Quick set up with easy-to-follow documentation and a great number of native features makes it one of the most powerful wrappers built on top of Jasonelle. The best part is that it's open source, so you have full control to build in features at any stage.
I recently saw this product on Product Hunt and I have to say, I am really impressed. The fact that it is free to use and open for the community to improve is definitely a plus. Great job to the team behind it!
