A peer-to-peer and open-source alternative to Live Share.

This VS Code extension enables real-time collaborative editing, and...

• Remote Language Service
• Terminal Sharing
• Port Forwarding
• Chat with Images
• Text Selection Sync
• Workspace Files Sync

To start sharing, install the extension, then click Share in the P2P Live Share panel on the activity bar. No account or sign-in required. Beyond trystero's public signaling servers, you can self-host a relay server for better security and connectivity.

Connectivity

Secure Peer-to-Peer Connections

Powered by trystero, P2P Live Share establishes direct connections between peers using WebRTC. You can choose "trystero:mqtt" (preferred) or "trystero:nostr" when sharing to leverage the public signaling servers. Your data is encrypted end-to-end with the invitation link.

Self-Hosted Relay Server

Besides Peer-to-Peer connections, you can also self-host a WebSocket relay server to improve connectivity.

bunx p2p-live-share-ws-server@latest
# Supports --port and --hostname options

Or you can run the pre-built binary ws-server.

Direct Host

The host can directly listen for incoming WebSocket connections without a relay server. This is useful when the guests can directly connect to the host. You can enable this by choosing "Host Locally" and selecting a network interface when sharing.

Tencent Cloud Serverless

对于中国用户，若需自行部署，目前作者找到的较好方案是腾讯云的 Serverless 云函数：

• 新用户前三个月免费
• 假设每月调用 30 次，每次 60 分钟，流量共 300M，则费用约为 1 元
• 实测单程延迟（client -> host）约为 35ms

部署步骤：

1. 打开腾讯云 Serverless 云函数（不是 Serverless Container）

2. 新建函数，选择以下配置：

   • 创建方式：从头开始
   • 函数类型：Web函数
   • 运行环境：Go 1
   • 函数代码：选择“本地上传 zip 包”，上传 serverless.zip
   • 高级配置：
     • 内存：64MB
     • 请求多并发：自定义静态并发，设置为 100
     • WebSocket 支持：启用，空闲时间设置为 120 秒
   • 函数 URL 配置：开启公网访问

3. 部署完成后，进入“函数 URL”栏目，复制公网访问的 wss:// 地址。在 VS Code 中点击 Share 后，填入该地址即可。
