Key Features

Source: GitHub README

  • tmux Integration - Native iTerm2 windows/tabs replace tmux’s text-based interface. Run tmux -CC and tmux windows become real macOS windows. Sessions persist through crashes, SSH disconnects, and even app upgrades. Collaborate by having two people attach to the same session.
  • Shell Integration - Deep shell awareness that tracks commands, directories, hostnames, and usernames. Enables click-to-download files via SCP, drag-and-drop uploads, command history per host, recent directories by “frecency,” and marks at each prompt.
  • AI Chat - Built-in LLM chat window that can optionally interact with terminal contents. Link sessions to get context-aware help, run commands on your behalf, or explain output with annotations.
  • Inline Images - Display images (including animated GIFs) directly in the terminal. Use imgcat to view photos, charts, or visual output without leaving your workflow.
  • Automatic Profile Switching - Terminal appearance changes automatically based on hostname, username, directory, or running command. SSH to production? Background turns red. Different environments get different visual contexts.
  • Dedicated Hotkey Windows - System-wide hotkey summons a terminal that slides down from the top of the screen (or any edge), even over fullscreen apps. Pin it or let it auto-hide.
  • Session Restoration - Sessions run in long-lived server processes. If iTerm2 crashes or upgrades, your shells keep running. When iTerm2 restarts, it reconnects to your sessions exactly where you left off.
  • Built-in Web Browser - Browser profiles integrate web browsing into iTerm2’s window/tab/pane hierarchy. Copy mode, triggers, AI chat, and other terminal features work in browser sessions.
  • Configurable Status Bar - Per-session status bar showing git branch, CPU/memory graphs, current directory, hostname, custom interpolated strings, or Python API components.
  • Triggers - Regex patterns that fire actions when matched: highlight text, run commands, send notifications, open password manager, set marks, or invoke Python scripts.
