Looks like it has the non-reactive Jupyter style notebook as opposed to the reactive-style Observable one though. I do prefer the latter by a large margin to be honest. Are there any plans to also support reactive notebooks?
I’m working on an open source notebook with built-in support for React and Typescript. It also comes with a built-in reactivity model and evaluate-as-you-type. To be open sourced soon, but preview version already available at https://www.typecell.org
There is a starboard-observable package which uses the same open-source reactive runtime as observablehq
