Cc-bridge is a CLI tool that enables real-time communication between two or more Claude Code sessions on the same machine using a shared JSONL file, leveraging file-tail streaming for push notifications without a daemon or network. Its interesting approach combines a simple file-based IPC mechanism with specific security measures and room-based messaging, tailored for developer workflows within Claude Code. While niche, it fills a specific gap for local multi-session coordination with moderate utility.

Target audience: backend devs, devops, ai engineers
