Show HN: Cc-bridge – Two Claude Code windows talking via one JSONL file (github.com)

The newly launched cc-bridge tool facilitates real-time communication between multiple Claude Code sessions on the same machine through a live JSONL message bridge. Users can execute commands like `cc-bridge listen` and `cc-bridge send` to send and receive messages instantly without the need for a daemon, network, or polling. This simple yet effective setup allows for seamless collaboration within code development environments, promoting efficiency and real-time feedback among developers. Significantly, cc-bridge enhances intra-machine communication by establishing a local Inter-Process Communication (IPC) method that maintains data integrity within the user's environment. Its design, featuring sanitized room names and strict message size limits, ensures a secure working landscape while minimizing external dependencies. With future upgrades planned for cross-machine functionality and enhanced user features, the cc-bridge aims to empower developers who utilize Claude Code, fostering an innovative space for AI/ML projects. The tool can be easily installed via npm and requires Node.js version 20 or above, making it accessible to a wide range of users in the AI/ML community.
