'''X.Org Server''' is the [[Free and open-source software|free and open-source]] implementation of the [[X Window System]] (X11) [[display server]] stewarded by the [[X.Org Foundation]].

Implementations of the client-side [[X Window System]] protocol exist in the form of ''X11 libraries'', which serve as helpful APIs for communicating with the X server.<ref>{{cite web|url=https://www.x.org/wiki/guide/xlib-and-xcb/#:~:text=At,server.|title=Xlib and XCB}}</ref> Two such major X libraries exist for X11. The first of these libraries was [[Xlib]], the original C language X11 API,<ref>{{cite web|url=https://www.x.org/wiki/guide/xlib-and-xcb/#:~:text=The%20original,%22Xlib%22.|title=Xlib and XCB}}</ref> but another C language X library, [[XCB]], was created later in 2001.<ref>{{cite web|url=https://www.x.org/wiki/guide/xlib-and-xcb/#:~:text=After%20many,XCB.|title=Xlib and XCB}}</ref> Other smaller X libraries exist, both as interfaces for [[Xlib]] and [[XCB]] in other languages, and as smaller standalone X libraries.{{citation needed|date=August 2022}}

The services with which the X.Org Foundation supports X Server include the packaging of the releases; certification (for a fee); evaluation of improvements to the code; developing the web site, and handling the distribution of monetary donations.{{citation needed|date=September 2011}} The releases are coded, documented, and packaged by global [[developer (software)|developer]]s.{{clarify|what is a global developer?|date=January 2012}}
