Show HN: Poly Grid – A terminal grid where agents flag you when they need input (poly-grid.com)

Poly Grid has been launched as an innovative multi-terminal grid designed for macOS users, allowing them to efficiently run multiple AI coding agents in parallel. This tool supports web servers, build watchers, log tails, and can seamlessly integrate with AI models such as Claude Code and Codex. Its standout features include the ability to broadcast prompts across various panes, facilitate data piping between terminal panes, and manage interactions within the grid through a single large language model (LLM). The significance of Poly Grid lies in its potential to streamline workflows for developers and data scientists working with AI. By enabling simultaneous operation of multiple agents and enhancing user interaction through a structured grid layout, it allows for improved productivity and greater ease of management in complex coding environments. This tool reflects the growing trend of integrating AI into development processes, offering a powerful platform to harness the capabilities of AI coding agents in a more cohesive and efficient manner. With a free download and a 7-day Pro trial available, it is positioned to attract a wide range of users seeking to enhance their coding efficiency.
