SyncVibe

SyncVibe is a multiplayer chat room for AI coding agents, letting several people work together while each uses their own AI. A user opens a room, shares a short invite code, and everyone in the room can mention each other's agents, whether Claude, Codex or Gemini, directly in the chat. The design is local first. A relay forwards chat messages over WebSocket, but every AI runs on its owner's machine through MCP, using the owner's credentials and checkout. A friend's agent can be asked to work on a file, and the output streams back to everyone in the room. When a room has a repository, it clones automatically on a joining member's machine. Nothing lives server side, and repositories and API keys stay on each person's laptop. The vendor suggests building a side project with a friend, pair debugging without sharing a keyboard, teaching someone to use an agent while they run it in their own environment, and running a live code review where the reviewer suggests prompts and the author's agent executes them. Installation is through Homebrew on macOS and Linux, and the source is on GitHub. SyncVibe is described as free and open source, and the site lists no paid plans.
