iTerm2 is a powerful terminal emulator for Mac with extensive customization and advanced features such as split panes and multiple profiles, making it ideal for developers and power users. FireCMD, on the other hand, is a Windows-based command line interface that offers easier navigation and user-friendly features, but lacks the depth of customization found in iTerm2.
