Shopify Hydrogen is Shopify's own React-based framework (built on React Router) for building headless storefronts that still run on Shopify's commerce backend. It gives developers full control over the frontend while Shopify still handles inventory, checkout, and order management — but you're still tied to Shopify as the commerce platform underneath, and typically to Shopify's Oxygen hosting for the intended deployment path.
If you want the same kind of composable, code-first storefront experience without being locked into Shopify specifically as the backend, Alokai lets you connect a modern frontend to any commerce backend you choose.

What's the best open-source alternative to Shopify Hydrogen?
Alokai is the closest match if what you want is a composable frontend layer that talks to any backend API, rather than being locked into Shopify's platform specifically.
