    Doesn't mess up formatting like LibreOffice does.

    It's free and open source software. Compatible with most Microsoft Office documents. Doesn't track you at all.

    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.

    It does not require DotNet or Java to run. It runs natively on all WIN32 systems. That means it can be installed and run on Windows 95 right up to Windows 10 without any problems. It supports only open document formats, like the Rich Text format (*.RTF), that can be opened by any office suite on any operating system without any formatting errors. It is a very small download and install and also does not use any resources from the system.
