OpenOfficeLibreOffice

OpenOfficeLibreOffice refers to two open-source office suites that share a common origin in OpenOffice.org. Today the two main projects are LibreOffice and Apache OpenOffice. LibreOffice is developed by The Document Foundation; Apache OpenOffice is developed by the Apache Software Foundation. Both suites are designed to provide word processing, spreadsheets, presentations, and other office applications across multiple platforms.

OpenOffice.org originated as a project from Sun Microsystems, which was acquired by Oracle. After Oracle's stewardship, a community fork led to LibreOffice in 2010. In 2011, Oracle donated OpenOffice to the Apache Foundation, creating Apache OpenOffice. LibreOffice diverged with its own governance and development focus.

LibreOffice includes Writer, Calc, Impress, Draw, Base, and Math; Apache OpenOffice includes Writer, Calc, Impress, Draw, Base, Math. Both support the OpenDocument format (ODF) as standard and offer some compatibility with Microsoft Office formats, though compatibility may vary by feature. Both provide extensions and templates; both run on Windows, macOS, Linux, and some BSD variants; both support multiple languages.

LibreOffice is known for more frequent updates and broader community participation; Apache OpenOffice has a slower release cadence and governance under Apache. The user base includes individuals, schools, and government agencies; Linux distributions commonly include LibreOffice by default, while OpenOffice persists in some distros and organizations.

Both suites continue to compete for users seeking a free, open-source alternative to proprietary office software, with LibreOffice generally seen as more actively developed, while Apache OpenOffice offers a more conservative feature set.
