GNUstep Overview

GNUstep is a mature Framework, suited both for advanced GUI desktop
applications as well as server applications. The framework closely
follows Apple's Cocoa APIs and is portable to a variety of platforms
and architectures.

Read more about the GNUstep project, or the people behind it.

GNUstep offers Development tools for command-line and GUI
development, as well as the foundations for a Desktop environment,
which other projects can complete.

User experience

GNUstep provides the foundations for a portable desktop environment,
like offering the base Workspace API (implemented by the official
GWorkspace, but user-replaceable) and a set of useful but not
mandatory applications. The completion of a desktop environment is
done by other projects like the The GNUstep Application Project or
Etoile.

GNUstep provides an environment to easily develop advanced GUI
desktop applications as well as server applications.

GNUstep's core framework provides open source version of the Cocoa
APIs and tools for as many platforms as possible.
GNUstep provides a robust implementation of the AppKit and Foundation
libraries as well as the development tools including the advanced
interface designer Gorm (the InterfaceBuilder) and the IDE
ProjectCenter (ProjectBuilder/Xcode).
Thematic instead provides a user-friendly access to theming.

GNUstep seeks to be source code compatible with Cocoa, it can thus be
used to develop and build cross-platform applications between
Macintosh (Cocoa), Unix (Solaris) and Unix-like (GNU/Linux and GNU/
Hurd, NetBSD, OpenBSD, FreeBSD) platforms as well as Windows
GNUstep's main development language is Objective-C, but GNUstep is
not limited to that.
