To add onto this, I have been using Libreoffice Online or Collabora Online for the last 4 years or so. I used to compile LOOL myself but eventually I just switched over to using the Collabora Online Development Edition that Collabora releases. I am using it integrated with Nextcloud.

I enjoy using it and it has been a life savior for the times I need to work on a document with someone else since I can just send them a share link for it. The fact that it uses leaflet which is meant for maps does mean that the latency to the server matters quite a lot to experience but I don't mind that much, personally, with my not great 120ms RTT to my server.

Hey - thanks for using Collabora Online (COOL) - we're doing a chunk of work to accelerate interactive editing, and lots of that starts to land in 22.05 - time-based document change compression (deltas), improved JS, reduced latency of event handling (particularly in the browser where handling websockets related to rendering & the DOM is a bit too 'exciting') - with lots of wins recently. Hopefully you can enjoy them in our next release coming soon.
