A cool extention were you can invite your coder friends to your project to code with them together this is the local varient so everything is being hosted on your pc
Installation
Launch VS Code Quick Open (Ctrl+P), paste the following command, and press enter.
Code together in real time. Host your project from your own PC and invite friends to join — no account required.
Features
Real-time editing — everyone's changes appear instantly across all connected clients
Cursor indicators — see exactly where each participant is, with a floating name tag above their cursor line (like Roblox Studio)
Session panel — a dedicated sidebar panel shows who is in the session, which file they are in, and which line they are on. Click a name to jump straight to them
Host controls — right-click any participant to kick them, or use the inline ✕ button
Auto-reconnect — if VS Code reloads the extension host (e.g. after trusting a workspace folder), the client reconnects automatically
Clean disconnect — when a client leaves or gets kicked, the shared folder is immediately removed from their workspace and deleted from disk
Works over LAN or internet — uses localtunnel to create a public URL automatically, or falls back to a LAN ws:// address

Requirements
VS Code 1.120.0 or newer
Internet connection (for the localtunnel public URL) or both machines on the same local network (LAN fallback)
Node.js is not required by users — only needed if building from source
How it works
The host starts a local WebSocket server on a random port (30000–34999)
localtunnel creates a public HTTPS/WSS URL tunnelled to that port
Clients connect via WebSocket, receive a full file sync, and then send/receive diffs in real time
Cursor positions are broadcast to all participants and rendered as decorations in the editor
Everything runs on your own machine — no cloud backend, no accounts
Known Limitations
Binary files are skipped during sync (only UTF-8 text files are shared)
node_modules, out, and hidden folders (.git etc.) are excluded from sync
The localtunnel service is a free third-party service and may occasionally be slow or unavailable; the extension falls back to a LAN URL automatically
