Crazy Eddie's GUI System is a free library for game developers that provides windowing and widgets for graphics APIs and engines where such functionality is not natively available, or is severely lacking.
Established in 2003, CEGUI sees continual, active development and remains one of the most powerful and most popular options for developers requiring an in-game GUI solution.
CEGUI is fully supported by the developers that created - and continue to develop - the library, and who are accessible via the project's dedicated internet forums and IRC channel.
