I’m not familiar with shopify but I’m about to start a shopify project for a client.

Can you elaborate on what the difference is between Hydrogen and a custom theme? Other than the tooling and template language I’m struggling to understand the conceptual differences.

Hydrogen is essentially a headless storefront, you have complete control over how your storefront is rendered, but it does come with boilerplate and helpers for some standard primitives that most people will want (e.g. carts).

Custom themes allow you to template on top of the Shopify front end, giving you less control.
