iTerm2

iTerm2 is an open-source terminal emulator for macOS that serves as a feature-rich alternative to the built-in Terminal.app. It aims to provide advanced capabilities for users who work in command-line environments, such as developers, system administrators, and power users.

Its core features include split panes and a tabbed interface for organizing multiple sessions, extensive search and copy history, and support for 24-bit color. It also offers programmable triggers, autocompletion, and a configurable hotkey window for quick access to a shell session.

Other notable capabilities include instant replay to review past terminal output, tmux integration for managing sessions, and support for inline images via iTerm2's image protocol. A Quake-style dropdown window and reusable profiles improve workflow and accessibility across projects.

iTerm2 provides shell integration, which enhances prompts and autocompletion, and allows scripts and status information to be surfaced in the terminal. It stores preferences per profile, including fonts, colors, key bindings, and notification settings, and can be controlled via AppleScript and other automation interfaces.

Development and licensing: iTerm2 is an open-source project hosted on GitHub and maintained by volunteers and contributors. It is released under an open-source license and is widely used in macOS development and system administration communities.
