Real-time coordination for Claude Code
Multiplayer mode
for your AI agents.
Run 3, 5, 10 Claude Code instances on the same project - without them stepping on each other. File claiming, context sharing, and conflict prevention. One plugin install, zero config.
See what every agent is doing - live
Every claim, context share, and message flows through the relay in real time. The built-in dashboard shows you the full picture at localhost:7400.
Four primitives. Zero conflicts.
Seven MCP tools enforced by a mandatory skill layer. Claude checks peers, announces tasks, claims files, works, then releases - every single time.
Agents declare intent before writing
Before editing a file, an agent claims it through the relay. Other agents see the claim instantly and pick different work. Soft-locks with 30-minute TTL - no blocking, just awareness that prevents wasted effort.
One relay. Zero binaries. Auto-discovery.
A ~300 line pure-JS WebSocket relay spawns when the first agent starts. Project ID is derived from your git remote URL - agents on the same repo find each other automatically. No config, no daemon, no NATS.
Agent instance
Each Claude session gets an MCP server with 7 coordination tools. Hooks intercept file writes automatically.
Relay
Pure Node.js pub/sub + KV store. Auto-spawns locally on :7401, or point to a shared VPS for teams.
Dashboard
React SPA at localhost:7400. Live peer grid, task list, file claims, and activity feed - all real-time via WebSocket.
How every task flows
Claude starts → MCP server connects to relay → heartbeat sent
User asks Claude to code → Claude calls sync_check_peers
Claude calls sync_claim_files → file soft-locked for 30 min
Claude writes code → PreToolUse hook verifies no conflicts
Work done → sync_complete_task → claims released, peers notified
Running in under a minute
One plugin install. Dependencies auto-install on first session via the SessionStart hook. No daemon to manage, no config files to write.
Then open multiple Claude Code instances on the same project. They find each other automatically.
Start free. Scale when you need to.
The full coordination stack is open source and free forever. Cloud tiers add hosted relay, persistent history, and team management.
