The web interface works fine for me on macOs, as well as the CLI. But it's far from centralised configuration management. Sometimes you want to tinker, but sometimes you just want to deploy something (at friends/family) that works and when you return to it in a few months, to continue where you left off without going through every device's configuration or the documentation that is obvious not there as those side projects often don't allow you to 'allocate' time for that.
