Hi @Mario, @Tex You may already have contacted sales…:
I am a user, I am 99.9% sure that there are simply 2 versions of Collabora Online, and both without limitations.
*CODE is the free version, this version is released with the newest features, so it can potentially be buggy.
*Collabora Online is the subscription version, its binary releases very closely follow CODE, I believe that sometimes it lags a bit behind CODE and it may includes backports of new good bits of CODE, particularly when there are other troublesome new features in CODE. I imagine Collabora prefer subscriptions.
*A Collabora Online server can integrate simultaneously with several cloud solutions and also things like Alfresco, Kolab, Mattermost, Moodle, Nuxeo, SharePoint and others.
*Collaborative real-time editing a single document in Collabora is possible, whereas Microsoft for the web locks paragraphs or sections of documents to a single user, creating deadlocks when this fails to work properly, and is probably not proper collaborative real-time editing.
