This is incredible. I have been wondering what a react port of jupyter would look like. Is this opensource ?

Any learning from multi-user deployment ? We are trying to do this internally inside our company and jupyter hub is a little hard to grok.

I know of a lot of people who would pay for a faster jupyter that can also be run as a standalone dashboard/script - without the heavy duty interactive kernels. Basically reduce the prototype-deploy loop.
