macOS terminal replacement

open sourceupdated Apr 21, 2026

Feature-rich terminal emulator for macOS that has been the de facto standard for Mac power users and developers for over a decade. Supports split panes, tabs, profiles, triggers, hotkey windows, search with regex, shell integration for marks and navigation, tmux integration, and extensive customization via JSON profiles. Built-in password manager, automatic profile switching based on context, and Python scripting API for automation. Free and open-source with a loyal community.

iTerm2 is the most popular terminal emulator replacement for macOS, offering a dramatically enhanced command-line experience over the built-in Terminal.app. It provides deep shell integration that tracks commands, directories, hostnames, and usernames, enabling advanced features like click-to-download files via SCP, drag-and-drop uploads, and per-host command history. iTerm2 has been the gold standard for macOS terminal emulators for over a decade, continuously evolving to meet developer needs.

iTerm2 distinguishes itself with a comprehensive feature set including split panes in any arrangement, tmux integration that replaces tmux's text-based UI with native windows and tabs, Instant Replay for scrubbing backward through terminal history, and a built-in AI chat window for context-aware help. It supports triggers that fire actions on regex pattern matches, Copy Mode with Vim-like keyboard navigation, profiles for different environments, and a Toolbelt panel showing running jobs and command history. The terminal also includes a built-in web browser and autocomplete functionality.

iTerm2 is the go-to terminal for macOS developers, system administrators, and DevOps engineers who need a powerful, customizable terminal experience. It integrates well with popular tools like tmux, Zsh, and various shell frameworks, and supports features like Growl notifications, window transparency, and full-screen mode. As a free and open-source project with an active community, iTerm2 remains the benchmark against which other macOS terminal emulators are measured.
