Terminal Mode provides a complete terminal experience using xterm.js, the same technology powering VS Code’s integrated terminal.

​
Features

  • Full ANSI color support - See Claude’s colorized output exactly as intended
  • WebGL acceleration - Smooth rendering even with heavy output
  • Clickable links - URLs in terminal output are clickable
  • 10,000 line scrollback - Scroll back through session history
  • Automatic resize - Terminal adapts to window and orientation changes

​
Using Terminal Mode

Terminal Mode works just like a native terminal:
  • Type commands and messages directly
  • Use arrow keys to navigate command history
  • Scroll to view previous output
  • Copy text by selecting it (browser copy)
On mobile, tap the terminal to bring up your device keyboard. Use the virtual keyboard for special keys like Ctrl+C and arrow keys.

​
Keyboard Shortcuts

All standard terminal shortcuts work:
ShortcutAction
Ctrl+CInterrupt current operation
Ctrl+DSend EOF (end of input)
Ctrl+ZSuspend process
Ctrl+LClear screen
Ctrl+AMove cursor to start of line
Ctrl+EMove cursor to end of line
↑ / ↓Navigate command history
TabAutocomplete

​
Connection Status

The status bar at the bottom shows connection state:
  • Connected (green) - Active WebSocket connection
  • Connecting (amber, pulsing) - Establishing connection
  • Disconnected (red) - Connection lost
If disconnected, the terminal displays the reason:
  • “Connection replaced by another client” - You connected from another browser/tab
  • “Connection timeout” - No data received for 75 seconds
  • “Process exited with code X” - Claude Code process ended

​
Switching to Chat Mode

Tap the chat icon in the header to switch to Chat Mode. Both modes connect to the same session - switching doesn’t interrupt your work.

​
Visual Theme

Terminal Mode uses a dark theme optimized for readability: 
Background:  #0a0a0f (near black)
Foreground:  #e8e8f0 (soft white)
Cursor:      #00ff88 (green)
The color palette supports full ANSI 256 colors for syntax highlighting and styled output.

​
Performance

Terminal Mode is optimized for performance:
  • WebGL rendering - GPU-accelerated when available, falls back to canvas
  • Efficient updates - Only redraws changed regions
  • Scrollback limit - 10,000 lines prevents memory issues
  • Binary protocol - Raw PTY data for minimal latency

​
Troubleshooting

Terminal appears blank Wait a few seconds for the connection to establish. If it stays blank, check the status bar for connection errors. Input not working Tap/click the terminal to ensure it has focus. On mobile, this should bring up the keyboard. Garbled output Try refreshing the page. Some terminal applications may not render correctly if you connected mid-output. Slow or laggy WebGL may not be available. Check browser console for WebGL errors. Try a different browser or device.
