Martin Dorey ported Terminator to Cygwin. Elliott Hughes took Phil's terminal emulation and used it as a base upon which he could experiment with advanced terminal emulator features and continues to actively develop Terminator. Terminator was originally written by Phil Norman, who produced a more-or-less usable replacement for rxvt on his own between 21 April 2004 and roughly a month of development time.
Terminator is licensed under the GPL-2.0-or-later license. Terminator will run on any modern POSIX system running Java 6 or later.
It is available on Microsoft Windows, macOS, Linux and other Unix systems that use the X Window System. Terminator is an open-source terminal emulator programmed in Java.
