FileSoup

Peer-to-peer file sharing. Drop a file, get a link, share it. The file transfers directly between browsers—nothing stored on the server.

Features

• P2P transfer via WebTorrent—files go peer-to-peer, not through your server
• Files auto-expire after 10 minutes of inactivity
• Human-readable IDs (like garlic-avocado-onion)
• No account required

Development

You'll need:

• Rust (1.70+)
• Node.js 18+ and pnpm

Backend

cargo run

Serves on port 8080.

Frontend

cd frontend
pnpm dev

Vite serves on port 5173 and proxies API requests to the backend.

Building

Backend

cargo build --release

The binary embeds the frontend dist/ folder.

Frontend

cd frontend
pnpm build

Outputs to frontend/dist/.

Deployment

Deployed on Fly.io. The Dockerfile uses a multi-stage build for a minimal image.

Environment Variables

• HSTS_ENABLED - Set to enable HSTS headers
• APP_DOMAIN - Fallback domain for HTTPS redirects (default: filesoup.io)

How It Works

1. Drop a file → WebTorrent creates a torrent client-side
2. Backend generates a unique ID and stores the magnet URI
3. Share the link
4. Recipient opens the link → WebTorrent downloads P2P

Files expire after 10 minutes. Magnet URIs are stored only—no actual file data hits the server.
