We're currently not aware of any live production sites up and running right now from our users. However, we do have an open Github repo (https://github.com/scaphold-io) with production-ready boilerplates for React and React Native with Relay. Within the week, we'll release more that use client frameworks like AngularJS and React with Apollo Client.

To provide examples of what we've seen so far, we've seen block chain models, chat bot apps, and music apps hosted on Scaphold to give you an idea of how complex they can get.
