Poly Grid is a multi-terminal tiling grid for macOS that lets you run webservers, build watchers, logs, and AI agents (like Claude Code, Codex) side by side in one unified workspace. It replaces alt-tabbing chaos with efficient pane management, broadcast prompts, and seamless session restore, acting as a tmux alternative optimized for AI-driven workflows.
Key benefits include:
- Multi-terminal grid: Tile panes in layouts (1×1, 2×2, 3×3) with add/remove without losing context, supporting up to 9 panes in the free tier.
- Real terminal emulation: Full PTY with bash/zsh, xterm-256color, 5,000-line scrollback, and theme customization (Default/Nord).
- AI integration: Local MCP server exposes panes to Claude/Cursor for remote control, prompting, and context capture (e.g., read output, send commands).
- Broadcast & compose: Send one prompt to multiple panes, route input via the compose bar, and use focus highlighting for typing precision.
- Workspace persistence: Session restore, named presets, and multi-grid spaces (16 total) for isolated workflows (e.g., day job vs. side project).
Perfect for developers juggling multiple terminals, AI agents, and webservers who need efficient context management without manual pane switching or LLM blind spots.
