Builder is currently in pre-alpha status and you are welcome to try a working demo.
The current demo of Builder can be deployed via an Amazon AWS server image and includes a set of demo components. These components provide the ability to construct demo web applications including a "hello world" app.
The demo components are designed to run on an Amazon AWS cloud instance. If you do not already have an Amazon AWS account sign up here: aws.amazon.com. Instructions on how to launch an AWS server instance with the ezStack Builder template is listed below.
