The easiest explanation is just to go to http://www.nodbg.com, and it will be pretty clear from there.
We wanted to ty and make a debugger that has a couple of things:
node-inspector is awesome, and Danny did a great job on it. It was a big inspiration for us, and we learnt a lot from the code. We did however want to improve upon the experience, as we wanted the above features.
windbg, Microsoft's kernel debugger, is something we were both familiar with. We think it has a pretty good mix of developer-friendly interface/features combined with low-level functionality, which we wanted to have in node.
Beyond the above, you can:
You can also run it both locally or remotely. There are no accounts, you will simply get a URL which you can share.
We also simplified the startup experience - you simply install, tell it which JS file to run or which process to attach to, and off you go. No need to manage multiple processes.
If you see this error:
throw arguments; // Unhandled 'error' event

You may have some zombie processes. Find them with
ps aux | grep node and kill
We've only tested it on Chrome, but it may work on IE9, Safari and Firefox.
The client probably only runs on Linux/OS X. We have only tested on OS X.
