FileDrop — P2P File Transfer

Simple peer-to-peer file sharing over the same network, inspired by ShareDrop.
Built with plain HTML/CSS/JS + PeerJS + Vite. Deploys as a static site to Cloudflare Pages.

How it works

  • Each browser tab gets a unique ID via PeerJS (uses public STUN/TURN)
  • Share your ID with someone on the same network (or paste theirs)
  • Click their node → pick a file → send
  • Receiver gets a toast notification → accepts → file downloads automatically
  • No server stores your files — pure WebRTC P2P

Getting started

npm install
npm run dev

Open http://localhost:5173 in two tabs (or two devices on same WiFi).

Build

npm run build
# output in /dist — upload this folder anywhere static

Deploy to Cloudflare Pages

Manual drag & drop

npm run build

Go to Cloudflare Pages → Upload assets → drag the dist/ folder.

Customization

  • PeerJS server: By default uses the free public PeerJS cloud server.
    For production, self-host peerjs-server: https://github.com/peers/peerjs-server
    Then update peer.js constructor options: host, port, path.

  • Peer discovery on LAN: PeerJS uses STUN for WebRTC. For fully offline LAN-only usage,
    run your own peerjs-server on the same network and remove the public STUN config.
