Greetings stranger! Welcome to the wonderful world of KDE. KDE is a worldwide project dedicated to bring the best software to you - for free. Read on and find out what we can offer you and what you can do for us.

An International Community

KDE is more than just software. It is a community made up of programmers, translators, contributors, artists, writers, distributors, and users from all over the world. Our international team is committed to creating the best free software for the desktop and mobile. And not only contributors, but users and fans of KDE software can be found throughout the entire globe, giving help to other users, spreading the news, or just simply enjoying the experience.

KDE started life as a desktop environment over 20 years ago. As activities have grown, KDE is now an international team that creates Free and Open Source Software.

What this means in practice is that the many programs from the KDE community work together to give you the best possible computing experience. Does that mean you can't use a KDE application if you don't use the KDE desktop? Not at all. With the help of one or two extra libraries the applications can be used on almost any Linux desktop. What's more, increasingly that software runs on a variety of other platforms. You can now find many KDE applications running under Windows and Mac OS or other devices such as smartphones and tablets.

Tons of Free Software

KDEは単なるソフトウェアであるだけではありません。それはフリー(自由)ソフトウェアなのです。例え技術的、法律的な問題に深く関わらないとしても、これはユーザとして重要なことです。何故でしょうか? フリーソフトウェアであることで、あなたは好きなところで、好きなように、アクティベーションキーやインストール制限などなしに、自由に利用できるのです。また、あなたはこのソフトウェアを他の人たちと自由に共有することができます! 素晴らしい強力なソフトウェアをあなただけでなく、あなたの家族や友達も享受することができるのです。

  • the Plasma workspace - the user interface element, customized for different devices such as PCs, notebooks, or mobile devices
  • the KDE Frameworks - most KDE applications are built with the help of a unified framework. Do you also want to write a killer app? The KDE Frameworks can help you with that!
  • KDE Applications - software programs that are written to utilize the platform

Getting KDE Software

If you are using Windows or Mac OS, a growing number of KDE apps such as Krita or Kdenlive are available for you to download and install. You'll find installers on their pages.

As of right now, some KDE software is for various reasons only on Linux, a free operating system that you can try right now. The community produces KDE neon, a downloadable Ubuntu Linux-based operating system which includes the newest version of KDE.

Helping KDE

KDE can only exist because thousands of dedicated contributors from around the world have given their time. You can help too! There is a task for everybody, and we are looking forward to see how you are going to make KDE better.
