Old news but related to the topic. There’s a built-in collabora CODE nextcloud app, but I guess the package from Markus shall perform at least the same or a bit better (unaware of the internal differences on the built-in app).
provides a built-in server with all of the document editing features of Collabora Online. Easy to install, for personal use or for small teams. It is a bit slower than a standalone server and without the advanced scalability features.
the built-in CODE server has some limitations in terms of performance
