libreoffice

Here’s a comparison between LibreOffice and Apache OpenOffice. Both are free, open-source office suites descended from the original OpenOffice.org, but they diverged significantly after the 2010 fork.

1. Development Activity & Future-Proofing

Key takeaway: LibreOffice is the living, evolving project. OpenOffice is largely considered a legacy/maintenance-only project.

2. Microsoft Office Compatibility (.docx, .xlsx, .pptx)

This is one of the biggest practical differences when moving away from O365.

3. Features & Functionality

LibreOffice generally offers more and better features:

OpenOffice provides a solid but more basic and dated feature set.

4. User Interface & Usability

5. Security & Maintenance

For any production or organizational use, LibreOffice is strongly recommended from a security standpoint.

6. Performance & Stability

7. Licensing

8. Other Differences

Apache OpenOffice is only preferable in very specific cases, such as:

In your earlier context (using OpenOffice as a quick bridge to become independent of O365), the recommended practical path is:

  2. Migrate to LibreOffice within a few months (the switch is usually painless because file formats are very similar).

Most organizations and experts recommend skipping OpenOffice entirely and going straight to LibreOffice for the final independent setup.
