openSUSE

openSUSE, formerly SUSE Linux and SuSE Linux Professional, is a Linux distribution sponsored by SUSE Linux GmbH and other companies. Its "Leap" variant shares a common code base with, and is a direct upgradable installation for the commercially-produced SUSE Linux Enterprise, effectively making openSUSE Leap a non-commercial version of the enterprise product. It is widely used throughout the world. The focus of its development is creating usable open-source tools for software developers and system administrators, while providing a user-friendly desktop and feature-rich server environment.
