Tabby vs PuTTY Comments

- Tabby is Free and Open Source
- Tabby is Customizable
PuTTY is not available for Mac but there are some alternatives that runs on macOS with similar functionality. The best Mac alternative is Tabby, which is both free and Open Source. If that doesn't suit you, our users have ranked more than 100 alternatives to PuTTY and five of them are available for Mac so hopefully you can find a suitable replacement. Other interesting Mac alternatives to PuTTY are PowerShell, Termora, rxvt-unicode and lterm.

PowerShell (including Windows PowerShell and PowerShell Core) is a task automation and configuration management framework from Microsoft, consisting of a command-line shell and associated scripting language built on the .NET Framework.

Since recently Microsoft has integrates OpenSSH in Windows 10 natively, so PowerShell (and Windows terminal) may now connect to SSH hosts from the command line, as you would do from LINUX or OS/X. PuTTY however has many more functions.
PuTTY is for remote terminal access, via SSH, Telnet, serial, etc.. Powershell is a shell for scripting not SSH or Telent access.
as stated by others here PuTTY is a TTY/network serial control application, and PowerShell is a local "terminal-like" application with no remote/TTY capabilities. there is no similarity here

Termora is developed using Kotlin/JVM and partially implements the XTerm protocol (with ongoing improvements). Its ultimate vision is to achieve full platform support (including Android, iOS, and iPadOS) through Kotlin Multiplatform.

Rxvt-unicode is a highly customizable terminal emulator forked from rxvt. Commonly known as urxvt, rxvt-unicode can be daemonized to run clients within a single process in order to minimize the use of system resources.

lterm is a vte-based terminal emulator for GNU/Linux systems. It is mainly used as ssh/telnet client but can be very easily configured to use any other protocol. Furthermore it can be a usual terminal on local host.


I think Tabby is overall easier and more smoother to work with. Specially since you get tabs, themes etc. If you just want to ssh into this than that I don't know why you wouldn't switch to tabby.
