Windows Terminal is the better SSH terminal for most Windows users now. It works with the built-in OpenSSH client, which Microsoft says has been included in Windows since Windows 10 version 1803 source. PuTTY is still useful. But it feels older, because it is older.
TLDR: Use Windows Terminal if you want tabs, themes, PowerShell, Command Prompt, WSL, and SSH in one clean app. Use PuTTY if you need a tiny standalone SSH tool, saved session profiles, or old-school server access. For example, if you open 10 SSH sessions per day, Windows Terminal can keep them in tabs, while PuTTY opens 10 separate windows unless you add extra tools. A junior admin managing 5 Linux servers will likely feel faster in Windows Terminal after one afternoon.
What are we comparing?
Windows Terminal is Microsoft’s modern terminal app. It can run PowerShell, Command Prompt, Azure Cloud Shell, WSL, and SSH. It is pretty. It has tabs. It supports split panes. It can look like a hacker movie, if you really want that.
PuTTY is a classic SSH client for Windows. It has been around for ages. It is small, free, and reliable. Many admins used it before Windows had a decent terminal story. Some still love it. Some keep it installed like a lucky screwdriver.
Both can connect to Linux servers, cloud machines, routers, and Raspberry Pi boards. The difference is how they feel while doing it.
Quick winner
Pick Windows Terminal if you use Windows 10 or Windows 11 and want a smooth daily SSH setup.
Pick PuTTY if you want a portable app, need special serial settings, or work in an old office where every server guide still says “open PuTTY.”
Honestly, it feels like PuTTY is the pocket knife from your dad’s toolbox. It works. It has stories. But Windows Terminal is the new toolbox with labeled drawers.
SSH setup in Windows Terminal
Windows Terminal uses the ssh command. That command comes from OpenSSH. You open a tab and type something like this:
ssh admin@example.com
That is it. If you use a private key, you can run:
ssh -i C:\Users\Sam\.ssh\id_rsa admin@example.com
You can also save hosts in your SSH config file. Then your command becomes tiny:
ssh webserver
This is great if you manage several machines. You can name them prod, staging, backup, or that one server nobody wants to touch.
SSH setup in PuTTY
PuTTY uses its own interface. You type the host name. You choose a port. You pick SSH. Then you click Open.
You can save sessions too. That is one of PuTTY’s best features. You can create a profile for each server. Then you just double-click later.
But keys can be annoying. PuTTY often uses .ppk key files. If your key is in OpenSSH format, you may need PuTTYgen to convert it. It drives me crazy that a simple key can turn into a mini side quest.
Tabs and daily comfort
This is where Windows Terminal wins hard.
- Tabs: Keep many SSH sessions in one window.
- Split panes: Watch logs on one side and run commands on the other.
- Profiles: Open PowerShell, Ubuntu, or SSH from one menu.
- Themes: Change colors without pain.
- Fonts: Use modern fonts with icons and clean spacing.
PuTTY does not do tabs by itself. Each session opens in its own window. That gets messy fast. If you connect to three servers, fine. If you connect to fifteen, your desktop starts looking like a junk drawer.
Speed and performance
Both are fast enough for normal SSH work. Typing commands feels instant on both, assuming your network is not awful.
PuTTY is tiny. It opens quickly. It uses very little memory. It is great on older machines.
Windows Terminal is heavier, but not in a scary way. On modern PCs, the difference is usually not worth worrying about. The extra features are worth the small cost.
If you are running a very old Windows box, PuTTY may feel snappier. If you are on Windows 11 with 16 GB of RAM, use Windows Terminal and enjoy your life.
Key management
Windows Terminal uses standard OpenSSH tools. That means your keys live in the usual .ssh folder. This is nice if you also use Git, WSL, Linux, or cloud tools.
PuTTY uses its own key format in many cases. This is not wrong. It is just another thing to remember. Another file. Another tool. Another “why is this not working” moment at 4:55 p.m.
For modern workflows, OpenSSH feels cleaner. It matches what most cloud docs use. It also works well with SSH config files.
Copy and paste
PuTTY has an old copy and paste style. Select text to copy. Right-click to paste. Some people love this. Some people paste a dangerous command by accident and age five years.
Windows Terminal feels more normal. You can use Ctrl + Shift + C and Ctrl + Shift + V. You can change shortcuts too.
This sounds small. It is not. Terminal work is full of small actions. If each one feels better, your day feels better.
Security basics
Both tools support secure SSH connections. The weak link is usually not the app. It is the user.
- Use SSH keys instead of passwords when possible.
- Protect private keys with a passphrase.
- Check host key warnings before clicking through.
- Keep Windows and your SSH tools updated.
- Do not save passwords in random text files. Please. Just do not.
PuTTY has been trusted for many years. Windows Terminal relies on OpenSSH, which is also widely used. For most people, both are safe when used properly.
Best for beginners
Windows Terminal is better for beginners who are learning modern SSH. The commands they learn will also work on macOS and Linux. That helps a lot.
For example, a new developer can learn:
ssh user@server
Then they can use that same command in Git Bash, Ubuntu, or a cloud shell. Nice and simple.
PuTTY is easier only if someone gives you exact screenshots. Click here. Type this. Press that. That can help in a locked-down office. But it teaches buttons more than SSH.
Best for sysadmins
Sysadmins may want both.
Use Windows Terminal for daily work. Keep PuTTY for odd cases. Serial console work is one example. Network gear is another. Some old devices behave better with PuTTY settings.
Windows Terminal is better for grouped work. You can open one tab for logs, one tab for package updates, and one tab for testing. Split panes make this even better.
Best for cloud work
Windows Terminal wins here too.
Cloud guides often show OpenSSH commands. AWS, Azure, Google Cloud, and many VPS hosts commonly give commands that start with ssh. You can paste those into Windows Terminal and move on.
With PuTTY, you may need to convert keys or adjust settings. Not always. But often enough to be irritating.
Where PuTTY still shines
PuTTY is not dead. Not even close.
- It is tiny. You can download it fast.
- It is familiar. Many teams already know it.
- It has saved sessions. They are easy to click.
- It works on old systems. That matters in some offices.
- It handles serial connections well. Great for network admins.
If you just need a simple SSH window, PuTTY still does the job. No drama. No big setup.
Where Windows Terminal wins
Windows Terminal wins as a daily workspace.
- It looks better.
- It supports tabs.
- It works with WSL.
- It uses standard OpenSSH commands.
- It fits modern dev and cloud work.
The big win is flow. You do not feel like you are switching tools every five minutes. SSH, PowerShell, Linux shell, and Git work can live in one place.
Final choice
Use Windows Terminal as your main SSH terminal on Windows. It is cleaner, more modern, and easier to grow with.
Keep PuTTY nearby if you support older systems, serial devices, or teams that still depend on PuTTY session files.
The simple rule is this: Windows Terminal for daily SSH. PuTTY for special cases. That combo keeps your setup simple. It also saves you from fighting your tools when the server is already being difficult.
