Shopify Hydrogen

React-based headless commerce framework for building custom storefronts with full design control. Built on Remix and engineered for performance and productivity: server-side rendering reduces client JavaScript, while optimistic UI and nested routes keep interactions fast and smooth.

Trusted by brands such as TOMS, Lady Gaga, Denim Tears, Atoms, and Chubbies. Stands out by combining the Remix stack with commerce-optimized tooling: pre-built routes for products, collections, cart, and account, plus Mock.shop for development without a Shopify login. Fully open source.

Key features:

• React and Remix stack with flexible UI components for commerce
• Server-side rendering with minimal client-side JavaScript
• Optimistic UI and nested routes for instant feedback and smooth transitions
• Built-in multi-market support: subfolders, subdomains, or custom domains
• Deploy to Oxygen or run on any Node or edge runtime

Engineers use Hydrogen when they need a custom storefront backed by Shopify's catalog and checkout but want to own the front-end stack. Fits teams already using React or Remix who integrate with CMS like Sanity or Contentful, analytics like Amplitude, and commerce extensions.
