   Top Positive Comment by Korwin · Nov 10, 2019

   Free, Windows, full Microsoft Office (.doc, .xls), Microsoft Office Open XML, OpenDocument, and Portable Document Format support.

   Really bad UI and UX, no cloud save, no collaboration tools, use this of you wanna flashback to early 2010s

   Positive comment by social-remodeler · Oct 2, 2024

   LibreOffice is free and open source and also brings in free document types which are not restricted by Microsoft.

   Libreoffice lacks in some point of support Microsoft only document styles but you can create fully functional documents shareable with any Microsoft office Suit.

   CryptPad vs Microsoft 365 Copilot Comments

   Positive comment by Shaz Shah · Jul 28, 2025

   I like Cryptpad as an alternative to M365, where it allows you to self-host your own office suite, which looks like an instance of OnlyOffice hosted in the "cloud" while respecting E2EE and is open source. If you'd rather use the cloud than self-host you can use a public instance or a paid plan for hosting and storage.

   Positive comment by kaspian · Jan 30, 2023

   Great thing to selfhost, it uses E2EE

   Don't use it! Apache OpenOffice is a dead project. For many years there's been no real serious updates to the project.

   Negative comment by KuboFHromoslav · May 17, 2025

   OpenOffice was a great alternative when it was in really active development. But for more than a decade it stands on the same place without meaningful movement and it is very unfortunate. Rather use LibreOffice, which stands on the great legacy of OpenOffice but is in active development.

    In my opinion WPS gives you the closest thing to MS Office. If you are familiar with MS Office you should be able to use WPS right away. This is the main reason I prefer it to OpenOffice or Libre Office

    Calligra Suite vs Microsoft 365 Copilot Comments

    Comment by Shaz Shah · Jul 28, 2025

    Calligra Suite's interface kinda resembles iWork (is it still called that?), which would come as a shock to those coming from Office. Unfortunately, I didn't have a stable experience using it on my device running Zorin OS. It also lacks collaborative features.

    SoftMaker FreeOffice vs Microsoft 365 Copilot Comments

    Top Positive Comment by fris · Feb 22, 2022

    I was using only Libre Office for years on Linux. Now I use FreeOffice and Latex via VS Code the most. FreeOffice is fast and streamlined, the UI is well built and looks good, very compatible with MS proprietary formats. It's also available for several platforms. There's a commercial alternative with more features too if you need support. Just try it.

    Misleading name, it isn't free.

    Positive comment by Entterprice · Oct 12, 2026

    FreeOffice for students, bootstrapped startups, and casual home users — free, light, offline, good enough. Microsoft 365 with Copilot for growth-stage teams where collaboration and AI actually save time. Fintechs must use Microsoft 365, ideally Business Premium plus Copilot — audit trails, DLP, data residency, and permission-bound AI aren't optional. FreeOffice stays personal, never production in finance.
