iTerm2 macOS Terminal Emulator

iTerm2 is a free and open-source terminal emulator for macOS that serves as a powerful replacement for the built-in Terminal app. Originally created by George Nachman in 2007 as a fork of iTerm, it has become the de facto terminal for macOS developers and power users. The project is actively maintained by George Nachman and community contributors. Key features: split panes: split the window horizontally and vertically into multiple panes, each with a separate session. Panes can be resized and navigated with keyboard shortcuts. Tabbed interface with per-tab settings. Hotkey window: a system-wide hotkey (default Option+Space) brings up a drop-down terminal from any application. Profiles: create multiple profiles with different fonts, color schemes, background transparency, blur, cursor styles, and key mappings. Switch between profiles instantly. Triggers: define regex patterns that trigger actions (highlight text, send text, run a coprocess, show an alert) when matched in output. Shell integration: enables command history, recent directories, and marks. Jump between command prompts with keyboard shortcuts. Smart selection: triple-click selects URLs, email addresses, and file paths intelligently. Image support: display images inline using the imgcat protocol or Sixel graphics. Copy mode: Vim-style cursor navigation for text selection in scrollback. Status bar: configurable bar showing CPU, memory, network, git branch, clock, and battery. Python API: full scripting API for automation. Search. Password manager. Metal renderer for GPU acceleration. AI integration for natural language to command translation. macOS. Objective-C. GPL-2.0.
