Headless Shopify decouples or separates the Shopify e-commerce platform’s backend from its frontend presentation layer. Unlike traditional monolith tightly coupled architecture, the Shopify headless architecture acts as two different platforms. This allows Shopify merchants and developers to use various front-end technologies like Shopify Hydrogen, Alokai (Formerly Vue Storefront), Nacelle, Fabric, Shogun, etc while still leveraging Shopify’s robust e-commerce capabilities, providing a unique and optimized user experience.
