobile)
- Safari (desktop and mobile)
- Opera
