CocosBuilder is a free tool (released under MIT-licence) for rapidly developing games and apps. CocosBuilder is built for Cocos2d’s Javascript bindings, which means that your code, animations, and interfaces will run unmodified on iPhone, Android and HTML 5. If you prefer to go native all the way, there are readers available for cocos2d-iphone and cocos2d-x.
