KaOS is a desktop Linux distribution that features the latest version of the KDE desktop environment, the Calligra office suite, and other popular software applications that use the Qt toolkit. It was inspired by Arch Linux, but the developers build their own packages which are available from in-house repositories. KaOS employs a rolling-release development model and is built exclusively for 64-bit computer systems.
