Getting KDE Software
As KDE produces Free Software, you can download and install KDE programs in most cases free of charge. On this page can read below about various ways to get KDE software.
KDE software consists of a large number of individual applications, Plasma, a desktop workspace to run these applications, and KDE Frameworks, a set of libraries they are build upon. You can run KDE applications just fine on any desktop environment. KDE applications are built to integrate well with your system's components. By using also Plasma, you get even better integration of your applications with the working environment while lowering system resource needs.
Plasma runs fine on relatively recent PCs, but it also works great on older machines with more constrained resources.
To install our software on Linux pick a distro and grab the packages you want. See Get KDE Software on your Linux Distro.
KDE Plasma - Our Desktop
Installing Plasma on your system is easy if you use the major Linux distributions; it's included in nearly all of them! A partial list can be found here: Distributions Shipping KDE Software
There are instructions available for building the source code. Building from source code is not recommended for normal users as it requires knowledge of software development tools.
KDE applications run fine on most Linux, BSD systems. In these cases, the recommended way to install a KDE application is to use your operating system's software management tool to install it. It comes included with most Free operating systems.
The KDE Frameworks are a set of libraries built on the Qt framework, providing everything from simple utility classes to integrated solutions for common requirements of desktop applications. You can download them at http://download.kde.org/stable/frameworks/ or read the online documentation.
Windows and macOS
An installer for some KDE applications on Windows is available from the KDE on Windows project.
For Apple macOS systems, some applications have been made available by their developers. A list of these can be found on the Community Wiki.
KDE provides some software for Android under the KDE Community account on the Google Play Store.
