To allow the X11-based hacks to run natively on macOS and iOS, XScreenSaver contains a complete implementation of the X11 API built on top of Cocoa ('jwxyz').Rather than forking the code-base and re-writing the hacks to target different platforms, XScreenSaver contains a number of compatibility layers. About half of them use the X11 API, and about half use the OpenGL 1.3 API. It also means that a third-party screen saver can be written in any language or with any graphics library, so long as it is capable of rendering onto an externally provided window.įor historical and portability reasons, the included hacks are all written in ANSI C. This means that a programming error in one of the graphical display modes cannot compromise the screen locker itself (e.g., a crash in a display mode will not unlock the screen). This is an important security feature, in that the display modes are sandboxed into a separate process from the screen locking framework. The display modes (termed 'hacks' from the historical usage ' display hack') are each stand-alone programs. The XScreenSaver daemon is responsible for detecting idle-ness, blanking and locking the screen, and launching the display modes. The author considers Microsoft to be 'a company with vicious, predatory, anti-competitive business practices' Īnd says that, as one of the original authors of Netscape Navigator, he holds a 'personal grudge' against Microsoft because of its behavior during the First Browser War. There is no official version for Microsoft Windows, and the developer discourages anyone from porting it.

On Android systems, the XScreenSaver display modes work either as normal screen savers (which Android sometimes refers to as 'Daydreams') or as live wallpapers. On iOS systems, XScreenSaver is a stand-alone app that can run any of the hacks full-screen. On Macintosh systems, XScreenSaver works with the built-in macOS screen saver. On those systems, there are several packages: one for the screen-saving and locking framework, and two or more for the display modes, divided somewhat arbitrarily.

The free software and open-source Unix-like operating systems running the X Window System (such as Linux and FreeBSD) use XScreenSaver almost exclusively.

It was created by Jamie Zawinski in 1992 and is still maintained by him, with new releases coming out several times a year. XScreenSaver is a free and open-source collection of 240+ screensavers for Unix, macOS, iOS and Android operating systems.
