GNUstep is a free software implementation of Cocoa (formerly NeXT's OpenStep) Objective-C libraries (called frameworks), widget toolkit, and application development tools not only for Unix-like operating systems, but also for Microsoft Windows. It is part of the GNU Project.

The GNUstep Base library is a free software package implementing the API of the OpenStep Foundation Kit (tm), including later additions. This documentation package describes the core of the Base library, for documentation on additional classes, see the BaseAdditions documentation package.

GNUstep is one of the GUIs. It resembles NeXT's OpenStep in many respects, including its libraries, widgets, and software development tools, and runs not only on Unix-like operating systems but also on Microsoft Windows.
