File Share

Transfer files between devices on the same WiFi network. No cloud, no accounts—just run the app on each device and send files directly.

How it works

1. Discovery: Each device broadcasts its presence on the local network via UDP. Other devices running the app discover each other automatically.
2. Web UI: Open the web interface in your browser to see discovered devices and send files.
3. Transfer: Files are sent directly device-to-device over your local network.

Quick start

npm install
npm start

Then open http://localhost:3847 (or the IP shown in the terminal) in your browser.

Usage

1. On Device A: Run npm start and open the URL in your browser.
2. On Device B: Connect on the same WiFi and open the URL.
3. Both devices will appear in each other's "Devices on your network" list.
4. Select a device, choose files (drag & drop or browse), and click Send.

Requirements

• Both devices must be on the same WiFi network
• Node.js 18+
