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. Complete desktops are striven by GSDE and NEXTSPACE.

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.
