FetchP2P - Secure P2P File Transfer

A privacy-focused, peer-to-peer file transfer utility built with Next.js, WebRTC, and a custom WebSocket signaling server. Files are streamed directly between browsers with zero server-side storage.

Large File Streaming (sw.js)

Unlike many web-based transfer tools, FetchP2P does not buffer files in RAM. We use a Service Worker (sw.js) to intercept incoming data chunks and stream them directly to your disk. This allows for:

• Unlimited File Sizes: Transfer 100GB+ files without crashing your browser tab.
• Low Memory Footprint: The app typically uses less than 50MB of RAM, regardless of the file size being transferred.

Getting Started

1. Install Dependencies

npm install

2. Configure Environment

Create a .env.local file:

NEXT_PUBLIC_PEER_HOST=localhost
NEXT_PUBLIC_PEER_PORT=9000
NEXT_PUBLIC_PEER_SECURE=false
NEXT_PUBLIC_PEER_PATH=/

3. Run the Signaling Server

npm run signaling

4. Run the App

npm run dev
