Apple’s Terminal app on the Mac is a great tool for diving into the command line, but it isn’t the only option available. The Mac Observer rounded up several alternatives to Terminal you can use to flex your macOS command line muscles.
Alternatives to Apple’s Terminal app for the MacMost people can use their Macs without ever needing to dive under macOS’s graphic interface. If you need to, or just want to, get some command line action going on the first place to go is Apple’s own Terminal app. It’s hiding in the Utilities folder inside the Applications folder on your Mac.
If the Terminal app doesn’t get you all excited, check out these alternatives:
iTerm2
iTerm2 lets you slice up a single window into multiple panes, each with its own independent session. It also sports a robust search tool, auto-complete for commands, multiple profile support, and more. iTerm2 is a free download, and the developers accept donations.
iTerm2 for the MacHyper
Hyper is a terminal app that also supports JavaScript, HTML, and CSS. The developers are always working on new features and you can create your own plug-ins, too. Hyper is a free download.
Upterm
Upterm calls itself “A terminal emulator for the 21st century.” It’s both a terminal app and an IDE, or integrated development environment. In other words, you can bang out terminal commands and code in the same app. Upterm used to be called Black Screen. It’s a free download.
Terminator
Terminator lets you group together multiple terminal windows in a grid. In fact, you can make some ridiculously complicated layouts if you want. It also supports tabs, and you can even type in multiple terminal instances at the same time. Terminator is a free download.
Terminator for the MacPowerShell Core
Serial Terminal Client For Mac
PowerShell Core lets you work with Microsoft’s PowerShell automation framework and work with the command line at the same time. The idea was to make a tool IT teams can use to automate routine tasks and configure systems, but it’s useful outside of that scope, too. PowerShell Core is a free download.
Alacritty
Alacritty is a terminal app that gets a boost from your Mac’s GPU for better performance. It isn’t overloaded with features, but doesn’t cut out what you most likely need. The developers say its OpenGL support makes it the fastest terminal app around. Alacritty is a free download.
Alacritty for the MacZOC
ZOC is a terminal app and SSH client. It emulates Emulations: xterm, VT220, TN3270, TN5250, Wyse, and QNX, plus supports communication SSH, Telnet, Rlogin, Modem, and Serial Cable. You can try out ZOC free for 30 days, and it’s priced at US$79.99.

MacTerm
MacTerm is billed as “a better Terminal” thanks to its tabbed window interface, 24-bit color support, powerful search support, macro support, session management, and more. MacTerm is free to download.
Cathode
Cathode is a full-featured terminal app that looks decidedly old school with its retro CRT-like interface. You can customize how your terminal window looks and work in full-screen mode—a great way to really confuse people who like to look over your shoulder at coffee shops. The app is also a text editor, so it’s handy for people who don’t need to get at their Mac’s command line. Cathode is priced at $4.99 and is available for download at Apple’s Mac App Store.

CoRD is a Mac OS X remote desktop client for Microsoft Windows computers using the RDP protocol. It's easy to use, fast, and free for anyone to use or modify.
2013-10-23: CoRD don't seem to work on 10.9 Mavericks. Check back next week.
Macs interact well with Windows, and with CoRD the experience is a bit smoother. Great for working on the office terminal server, administrating servers or any other time you'd like your PC to be a bit closer without leaving your Mac. CoRD allows you to view each session in its own window, or save space with all sessions in one window. Scale session windows to whatever size fits you—the screen is resized automatically. Enter full screen mode and feel like you're actually at the computer. The clipboard is automatically synchronized between CoRD and the server. For system administrators, CoRD creates a simpler workflow by allowing you to save server information, then quickly connect to that server by using HotKeys or the server drawer. This makes quickly connecting to a specific server easy, even when managing many servers.
