For those that don't use Laravel, PuPHPet[0] is a great utility to generate local and deployable pre-made Vagrant boxes with a variety of apps. If you're interested in testing the Laravel Forge images locally, they use Homestead[1] which is the official Vagrant image for the Laravel Framework (as of 4.2)
Problem with PuPHPet is that it's really buggy. I've used it more than 10 times (also recommended it to colleagues) and we managed to provision a box correctly maybe on two occasions.
Every time there was a different bug. Either something didn't install, or the config files weren't being loaded etc. I ended up learning Puppet because of it, so I guess some good has come of it ..
I reported a couple of bugs and they were taken care of, actually. That said, I turned to PuPHPet specifically because I don't have time to tinker around.
