@lukecooperatus That’s true, OnlyOffice can be used too. However, Nextcloud Office is better integrated with everything else in Nextcloud. Also, OnlyOffice focuses on MS compatibility while Collabora’s focus is open standards files. Both will work, depending on what you really want and care about.

@Synther Nextcloud offers Nextcloud Office which uses Collabora Online based on LibreOffice. You can manage all sorts of documents, including slides. You can self-host it or sign up with a managed service provider.
