Agree with some of the other commenters here – this seems really really smart, but only because I live and work deep in Shopify land. It was immediately obvious to me what this means, but there's plenty of Shopify merchants and partners who aren't even aware of the Lite plan, and if they know it's there, are unclear of the limitations.

I can definitely think of people who this would be great for – it's almost like headless commerce for the extreme low end. I'll be interested to see if you build this out further and what you decide to add. I'm surprised more haven't attempted to build full, wholesale replacement of Shopify's frontend outside of enterprise alternatives like Shogun Frontend.

A simple theming system and more customization would be a natural next step.
