No, building on Coda is optional. You can build using anything, although the best product built using Coda will receive an additional Maker in Chief prize. 

We'll be giving out Silver kitties for winners in each category. If your submission is a Coda doc, you’re eligible for the Grand Prize: A trophy action figure in your likeness, and either a MacBook Air or 3d printer; so the world may know your makerness.
