Show HN: Hall Monitor. See all your agents across machines on your Mac's Notch (github.com)

A new tool called Hall Monitor has been launched, designed specifically for developers using AI coding agents like Claude Code and Codex on their machines. This application allows users to monitor their agents across various devices—including laptops and GPU servers—by displaying real-time status updates in an accessible format. Users can quickly see which agents are active, idle, or require attention, with detailed insights such as the current tool, last prompt, model, and context size. Notably, Hall Monitor only reads information and does not send prompts or interact with the agents, ensuring a secure and passive monitoring experience. The significance of Hall Monitor for the AI/ML community lies in its ability to streamline workflow and enhance productivity by providing a centralized view of AI agent performance. Developers often juggle multiple sessions, and this tool alleviates confusion about the status of ongoing tasks. The installation is straightforward through Homebrew or building from source, and it supports SSH connections for remote monitoring without needing a network daemon. By eliminating the need for additional prompts or interactions and focusing solely on usage metrics, Hall Monitor serves as a lightweight solution for efficient management of AI agents, ultimately fostering a more productive development environment.
