What about tmux did you find complex?

There’s a lot of stuff to do and configure. You need to set up ssh forwarding and some times it may mean configuring firewalls, ssh keys, or VMs/servers.

GitDuck is just one command, the other peers don’t need to do/install anything and very easy to control permissions (read only vs read+write)

Those are good points. Sometimes after I've done something nontrivial I treat it as the opposite and forget how difficult it might have been.
