System Requirements

  • Operating System: macOS
  • Xcode: 16.x or 26.x

​
Step 1: Install cmd

Install with Homebrew (Recommended)

Alternatively, download the latest release:
  1. Visit the releases page
  2. Download the DMG file
  3. Open the DMG and drag cmd to Applications
  4. Launch cmd from Applications or Launchpad
cmd will automatically update, unless auto-updates are disabled.

​
Step 2: Grant Permissions

cmd needs specific permissions to integrate with Xcode.
cmd needs accessibility permission to integrate with Xcode:
  1. Launch cmd
  2. When prompted, click “Open System Settings”
  3. Enable cmd in Privacy & Security > Accessibility
  4. Return to cmd
Without this permission, cmd cannot see your Xcode context or make edits.
cmd also needs Xcode extension permission:
  1. When prompted, click “Open System Settings”
  2. Enable cmd in Privacy & Security > Extensions > Xcode Source Editor
  3. Restart Xcode for the changes to take effect
You must restart Xcode after enabling the extension for it to work properly.

​
Step 3: Configure AI Providers

cmd requires at least one AI provider to function. You’ll configure this during the onboarding flow.
1

Choose a Provider

Select from supported providers like OpenAI, Anthropic, Google AI, or others
2

Enter API Key

Provide your API key from the chosen provider
3

Test Connection

cmd will verify your configuration works
4

Enable Models

Choose which models you want to use

Complete AI Provider Setup

See the full guide for configuring AI providers and managing API keys
Your API keys are stored securely in macOS Keychain. cmd never sends your code to its own servers—only to your chosen AI provider.

​
Step 4: Configure Xcode 26 (Optional)

If you’re using Xcode 26, you can integrate cmd with Xcode’s built-in AI chat interface.
1

Open Xcode Settings

In Xcode, go to Xcode > Settings > Intelligence
2

Add Model Provider

Click “Add a Model Provider”
3

Configure Local Model

Select a local model running on port 10101:Xcode 26 model provider setup
4

Use Either Interface

You can now interact with cmd through:
  • Xcode’s AI chat: Built into Xcode 26
  • cmd’s sidebar: The native cmd interface
Using cmd in Xcode 26
The Xcode 26 integration gives you flexibility to use whichever interface you prefer while benefiting from cmd’s powerful agentic AI.

​
Privacy & Security

Your code stays on your machine
  • cmd runs entirely locally
  • Your code is only sent to your chosen AI providers
  • You can opt out of anonymized analytics
  • API keys are stored in macOS Keychain
