What KiTTY is
KiTTY is a free telnet and SSH client for Microsoft Windows, forked from PuTTY version 0.76. It supports SSH and Telnet, port forwarding, and basic session management. Session tools include filtering, portability, a launcher, and shortcuts for predefined commands. Automation can run logon scripts, supply passwords and commands, or execute a locally saved script on a remote session. The interface offers session icons, tray behavior, transparency, roll-up, and an always-visible option. Users can protect against accidental keyboard input and quickly duplicate a session. Listed integrations include the Internet Explorer SSH handler, pscp.exe, WinSCP, Cygwin, and cmd.exe. Other features include automatic saving, binary compression, clipboard printing, file association, and extra command-line options. A light chat server and text editor are integrated. KiTTY is designed only for Windows, with downloads available from Fosshub and documentation directed through its official website. The KiTTY plan costs nothing.
