KiTTY review
A free, open-source Windows client for SSH automation and saved sessions.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
KiTTY is a free, open-source SSH and Telnet client for Windows. Based on PuTTY 0.76, it is aimed at users who want a lightweight desktop connection tool with more automation than a basic terminal client. Its feature set suits administrators and technical users managing recurring remote sessions, especially when portability, saved sessions, and command entry matter more than team collaboration or cloud access.
Automation is KiTTY’s clearest strength. Session filtering, a session launcher, automatic logon scripts, predefined command shortcuts, automatic password and command entry, saved-script execution, and automatic session saving support repeatable workflows. SSH port forwarding adds another practical capability. The client also connects with pscp.exe and WinSCP, while its listed integrations include Internet Explorer, Cygwin, and cmd.exe. Portable operation and duplicate-session launching further support desktop-based workflows where quick access to stored connections is important.
The trade-off is a narrow platform and collaboration profile. KiTTY supports Windows and the SSH and Telnet protocols, with basic session management rather than a broader team or cloud workspace. Its integration with WinSCP and pscp.exe can complement file-transfer workflows, while users seeking a client centered on native file transfer, shared administration, or cloud collaboration should consider an alternative aligned with those needs. Choose KiTTY for free Windows SSH automation, port forwarding, and saved-session workflows; choose another option when cross-platform access or team-oriented management is the priority.
