LibreOffice

LibreOffice is a free office suite whose licenses are copyleft, built to open and save most common document formats and standards. It is free to download, use and distribute, and it is backed by The Document Foundation, which represents an independent community of enterprises, developers and other volunteers.

This GitHub repository is a read-only mirror of the core code: pull requests are not accepted, contributions go through Gerrit, and downloading a zip is discouraged in favor of the project's source bundles. Developers can add features by working on the code base in C++, or write extensions using the SDK and UNO APIs, which are also used by macro scripting in StarBasic.

The README documents the minimum build and runtime baselines for Windows, macOS and Linux, plus iOS for LibreOfficeKit and Android builds. As is widely known, the suite includes applications for word processing, spreadsheets, presentations, drawing and databases. Its code is written mostly in C++.
