Claude Code Monitor

Monitor multiple Claude Code sessions in real-time from your terminal or smartphone.

Terminal UI

Monitor sessions with keyboard navigation

Mobile Web

Control from your phone (same Wi-Fi or Tailscale)

✨ Features

| Terminal (TUI) | Mobile Web | |----------------|------------| | Real-time session monitoring | Monitor from your smartphone | | Quick tab focus with keyboard | Remote terminal focus | | Vim-style navigation | Send messages to terminal | | Simple status display | Permission prompt navigation | | | Screen capture with pinch zoom |

• 🔌 Serverless - File-based state management, no API server required
• ⚡ Easy Setup - One command ccm for automatic setup and launch
• 🔒 Secure - No external data transmission, token-based mobile auth

📋 Requirements

• macOS or Linux (X11)
• Node.js >= 18.0.0
• Claude Code installed
• Linux only: xdotool recommended for window focus and keystroke support

🚀 Quick Start

Run with npx (no install required)

npx @arismag/claude-code-monitor

Or install globally

npm install -g @arismag/claude-code-monitor
ccm

Install from source

git clone https://github.com/arismag/claude-code-monitor.git
cd claude-code-monitor
npm install
npm run build
npm install -g .
ccm

On first run, it automatically sets up hooks and launches the monitor.

Mobile Access

1. Press h to show QR code (default port: 3456)
2. Scan with your smartphone (same Wi-Fi required)

If port 3456 is in use, an available port is automatically selected.

Remote Access with Tailscale

Access from anywhere using Tailscale (secure VPN).

Prerequisites:

1. Install Tailscale on your computer and smartphone
2. Sign in with the same Tailscale account on both devices
3. Ensure Tailscale is connected (check menu bar icon)

# Start with Tailscale IP
npx @arismag/claude-code-monitor -t

# Or if installed globally
ccm -t

With -t option, the QR code URL uses your Tailscale IP (100.x.x.x), allowing access from any device in your Tailnet - even outside your local network.

Security: Tailscale uses WireGuard encryption. Communication is secure even over public networks.

📱 Mobile Web Interface

Monitor and control Claude Code sessions from your smartphone.

Features

• Real-time session status via WebSocket
• View latest Claude messages
• Focus terminal sessions remotely
• Send text messages to terminal (multi-line supported)
• Permission prompt navigation - Respond to permission dialogs remotely
  • Direction pad for arrow keys (up/down/left/right) and Enter
  • Screen capture to view terminal state
  • Pinch zoom (1x-5x) for captured screenshots
• Swipe-to-close gesture on modal

Security

Important: Your smartphone and computer must be on the same Wi-Fi network (or use Tailscale with -t option for remote access).

• Token Authentication - A unique token is generated for authentication
• Local Network Only - Not accessible from the internet
• Do not share the URL - Treat it like a password

Recommended networks:

• Home Wi-Fi
• Office/Work Wi-Fi

Warning: Avoid using on public Wi-Fi networks (cafes, airports, etc.). Other users on the same network could potentially access your monitor.

🖥️ Supported Terminals

macOS

| Terminal | Focus Support | Notes | |----------|--------------|-------| | iTerm2 | ✅ Full | TTY-based window/tab targeting | | Terminal.app | ✅ Full | TTY-based window/tab targeting | | Ghostty | ✅ Full | Title-based window targeting via Window menu |

Linux

| Terminal | Focus Support | Notes | |----------|--------------|-------| | Any X11 terminal | ✅ With xdotool | Process tree walking to find window | | Any terminal | ⚠️ Partial | TTY-based text/keystroke send, no window focus |

On Linux, install xdotool for full focus support: sudo apt install xdotool Screen capture on Linux is not yet supported.

Other terminals can use monitoring, but focus feature may be limited.

Ghostty Users

For reliable focus functionality with multiple tabs, ccm or ccm setup will prompt you to add the following setting:

// ~/.claude/settings.json
{
  "env": {
    "CLAUDE_CODE_DISABLE_TERMINAL_TITLE": "1"
  }
}

This prevents Claude Code from overwriting terminal titles, which is necessary for tab identification in Ghostty.

If you skipped this during setup and want to enable it later, add the setting manually or delete CLAUDE_CODE_MONITOR_GHOSTTY_ASKED from your settings and run ccm again.

🔧 Troubleshooting

Sessions not showing

1. Run ccm setup to verify hook configuration
2. Check ~/.claude/settings.json for hook settings
3. Restart Claude Code

Focus not working

macOS:

1. Verify you're using a supported terminal
2. Check System Preferences > Privacy & Security > Accessibility
   • Ensure your terminal app has Accessibility permission

Linux:

1. Ensure xdotool is installed: xdotool --version
2. Verify you're running an X11 session (Wayland is not yet supported)

Reset data

ccm clear

🔒 Security

Warning: Without Tailscale, this tool is designed for use on trusted private networks only.

Never use on public Wi-Fi (cafes, airports, hotels, co-working spaces, etc.) without Tailscale. Other users on the same network could potentially intercept the authentication token and gain control of your terminal sessions, including the ability to execute arbitrary commands.

• No data sent to external servers - All data stays on your machine
• Hook registration modifies ~/.claude/settings.json
• Focus feature uses AppleScript (macOS) or xdotool/TTY (Linux) for terminal control
• Mobile Web uses token authentication on local network only
• Server-side validation blocks dangerous shell commands

Secure Remote Access

For secure access from outside your local network, use the -t (Tailscale) option:

| Mode | Network | Security | |------|---------|----------| | Default | Same Wi-Fi only | Home/Office Wi-Fi recommended | | -t (Tailscale) | Anywhere in Tailnet | WireGuard encrypted, safe on any network |

With Tailscale, communication is encrypted end-to-end, making it safe to use even on public Wi-Fi (cafes, airports, etc.).

📦 Programmatic Usage

import { getSessions, focusSession } from '@arismag/claude-code-monitor';

const sessions = getSessions();
if (sessions[0]?.tty) {
  focusSession(sessions[0].tty);
}
