@Chris Howard - wpXtreme works fine in localhost. We tested it under MAMP and Vagrant and looks ok, but for any issue just contact us.

About WPDK, yes it includes options framework and metabox framework. We know Redux very well, but we took a different approach; we started from the low level stuff, so we add a lot of functionalities while Redux is mainly a "visual" framework. We are making WPDK better every day and if you want to contribute, test, use it, you're welcome!
