PuTTY is described as 'Free and open-source terminal emulator supporting SSH, Telnet, and SCP. Portable, lightweight, and works offline to connect to remote systems securely' and is a leading terminal emulator in the os & utilities category. There are more than 100 alternatives to PuTTY for a variety of platforms, including Windows, Mac, Linux, Android and iPhone apps. The best PuTTY alternative is KiTTY, which is both free and Open Source. Other great apps like PuTTY are OpenSSH, MobaXterm, Tabby and Termux.
KiTTY is an opensource terminal emulator, forked from PuTTY , that adds many extra features to the original software.
It's pretty much stock Putty, but upgraded to modern standards.
Fork of putty. But more recently updated and fresher.
OpenSSH is a free version of the SSH connectivity tools that technical users rely on. OpenSSH encrypts all traffic (including passwords) to effectively eliminate eavesdropping, connection hijacking, and other attacks.
Up to date. One of the most trustworthy dev teams on the intenet.
There is no gui for connection management.
It's not terminal emulator, it's a utility to ssh'd to other mechine.
MobaXterm is an enhanced terminal app that brings the advanced features of a Unix-like command-line to Windows. It takes the power of Cygwin and wraps it in a sleek, visual interface that's super easy to use, lightweight and portable.
Arguably the best remote access program out there. Great compact interface, most features I've ever seen, works amazingly fast out of the box. The 10 session limit is what makes this Freemium, so if that is not a big deal for you, this is the software for you.
It's never let me down and is feature rich.
It's okay, but sessions are constantly disconnected after like a few minutes later. it also has some random cartoons all over the screen so annoying. not recommended.
Tabby is an infinitely customizable cross-platform terminal app for local shells, serial, SSH and Telnet connections.
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.
Experience a powerful Unix terminal on Android without the need for rooting. Customize with packages via Apt, run command-line tools, SSH, and program in C, Python, and more. Enjoy a full Unix environment with bash, zsh, mouse support, and external display compatibility.
Manage remote connections efficiently with this open-source tool, featuring a tabbed interface supporting RDP, VNC, SSH, Telnet, HTTP, and more protocols, without any ads.
If multiwindow (think 10+ ssh sessions at a time) is your thing this is the best alternative by far -- as a Linux admin and typically on 25+ servers at a crack this free app managed all servers no sweat.
Free with premium features
Termius is more than a mere SSH client – it’s a complete command-line solution that’s redefining remote access for sysadmins and network engineers. Securely access Linux or IoT devices and quickly fix issues from the comfort of your couch via laptop or phone.
Can be used on Linux, has a cleaner Interface compared to PuTTY & it's free for students.
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
ReTerminal is a sleek, Material 3-inspired terminal emulator designed as a modern alternative to the legacy Jackpal Terminal. Built on Termux's robust TerminalView.
Easy to use also have sftp
Very handy program. I have my ssh connection connect automatically at login. Does my reverse ssh tunnel and socks proxy and stays minimized in the system tray.
ZOC is a powerful and well-established terminal emulator and telnet client, well known for its outstanding user interface with tabbed multi session support.
Just let me say one thing: Try managing 200 hosts for 10+ clients in the host directory of Putty and ZOC.
Much nicer user interface.
tabs, ease of use, very easy to customize
