YaST is [[free software]] that [[SUSE Linux|SUSE]] has made available under the [[GNU General Public License|GPL]] in 2004.<ref name="YaSTGPL">[https://www.heise.de/newsticker/meldung/YaST-wird-freie-Software-95583.html heise.de:] YaST wird freie Software (in German)</ref><ref>{{cite web|title=Novell Launches Open Source Systems Management Project|url=http://www.novell.com/news/press/archive/2004/suse_archive/yast.html|publisher=[[Novell]]|access-date=2008-03-01}}</ref> 
It is a tool for administering and maintaining a SUSE Linux installation. It allows administrators to install software, configure hardware, set up networks and servers, and more.

A feature of YaST is that it contains both [[Graphical user interface]] (GUI) and [[Text-based user interface]] (TUI) (with [[ncurses]]) front ends. This is especially useful for non-GUI installations such as servers, for system administration over slow Internet connections, and for when one is unable to boot into a graphical X server but still requires an advanced user interface to the package manager (for example, a novice user trying to downgrade an [[X.Org Server|Xorg]] package to fix a graphical installation).

YaST offers package management functionality through the [[ZYpp]] project.<ref>{{cite web|title=Libzypp |url=http://en.opensuse.org/Libzypp |publisher=[[openSUSE|opensuse.org]] |access-date=2008-04-27 |url-status=dead |archive-url=https://web.archive.org/web/20080330222935/http://en.opensuse.org/Libzypp |archive-date=March 30, 2008 }}</ref> The first ZYpp enabled package management YaST applications had performance problems and long start up times, but was improved in the 10.2 and 10.3 releases. Starting with openSUSE 11.0 alpha 3, ZYpp was integrated with the SAT solver project, making YaST and Zypper faster than other rpm based package managers.<ref>{{cite web|title=fast package management|url=http://duncan.mac-vicar.com/2008/02/07/fast-package-management/|archive-url=https://archive.today/20130908215859/http://duncan.mac-vicar.com/2008/02/07/fast-package-management/|url-status=dead|archive-date=September 8, 2013|publisher=duncan.mac-vicar.com|access-date=2008-04-27}}</ref>

YaST used to include SaX and SaX2, the Suse Advanced X configuration. SaX was re-written as SaX2 in SuSE Linux 6.4. SaX1 was removed in SuSE Linux 8.1 and SaX2 was removed from the YaST Control Center in openSUSE 11.2. SaX2 was removed completely in openSUSE 11.3. The [[GTK]] interface was removed in openSUSE Leap 42.1.

YaST often receives updates and improvements in Tumbleweed and between versions of Leap. openSUSE Leap 15.1, for example, saw improvements to the YaST interface for managing firewalls including the addition of an interface in the command line version of YaST. In this same release of openSUSE Leap, YaST now has an updated logo and improved partition management module.<ref>{{cite web|url=https://news.opensuse.org/2019/05/22/opensuse-community-releases-leap-15-1-version/|title=openSUSE Community Releases Leap 15.1 Version|website=openSUSE News|date=22 May 2019|language=en|access-date=2019-05-31}}</ref>

YaST formerly utilized a bespoke scripting language known as YCP; in OpenSUSE 13.1, YaST was rewritten in [[Ruby (programming language)|Ruby]].<ref name="YaSTruby"/>

On OpenSUSE Leap 16.0, YaST will be deprecated. The web-based [[Cockpit (software)|Cockpit]] project is being adopted to supplant the YaST Control Center, a web-based installer known as Agama will replace the YaST installer, and Myrlyn will be introduced as a new Qt-based ZYpp front end with no dependency on YaST.<ref>{{Cite web |title=SUSE's D-Installer Taking Shape As New Web-Based Linux Distro Installer |url=https://www.phoronix.com/news/D-Installer-0.4 |access-date=2025-05-06 |website=www.phoronix.com |language=en}}</ref><ref>{{Cite web |title=Formerly Known As YQPkg, Myrlyn Package Manager GUI Adds Repository Configuration |url=https://www.phoronix.com/news/Myrlyn-Repo-Configuration |access-date=2025-05-06 |website=www.phoronix.com |language=en}}</ref><ref>{{Cite web |title=SUSE's YaST Team Drops Cockpit With New Installer Code |url=https://www.phoronix.com/news/SUSE-Agama-Ditches-Cockpit |access-date=2025-05-06 |website=Phoronix.com |language=en}}</ref>
