Formly is a React.js form builder and it's already available and open source as an npm package. It'm working on the web app that will allow you to create forms from the webapp and manage your forms into the code and see submissions directly from the webapp without touching your react code!
Please check back later. You can check the npm package here.
You can check the github repository here contributors are welcome!
