iTerm2 review
A capable Mac terminal with advanced panes, profiles, session restoration, and automation.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
iTerm2 is a free, open-source terminal emulator for macOS and a replacement for Apple’s Terminal. It is aimed at Mac users who want more control over terminal layouts, shell sessions, remote workflows, and automation. The feature set covers tabbed terminal windows, vertical and horizontal split panes, configurable profiles, automatic profile switching, shell integration, search, session restoration, and saved arrangements. GPU-accelerated rendering and inline image display add capabilities beyond basic command-line windows.
The published offering is straightforward: iTerm2 is distributed as free software, with no paid tier described. Its source code is publicly available under the GPL, and the project is maintained by George Nachman and contributors. For users choosing a terminal based on workflow depth rather than a subscription model, the combination of profiles, saved arrangements, session restoration, and flexible pane layouts makes it suitable for organizing recurring local or remote sessions. SSH-aware shell integration and tmux integration also fit users who move between local terminals and remote environments.
iTerm2’s strongest distinction is its automation and session-management depth. A documented Python scripting API and RPC automation provide ways to extend or control terminal workflows, while configurable profiles and automatic switching can adapt sessions to different contexts. The trade-off is platform coverage: the supported desktop platform is macOS, so users who need the same terminal across multiple operating systems should choose a broader alternative. iTerm2 is a strong fit for Mac users who value rich terminal organization, SSH-related workflows, GPU rendering, and scripting. It is less suitable for teams seeking a cross-platform terminal standard or a product centered on collaboration beyond terminal sessions.
