@mellifluousbox@mastodon.social @danie1@mastodon.nl @libreoffice@fosstodon.org In short: LibreOffice is the desktop version for local work, while Collabora Online is built on the LibreOffice codebase but runs as a server, letting multiple users edit the same document simultaneously in a browser. They're independent programs though. Your local LibreOffice doesn't talk directly to a Collabora server, Collabora just uses the same rendering engine internally. Collabora always needs a hosting platform like Nextcloud, OpenCloud,ownCloud or similar behind it to actually manage the files. And yes, OnlyOffice does the same collaboration trick, just with its own separate engine instead of LibreOffice's code.
