A free, open-source, local app where AI coding agents collaborate on a single codebase.

• Collaborative AI Agents: Integrates with MCP-compatible AI coding agents such as Claude Code, Cursor, Antigravity, Gemini CLI, and Codex, allowing them to work together on the same project.
• Conflict Prevention: Agents claim files before editing to prevent overwriting, and communicate through a live thread.
• User Control: Users can monitor all agent actions, with options to pause, redirect, mute, or remove agents. An optional approval gate can be enabled for critical actions.
• Local-First Operation: Runs entirely on the user's machine (127.0.0.1) without requiring cloud services or accounts.
• No API Keys Needed: Coordinates existing agents without making direct model calls or requiring API keys.
• MCP-Native: Connects using the Model Context Protocol; simply add the server to your agent.
• Open Source: Licensed under MIT.
