I have been a user of floobits for a few projects. I’ve used it both for remote collaboration and to “stream” my code for a presentation. Regarding the remote collaboration, the product is not working well. It is difficult to connect with someone else, when the connection goes down for whatever reason then reconnecting and recovering changes doesn’t work well. We cannot use 100% of sublime text features, most importantly auto-complete and undo/redo, both leave the editor in a strange state like if the cursor was moving around. Regarding the presentation feature, to stream the code on a online read-only editor hosted by floobits, the editor itself isn’t very feature rich and the font (but that’s a personal opinion) isn’t great for coding. The TLS certificate on their website hasn’t been renewed since may (I’m posting in october) and their github shows no activity for the past years.
With the people I collaborate with, we now basically open vscode to benefit from their live-share feature whenever we want to collaborate in real-time (think peer-programming)… even if we all are sublime users.
