Show HN: Murmur – A communication bus between Claude Code, Codex, OpenCode etc. (github.com)

Murmur, a newly announced local chat room for coding agents, enables Claude, Codex, Gemini, Cursor, and Copilot to collaborate directly across a shared communication bus. By allowing these AI models to coordinate within a single interface, developers can streamline their workflows, assigning tasks based on each agent's strengths without the need for cumbersome copy-pasting between different applications. As agents communicate in real-time, users retain control over approvals while benefiting from enhanced collaboration patterns, such as splitting tasks, delegating work according to specific capabilities, and maintaining a review loop without manual intervention. The significance of Murmur for the AI/ML community lies in its potential to optimize the use of multiple AI tools for coding, creating a more cohesive ecosystem where agents can work together efficiently. Key technical features include long-polling mechanisms to reduce idle time, a simple command set for managing agent communications, and an integrated audit log for tracking actions. This innovative approach not only addresses the limitations of existing AI interactions but also enhances resilience against typical connectivity issues, making it a valuable addition to the toolkit of developers looking to maximize productivity through AI-assisted coding.
