Sorry to hear about the shutdown, and it looks like it was a pretty useful tool. Great that they open sourced it.

The source code looks very interesting (and a bit unusual for a React app.) [1]

Looks like Coffeescript + "Coffeescript JSX", which I hadn't heard of before.

I didn't look too closely, but I didn't see how they're doing state management in the editor. No Redux in the package.json [2]. I was hoping that I might be able to repurpose some of this for a new project I'm working on, but it all looks very foreign to me [3], and the file organization doesn't seem to follow any conventions that I'm familiar with.
