The application is open-source, which means it is continually improved by the community and can be extended with plugins and scripts.

iTerm2 is available for free on the Mac App Store and can be downloaded directly from the developer's website. It is compatible with macOS 10.14 and later, ensuring that users have access to the latest features and security updates.
