When it comes to making secure SSH connections, PuTTY has been a long-time favourite. Originally created for Windows, PuTTY is an open-source terminal emulator used by developers, system administrators, and IT professionals worldwide.
Even though modern systems like Windows 10/11, Linux, and macOS come with built-in SSH clients, PuTTY continues to be popular because of its user-friendly interface, portability, and additional tools.
In this guide, we’ll show you how to download and install PuTTY on Windows, Linux, and macOS, and why you might want to use it over built-in alternatives.
🚀 Why Use PuTTY Instead of Built-in SSH?
- Graphical interface – easier than command line for beginners.
- Portable version – run PuTTY as a standalone executable (no installation needed).
- Extra features – serial port connections, raw socket debugging, and session management.
- Cross-platform familiarity – same tool across Windows, Linux, and macOS.
