GNUstep Home Page

An open-source implementation of Cocoa, GNUstep is an API with an elegant design for building beautiful, cross-platform applications quickly.

Apps running on Mac, Linux/BSD, and Windows; though they can also run on many other platforms.

Apps use the native interface on Mac out of the box. They can run on Windows. Cocoa compatibility is up to macOS 10.15, and software developed using GNUstep can be built on macOS using Xcode.

Themes can be designed for Linux/BSD using the theming engine Thematic. Flexible enough to produce an original skin from scratch, or a familiar theme reminiscent of Platinum, Aqua, or the classic Windows 95.
