iTerm2 is a free and open-source terminal emulator for macOS, licensed under GPL-2.0-or-later. It was derived from and has mostly supplanted the earlier "iTerm" application.
iTerm2 supports operating system features such as window transparency, full-screen mode, split panes, Exposé Tabs, Growl notifications, and standard keyboard shortcuts. Other features include customizable profiles, Instant Replay of past terminal input/output,23 a Toolbelt showing running jobs and a command history,4 the ability to open when a key combination is pressed,5 and autocomplete.6
History
A Mozilla-sponsored 2019 code audit found one serious security vulnerability in iTerm2's tmux integration, which developer George Nachman fixed in an update.7
Reception
Software engineer Mike Rourke called it an "excellent [...] more full-featured Terminal" than Apple's built-in Terminal app.4 iTerm2 is recommended in several programming books,48910 with engineer Jo Rhett and Mozilla's Tom Ritter describing it as one of the most popular terminal emulators.1112 Developer Mark McDonnel noted its additional features but criticized it for being less ubiquitous than tmux by lacking a Linux version.13
