I think Collabora Online uses or is built on LibreOffice. It’s a subscription service but you can host it yourself for free (I think for personal use). I’ve not tried either. I’m pretty sure the Collabora team are big code contributors to LibreOffice. If I got anything wrong I hope someone will correct me.
Can I pay KDE to put ads in all that empty space?
