PuTTY is a terminal emulator application which can act as a client for the SSH, Telnet, rlogin, and raw TCP computing protocols. The word "PuTTY" has no meaning,[1] though 'tty' is sometimes used to refer to the Unix terminals, as an acronym for 'teletype'.

PuTTY was first written for Microsoft Windows, but it has been ported to other operating systems including some Unix-like platforms. Mac OS and Mac OS X are still being ported, while unofficial ports have been ported it to the Symbian and Windows Mobile operating systems.

PuTTY is currently beta software. Licensed under the MIT License, and it is free and open source software.

  1. "PuTTY FAQ". [PuTTY is] the name of a popular SSH and Telnet client. Any other meaning is in the eye of the beholder. It's been rumoured that 'PuTTY' is the antonym of 'getty', or that it's the stuff that makes your Windows useful, or that it's a kind of plutonium Teletype. We couldn't possibly comment on such allegations.
