LibreOffice vs OpenOffice: Development Velocity

This article compares the development velocity of LibreOffice and Apache OpenOffice by analyzing commit frequency, release schedules, feature implementation, and developer community activity. While both office suites share a common heritage in the original OpenOffice.org codebase, LibreOffice maintains a rapid, modern release cadence driven by an active contributor base, whereas Apache OpenOffice experiences sluggish development characterized by infrequent maintenance updates and limited active contributors.

Commit Activity and Codebase Modernization

LibreOffice significantly outpaces Apache OpenOffice in day-to-day code contributions. Backed by The Document Foundation (TDF), LibreOffice receives tens of thousands of commits annually from hundreds of unique developers, including both corporate-sponsored engineers and independent volunteers. This high volume of contributions has allowed the project to remove vast amounts of obsolete legacy code, rewrite rendering engines, and modernize the underlying C++ architecture.

In contrast, Apache OpenOffice sees minimal commit activity. The project relies on a very small group of volunteer committers, leading to long stretches of time with negligible repository updates. Rather than modernizing the core architecture or eliminating technical debt, OpenOffice development is largely confined to minor maintenance and essential dependency updates.

Release Cadence and Security Patching

Development velocity is directly reflected in how frequently each project ships updates to end users:

• LibreOffice: Operates on a predictable, time-based release model. Major versions are released every six months, accompanied by regular monthly point releases containing bug and security fixes.
• Apache OpenOffice: Lacks a structured, time-based schedule. Releases occur irregularly, often with gaps spanning one or two years between minor point updates, resulting in slower turnarounds for critical security vulnerability patches.

Feature Evolution and Format Support

Due to its rapid development cycle, LibreOffice continually introduces major functional improvements. These include modern user interface options like the tabbed NotebookBar, enhanced export filters, native support for newer operating systems and CPU architectures (such as Apple Silicon and ARM64), and ongoing improvements to Microsoft Office format interoperability (DOCX, XLSX, PPTX).

Apache OpenOffice’s slower velocity has left the suite largely frozen in time. The interface, feature set, and file filters have seen very few changes over the past decade. It lacks full support for modern OpenDocument Format (ODF) specifications and struggles to maintain compatibility with modern proprietary office formats.

Community and Ecosystem Health

A software project’s development speed depends heavily on its surrounding ecosystem. LibreOffice benefits from commercial entities that provide paid engineering resources, alongside a strong community handling localization, documentation, and quality assurance. Apache OpenOffice suffers from a lack of active corporate backing, which limits its capacity to train new contributors, triage bugs, and drive long-term development roadmaps. Consequently, LibreOffice remains the active, evolving continuation of the open-source office suite ecosystem.
