Have you ever tried CakePHP? Yes, it’s a rapid application development framework that allows you to rapidly build web applications. But recently, I found something really great, ModelBaker. It’s a desktop application that makes development even faster. Building a blog in 3 minutes? Yes! That’s awesome. I’ve tried ModelBaker myself on it’s beta testing phase, and I have to admit, this application is definitely helpful for any web developer.
Taken from ModelBaker site:
