This is a VistaPanel Add-on. It serves as a replacement to the original Site Builder - this is using the Site.Pro Site Builder.
You just need fill out the form to use it - very easy.
You don't need an API key or anything else because my API powers this.
It has been tested on my local PC before, and it worked fine. I am not sure about the "Render" option, though. However, the Node Express Host will work.
