17 Free and Open-source Terminal Emulators for MacOS and Alternatives to the default macOS Terminal
A terminal emulator is a software application that allows users to access and interact with a command-line interface on their computer. It emulates the functionalities of a physical computer terminal, enabling users to execute commands, run programs, and perform various tasks through a text-based interface.
While macOS comes with a built-in terminal emulator called Terminal, some users may prefer alternative terminal emulators for various reasons. One common reason is to gain additional features and functionalities that may not be available in the default macOS Terminal.
These alternative terminal emulators often offer advanced features like customizable themes, split panes, synchronized input, enhanced search capabilities, and more, providing a more flexible and efficient command-line experience.
In this post, you will find the best open-source and free terminal emulator and shell alternatives for macOS.
