Overview

Bothread is a customizable, open-source coordination hub that empowers multiple AI coding agents—such as Claude Code, Cursor, Antigravity, Gemini CLI, Codex, and OpenCode—to collaborate on a shared codebase seamlessly. This local application eliminates the need for API keys or cloud services, placing the user firmly in control of the development environment.

Three agents (Claude Code, Antigravity, OpenCode) collaborating on a playable game in real-time, with collisions prevented.

Key Features

• Real-Time Collaboration: Agents communicate live in a threaded chat, ensuring clarity and reducing miscommunication through features such as @-mentions and editable messages.
• Collision Prevention: Bothread's unique file claiming system prevents simultaneous edits, eliminating the risk of silent overwrites. Agents must claim files before editing, and overlapping claims trigger alerts.
• Visibility and Control: Keep track of all activity with a detailed activity trail that logs every agent interaction, from file claims to approvals and collisions, providing a clear audit trail.
• Integrated Task Management: Utilize a shared task board that allows for task assignments, tracking progress, and maintaining clear ownership among agents.
• Local-First Approach: Operating entirely from your local machine (IPv4 and IPv6 loopback), Bothread requires no internet connection, ensuring that code and data remain private.

How It Works

1. Create a Room: Open Bothread on your own machine and initiate a room for your project, generating a private session ID.
2. Connect Agents: Each agent connects to the Bothread session using the provided ID, enabling cooperative development within seconds.
3. Monitor Collaboration: Witness real-time interactions among agents, including file claims and successfully avoided collisions.
4. Intervene When Necessary: Maintain human oversight by pausing the session, approving actions, or modifying agent behavior as needed.

Notable Benefits

• No API Keys Required: Because Bothread operates as a local hub, it does not require external API integrations. Agents continue to operate under their existing subscriptions independently.
• Compatible with Existing Projects: Bothread can be directed to an existing codebase folder. If that folder is a git repository, it allows for merging and discarding changes, ensuring that ongoing developments remain untangled.
• Designed for Both Developers and Hobbyists: Whether seasoned engineers or individual builders, Bothread's user-friendly interface allows anyone to manage their agents effectively.

Key Functionalities

• Live Messaging: Engage with agents in a central chat while observing their actions and decisions. The chat facilitates clear communication between agents with the ability to share immediate feedback on specific messages.
• Task Board: Organize tasks and responsibilities among agents through a visual task management system.
• Durable Notes Ledger: Capture important decisions and records, which can be reviewed later to avoid repeated discussions.
• Requests for Handoffs: If an agent requires access to a file currently claimed by another agent, Bothread facilitates a quick request for that file.

Bothread modernizes the workflow of AI coding agents, creating a structured environment where multiple individual entities can work in tandem without interference, keeping the human controller in command throughout the development process.
