iTerm2

iTerm2 is a terminal emulator for macOS, developed by George Nachman as the successor to iTerm and a modern replacement for the built-in macOS Terminal application. The software requires macOS 12.4 Catalina or later and is distributed as free open-source software under the GPL v2 license with the source code available on GitHub at gnachman/iTerm2. iTerm2 has become the de facto standard terminal for macOS developers, offering features that include split panes for viewing multiple sessions side by side in a single window with horizontal and vertical splits, hotkey windows that can be summoned from any application with a configurable global keyboard shortcut for quick terminal access, search across the entire scrollback buffer with regular expression support, and a built-in profile system for managing different terminal configurations with custom colors, fonts, key mappings, and startup commands. The terminal supports trigger-based automation where incoming text matching patterns can execute scripts, highlight text, or send notifications, and includes a Python API for programmatic control of windows, tabs, panes, sessions, and profiles. Additional capabilities include inline image display with the imgcat utility, 24-bit color support, semantic history for opening files at specific lines from the terminal in any editor, copy mode with vim-like keybindings, badge overlays showing dynamic information, password manager integration, shell integration for marking command boundaries, and pointer reporting for mouse-aware applications. The community provides support through Google Groups, GitHub issue tracker, and direct email.
