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.

Demo

Every agent pane on the Mission Map, approvals from one inbox, per-line diff comments sent straight to the agent, tab groups, and every command in the palette (30s):

Why Calyx

See which agent needs you

The Agents Sidebar shows every connected agent as working, blocked, idle, or done, and expands a pane into the subagents it is currently running. Unread badges and click-to-focus navigation replace the loop of checking terminal tabs one by one.

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 macOS-notification-style panel at the top-right of your screen: a primary action plus an Options pull-down listing every other choice the CLI offers, including its own always-allow suggestions. Click the request text to expand its full payload, or hover it to read the full text in a tooltip. A Claude Code AskUserQuestion prompt answers the same way -- pick an option from Options, or from an inline option list when the question allows several answers at once or carries a preview, choose "Other…" to type a free-text answer, add notes, or hand the conversation back to the CLI with "Chat about this" -- 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 off its tool calls run unreviewed.

Review code without leaving the terminal

Inspect working changes and commit history in the Git sidebar, add comments to individual diff lines, and submit the complete review directly to a Claude Code, Codex, OpenCode, Hermes, or Grok pane.

Give agents a terminal they can understand

Calyx exposes panes, commands, captured output, browser tabs, language servers, and peer agents through MCP and its bundled CLI. Agents can coordinate work, wait for commands to finish, and inspect results instead of relying on sleep timers or copied output.
