John, that's a great question. Unfortunately I couldn't find a good place to reference for an answer (the Readme has too much irrelevant content) - which is one of the reasons that I sent the announcement.
In short, it's a GUI debugger. It also allows you to do in line editing of the live code. And yes, the lack of a functional profiler did sound disappointing, but... The biggest complaint I have about JavaScript debuggers today is that they don't keep a call chain across promise resolutions. When things unwind to the main event loop, you can no longer see how the original request was formed. While talking in the W3 about Promises, we all noted that eventually the tooling would improve to support that (this was a conceptual concern at the time, and now I get to experience it as a practical problem). It isn't there yet, but hopefully someday...
