FAQ

More Hydrogen Questions.

Liquid is Shopify's traditional theme templating language. Themes render server-side from Liquid files, configured via Theme Editor. Hydrogen is React-based, fully custom storefronts built like a web app. Liquid wins on: time-to-launch (3-4 weeks vs 6-16 weeks), cost (theme ₹1.5-3.5L vs Hydrogen ₹8-25L), maintenance ease. Hydrogen wins on: performance (sub-1.5s LCP vs 2.5-3.5s on Liquid), UX customization depth, CMS integration, complex animations.
Use Hydrogen if: (1) Brand-defining UX is core to your strategy, (2) Core Web Vitals are critical (premium brand, paid search heavy), (3) Deep CMS integration needed (Sanity, Contentful for editorial commerce), (4) Custom PDP / complex variant configurators, (5) Multi-region with localized custom UX. Stick with themes if: time-to-market matters, budget is ₹3L or less, team can maintain Liquid, standard ecommerce UX is fine.
Simple Hydrogen build (6-8 weeks): ₹8-15L. Mid-complex Hydrogen with custom PDP, multi-region, advanced filtering (10-12 weeks): ₹15-22L. Complex Hydrogen with custom checkout flows, B2B layer, ERP integration (14-16 weeks): ₹22-30L+. Oxygen hosting is free with Shopify Plus. Most India D2C Hydrogen builds land at ₹12-18L.
No — Hydrogen works on all Shopify plans (Basic, Shopify, Advanced, Plus). Oxygen hosting is free only on Plus. On lower plans you can deploy Hydrogen to Vercel, Netlify, or AWS — just pay for hosting separately. For most enterprise Hydrogen builds, Plus is recommended because Oxygen + Plus B2B + checkout customization + 9 expansion stores together justify the upgrade.
