The KDE Gear is a set of applications and supporting libraries that are developed by the KDE community, primarily used on Linux-based operating systems but mostly multiplatform, and released on a common release schedule.

The bundle is composed of over 200 applications. Examples of prominent applications in the bundle include the file manager Dolphin, document viewer Okular, text editor Kate, archiving tool Ark and terminal emulator Konsole.

Previously the KDE Applications Bundle was part of the KDE Software Compilation.

Software that is not part of the official KDE Applications bundle can be found in the "Extragear" section. They release on their own schedule and feature their own versioning numbers. There are many standalone applications like Krita or Amarok that are mostly designed to be portable between operating systems and deployable independent of a particular workspace or desktop environment. Some brands consist of multiple applications, such as Calligra Office Suite. There are several options for obtaining and installing KDE applications under Linux. Moreover, most of the KDE platform and applications have been ported to OpenBSD and NetBSD.

KDE SDK is a collection of two dozen distinct integrated (both within the SDK but also with other KDE applications, e.g. many work with Dolphin, the default file manager) applications and components that work with/are part of KDevelop, and is suitable for general purpose software development in a range of languages. It provides the tooling used to engineer KDE, and is particularly rich in tools to support Qt and C++ development, as well as the more fashionable Rust, Python, etc.

Various other packages are being built for testing on Android, although plans for some of the core parts of the SDK (e.g. Kate) have not been announced.
