LibreOffice
#6 in Office Software · Rated 4.2
Open-source desktop office suite for cross-platform use
LibreOffice is a mature, open-source productivity suite maintained by The Document Foundation. It runs on Windows, macOS, Linux and more, and includes Writer, Calc, Impress, Draw, Base and Math. As an open-source project, it emphasizes interoperability with MS Office formats, ODF/ODT/ODS/ODP, and offline usage. In 2025 LibreOffice continued to release major maintenance updates (e.g., 25.2.x/25.8.x lines) that improve compatibility, stability and performance. It remains a compelling option for users who want a cost-free, privacy-respecting alternative with long-term community support. The lack of a built-in cloud-first workflow means it’s often paired with separate storage or collaboration layers, but its openness and extensibility keep it relevant in global markets.
