GovTribe has been a pleased customer of Kinvey, the popular backend as a service provider, since version 2.0 of our app. If you are looking to build a product and would rather spend your time working on the client and not a backend, Kinvey is a great option. They offer a really solid platform, great client libraries, and responsive support.
As we've continued to expand our product offerings it became clear we needed better integration between the popular Laravel 4 PHP framework and our Kinvey backend. So we built an initial version and decided to open source it. Check out the repo on Github and let us know what you think. Comments, feedback, and pull requests all welcome.
