CodeTasty provides smart collaboration tools, you can chat with others, share workspaces, see file tree updates, edit code together in real-time.
You can chat or share a workspace between regions, but real-time collaboration when editing files or updating tree is available only if you and your collaborators use the same region.
By default you only see file tree updates in real-time, but code collaboration is disabled as not everyone needs it and because it uses more of your CPU, RAM and network traffic. To enable it go inside IDE to Home (right sidebar) -> Settings (top bar) -> Editor and then toggle on the Collaboration.
