This looks like a pretty slick, mobile-compatible photo gallery, but without the code it isn't very useful. They talk about Chromatic like a real product, but "free web service" basically means "demo".
I would love for the code to be released, something similar and selfhosted with a simple static backend (or my favorite: Kirby) would live on any low end box. Please consider selling the design and assets on Themeforest.
