PeerDrop — P2P File Transfer & Voice for VS Code

Right-click P2P file transfer combined with integrated voice calls. Zero accounts, no third-party apps. True peer-to-peer via WebRTC.

PeerDrop fills a genuine gap in the VS Code ecosystem: no existing extension combines seamless file sending with voice communication in a lightweight, privacy-first package.

Features

Right-click file transfer: Select files in the explorer, right-click, and send directly to a connected peer
Integrated voice calls: Start voice calls with your peer without leaving VS Code
Zero accounts required: No Microsoft, GitHub, or any other account needed
True P2P: File data and voice streams travel directly between developers via WebRTC
Privacy-first: Only a lightweight signaling server is used for initial connection — it never sees your data
Cross-platform: Works on Windows, macOS, and Linux

Quick Start

Install the PeerDrop extension
Person A: Open Command Palette → PeerDrop: Generate Room Code → share the 6-digit code
Person B: Open Command Palette → PeerDrop: Connect to Peer → enter the code
Send files: Right-click any file → Send File to Peer
Voice call: Click the microphone icon in the PeerDrop sidebar

How It Works

[VS Code A] ←→ [Signaling Server] ←→ [VS Code B]
                     ↓
              (initial handshake only)
                     ↓
[VS Code A] ←——— Direct P2P (WebRTC) ———→ [VS Code B]
              files + voice encrypted

A lightweight signaling server helps peers discover each other using 6-digit room codes
Once connected, all data flows directly between peers via WebRTC
WebRTC mandates encryption: DTLS for data, SRTP for voice
The signaling server never sees file content or voice audio

Commands

Command	Keybinding	Description
Generate Room Code	`Ctrl+Shift+D Ctrl+Shift+R`	Create a room and copy code to clipboard
Connect to Peer	`Ctrl+Shift+D Ctrl+Shift+C`	Join a room with a 6-digit code
Open PeerDrop Panel	`Ctrl+Shift+D Ctrl+Shift+L`	Focus the PeerDrop sidebar
Start Voice Call	`Ctrl+Shift+D Ctrl+Shift+V`	Begin a voice call with connected peer

Configuration

Setting	Default	Description
`peerdrop.signalingServerUrl`	`wss://...`	Signaling server WebSocket URL
`peerdrop.displayName`	OS username	Your display name
`peerdrop.autoAcceptTransfers`	`false`	Auto-accept incoming files
`peerdrop.maxFileSizeMB`	`500`	Max file size (1-10240 MB)
`peerdrop.defaultIncomingPath`	—	Default save folder for received files

Self-Hosting the Signaling Server

cd signaling-server
docker build -t peerdrop-signaling .
docker run -d -p 3001:3001 peerdrop-signaling

Then set peerdrop.signalingServerUrl to your server address.
