To make tools that generate React/Vue code work well you have to go far and beyond what most of the front-end oriented tools currently do...At Codesolvent we're taking a different tack..some samples:
yes we do have users, there is a cloud hosted version in the works.
It is an object model based solution so it does take some getting used to...basically imagine your vue/react application constructed as an object model, the product provides a UI environment for creating and manipulating that model.
Of course there is always room for improving the workflow so what you see today is definitely not what we envision the final state to be. What we are really excited about is the underlying tech which is going to allow different UI based solutions.
