My team and I have been working on a software simulator. It deconstructs software projects, creating simulations of all components (front-end and back-end) in isolation and in context, so you can easily see, test, and share any area of an application or the application as a whole. The blog post has more details.

It's starting to work pretty well and we're looking for people who might be interested in trying it out. Would also love to hear any feedback or questions people have about the concept.
