OpenOffice.org is a discontinued open-source office productivity software suite, from which
Apache OpenOffice and
LibreOffice descended.

Apache OpenOffice 4.0.0 was released for x86 versions of Microsoft Windows XP or later, Linux (32-bit and 64-bit), and Macintosh OS X 10.4 or later. Other operating systems are supported by community ports; completed ports for 3.4.1 included various other Linux platforms, FreeBSD, OS/2 and Solaris SPARC, and ports of 3.4.0 for Mac OS X v10.4–v10.5 PowerPC and Solaris x86.

LibreOffice is officially developed for Microsoft Windows (IA-32), Linux (IA-32 and x86-64) and OS X (IA-32). Community ports for FreeBSD, NetBSD, and OpenBSD are maintained by contributors to those projects, respectively. A community port for OpenIndiana is in development.
In 2011 plans were announced to port LibreOffice to both Android and iOS. A-EON Technology announced in 2012 that a port of LibreOffice is underway for their AmigaOne X1000 computer running the latest AmigaOS.
LibreOffice Online will allow for the use of LibreOffice through a web browser by using the canvas element of HTML5. Development was announced in October 2011 and is ongoing. It has not yet been released.
