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.
General Information
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
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.
KDE Frameworks
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 Mac OS X
KDE software on these Operating Systems is in experimental state. Things might, or might not work properly at this point in time, largely depending on the app in question.
An installer for KDE applications on Windows is available on windows.kde.org. These are experimental packages. On TechBase you can find detailed installation instructions.
For Apple's OSX, there are technology previews of some applications available on mac.kde.org.
Android
KDE provides some software for Android under the KDE Community account on the Google Play Store.

About Plasma
Plasma by KDE
Simple by default, powerful when needed.

The Widget-Based Environment
Plasma is built on widgets, allowing you to move, mix, add, and remove just about everything to perfect your personal workflow.
Awesome with Android
The KDE Connect app for Android makes Plasma integrate seamlessly with your mobile device.
Fast & Efficent
Plasma is faster and more efficent than ever, using fewer resources than the previous generation desktop.
Featureful and Integrated
Plasma offers more thoughtfully integrated features than any other desktop environment for Linux or BSD.

Features
The KDE Frameworks are add-on libraries for coding applications with Qt.
The individual Frameworks are well documented, tested and their API style will be familiar to Qt developers.
Frameworks are developed under the proven KDE governance model with a predictable release schedule, a clear and vendor neutral contributor process, open governance and flexible LGPL or MIT licensing.
The frameworks are cross-platform and function on Windows, Mac, Android and Linux.
Organization
The Frameworks have a clear dependency structure, divided into Categories and Tiers. The Categories refer to runtime dependencies:
Functional elements have no runtime dependencies.
Integration designates code that may require runtime dependencies for integration depending on what the OS or platform offers.
Solutions have mandatory runtime dependencies.
The Tiers refer to compile-time dependencies on other Frameworks.
Tier 1 Frameworks have no dependencies within Frameworks and only need Qt and other relevant libraries.
Tier 2 Frameworks can depend only on Tier 1.
Tier 3 Frameworks can depend on other Tier 3 Frameworks as well as Tier 2 and Tier 1.
Highlights:
KArchive offers support for many popular compression codecs in a self-contained, featureful and easy-to-use file archiving and extracting library. Just feed it files; there's no need to reinvent an archiving function in your Qt-based application!
ThreadWeaver offers a high-level API to manage threads using job- and queue-based interfaces. It allows easy scheduling of thread execution by specifying dependencies between the threads and executing them satisfying these dependencies, greatly simplifying the use of multiple threads.
Breeze Icons. KDE Frameworks includes two icon themes for your applications. Breeze icons is a modern, recogniseable theme which fits in with all form factors.
KConfig is a Framework to deal with storing and retrieving configuration settings. It features a group-oriented API. It works with INI files and XDG-compliant cascading directories. It generates code based on XML files.
KI18n adds Gettext support to applications, making it easier to integrate the translation workflow of Qt applications in the general translation infrastructure of many projects.
Kirigami is a responsive UI framework for QML.
Examples
GammaRay is a cross platform (Linux, Windows, Mac) inspection tool for Qt apps from KDAB. It uses KSyntaxHighlighting to colour text it shows.
LXQt is a simple desktop environment for Linux. It uses Solid for hardware integration, KWindowSystem for window management and KIdleTime for power management.
Good looks are added with Oxygen Icons, one of our icon theme frameworks.

Mailing lists are a way for large groups of people to keep in touch. It works like an email contact group and to subscribe, you give your email address to the server. You can then send mail to that distribution address and it will go to everyone who is subscribed.
The KDE community has several mailing lists online. You may subscribe and unsubscribe to many of these lists and some others by going to the
mailman interface.
Older articles can be found in the mailing list archive.
Links to application specific lists can be found on their appropriate page.
You can also find a detailed index of KDE related mailing lists.
Additionally, there is a KDE newsgroup called comp.windows.x.kde which you can search here.
Wiki
The KDE community offers Userbase as an online source of information regarding its applications.
You can find links to the application pages by searching on Userbase itself,
or you can use the link on the application's page.
If you are looking for technical information regarding KDE, you may find Techbase to be more helpful.
Chat Channels
Community support is available in the KDE Matrix Room.
See the List of KDE Matrix Rooms for more specific channels.

Our policy regarding the sites listed above is simple: If somebody goes through the
trouble of creating a KDE website, then we will include it in this

preference for what to call their geographical area (e.g., calling the
Taiwan site "Taiwan" instead of "China").
