CDK is a library written in C that provides a collection of widgets for text user interfaces (TUI) development.

The widgets wrap ncurses functionality to make writing full screen curses programs faster.

Perl[1][2] and Python[3] bindings are also available.

It was originally written by Mike Glover, introduced as version 4.6 in comp.sources.unix.

[4] The other version was extended beginning in May 1999 by Thomas Dickey.
