Calyx

**Run more coding agents without babysitting more terminals.**

Calyx is a native macOS terminal for running and supervising coding agents (Claude Code, Codex, OpenCode, Hermes, Grok, and pi...) in parallel. It keeps every agent visible and controllable with one approval inbox, live status, persistent sessions, agent-readable command history, and inline diff review -- without replacing the terminal workflow you already use.

Approve tool calls from one inbox

Claude Code and Codex permission prompts, the tool calls of Grok sessions running in always-approve mode, and every pi tool call appear in a shared in-window approval queue. Inspect the exact request, allow or deny it, and move through pending requests without hunting for the pane that raised them. Enable the integration explicitly in Settings; nothing is automatically approved unless you separately opt in. pi ships no permission prompt of its own, so with the integration of
