   ONLYOFFICE vs LibreOffice Comments

   Top Positive Comment by John Fastman · Mar 6, 2017

   ONLYOFFICE is less functional than Libre Office, but it is open source and has the following advantage I find useful: It opens all Microsoft Office .doc and .docx files with better fidelity than Libre Office does. Especially those with embedded vector graphics, which Libre sometimes screws up. The functionality is more like Google docs or something (e.g. no plugins, etc.). But it's good to have around.

   Top Negative Comment by Daltro Auguso Campanher de Souza · Sep 27, 2022

   Onlyoffice is realy promising and amazing piece of software. However, I find it to work really bad in (poor) machines with less RAM (4gb or less). Optimization is way worse than what a software with maturity as LibreOffice can get. Also, like what other people said here, LibreOffice have more features at all, it's a more mature and reliable project.

   Closer to Microsoft Office than LibreOffice. That's what most folks need.

   Apache OpenOffice vs LibreOffice Comments

   Top Positive Comment by gregorijus · Sep 4, 2016

   Lightweight and stability.

   Top Negative Comment by 78jmb6dk · Apr 9, 2022

   OpenOffice seems to be end-of-life. It doesn't receive as many code contributions as LibreOffice and has fewer features. LibreOffice is a successor to this project and is probably better for most users.

   Negative comment by Kelson V · Jan 16, 2026

   Oracle totally squandered this project after they bought Sun. By the time they handed it off to Apache it was too little, too late, and most of the active work had moved over to LibreOffice. Apache's basically kept it on life support for the last decade.

    ZetaOffice vs LibreOffice Comments

    Positive comment by Not Yourbusiness · Nov 8, 2025

    Interesting. A free alternative to in-web Office 365.

    Perhaps a collaboration between ZetaOffice and LibreOffice would be in it's place.
