Nextcloud, Ionos and other partners are developing an open-source office suite under the project name „Euro-Office“ as an alternative to the market-dominant Microsoft Office.
The two partners are not starting from scratch, but have forked the components of OnlyOffice available as open-source code and want to build on them. In the summer, the software is then intended to replace the previous office component Collabora in Nextcloud and the Ionos Nextcloud Workspace. A ‘technical preview’ is already available on GitHub.
While this is a good news, I think they should move from github, you know microslop copilot…
Nextcloud uses GNU AGPLv3 and explicitly doesn’t use a CLA: https://github.com/nextcloud/server/blob/master/contribute/HowToApplyALicense.md. They do this to prevent themselves from relicensing it. So they can’t suddenly take the code and make it closed source.
Regarding OpenOffice. I used to be a big fan of OpenOffice more than a decade ago, but LibreOffice has become my open source office suite since then.
Apache OpenOffice (AOO) might still work, but there is no significant development (see commits of the last year https://github.com/apache/openoffice/graphs/contributors?from=2025-05-01&to=2026-04-02&type=c). Only one person is committing on a daily/weekly basis, but this person is in their own words not a developer (https://github.com/apache/openoffice/pull/202#issuecomment-2561915795). Most of the commits are ‘cleanup’ commits where whitespace or comments are changed https://github.com/apache/openoffice/commits/trunk/.
LibreOffice on the other hand is actively developed. Others who are actually involved explained this better than I can:
