Grok Build Desktop

Grok Build Desktop is a local-first macOS app for working with multiple coding agents without losing the session you were in. Pick an agent when you start a session, keep several sessions running, and move between them while background turns continue.

Supported agents

Grok Build

Grok runs through the locally installed Grok CLI. Each live desktop session has its own isolated agent bridge, so one long turn does not block another session. Messages, thoughts, tools, approvals, and HQ command seeds render in the native chat interface.

Codex

Codex runs through codex app-server and uses the authentication already owned by the Codex CLI. The model menu is loaded from your installed Codex catalog rather than being frozen into the app. The reasoning menu exposes every level reported for the chosen model, including Low, Medium, High, Extra High, Max, and Ultra when supported.

Authenticate before use:

Terminal window
codex login

Claude Code

Claude opens as a real PTY-backed terminal inside the app. Authentication and credentials stay entirely inside the locally installed Claude CLI; Indigo does not proxy or store them.

When you explicitly choose Claude, the app launches:

Terminal window
claude --dangerously-skip-permissions

If Claude reports an expired or revoked token, run /login in the embedded terminal. That repairs the CLI-owned login without sending credentials through the desktop app.

Start and switch sessions

  1. Select New session.
  2. Choose Grok, Codex, or Claude in the agent picker.
  3. For Codex, choose a model and available reasoning level.
  4. Start work. You can open another session while the current agent continues.
  5. Select any sidebar row to return to its transcript or terminal.

The selected agent is locked after a session starts. Create a new session to use a different agent. This keeps provider state, history, approvals, and running processes isolated.

Claude terminal appearance

Open Settings → Appearance to choose a terminal font preset or custom font stack. Font sizes from 11–24 px are supported. The terminal also preserves ANSI color, Unicode drawing characters, resize behavior, scrollback, and CLI redraws.

Requirements

  • macOS on Apple Silicon
  • The CLI for each agent you plan to use must be installed and available on PATH
  • Each CLI must be authenticated with its own supported login flow

The app is signed, notarized, and updates through its public release feed.

Troubleshooting

  • A session will not resume: Stop and start that session. Other sessions are not stopped.
  • Codex models are missing: Update the Codex CLI, sign in again, and reopen the model picker.
  • Claude shows 401 or revoked OAuth: Run /login in the Claude terminal.
  • A CLI is not found: Confirm grok, codex, or claude works in Terminal and is on your shell PATH.
