Hyva Themes: Adobe Commerce Performance Without Compromise
Luma, the default Adobe Commerce frontend, is slow by design — it ships with jQuery, RequireJS, KnockoutJS, and a legacy LESS compile chain that produces bloated JavaScript bundles and consistently poor Core Web Vitals scores. For merchants competing on performance, Luma is a liability.
Hyva is the modern alternative — built on Alpine.js and Tailwind CSS with a fraction of Luma's JavaScript footprint. Hyva stores typically achieve Lighthouse mobile scores of 85-95 vs. Luma's 20-45. That gap translates directly into search ranking, paid media quality scores, and conversion rate.
We specialise in Hyva theme development and Luma-to-Hyva migrations. Every Hyva build we deliver is component-driven, fully tested, and optimised for Core Web Vitals at launch — not retrofitted after go-live. We handle complex third-party module compatibility, checkout customisation, and PWA-ready page architecture.
- Lighthouse mobile scores of 85-95 — consistently outperforming Luma builds
- Luma-to-Hyva migration with full third-party module compatibility assessment
- Component-driven architecture — maintainable, testable, extensible
- Core Web Vitals optimised at launch — not after client complaints

E-commerce PerformanceLuma-to-Hyva Migration for a High-Traffic Retailer
A retailer with 2.4M monthly sessions was on a heavily customised Luma theme. Mobile Lighthouse score was 22. Google Ads quality scores were falling, CPC was rising, and conversion rate on mobile was 1.1% against a desktop rate of 3.4%. The gap was costing £400K in monthly ad spend efficiency.
Full Luma-to-Hyva migration with custom Hyva theme development. All 14 third-party modules audited — 9 had native Hyva compatibility, 3 required custom Hyva adapters, 2 were replaced with lighter alternatives. Checkout preserved with all existing functionality.
- Mobile Lighthouse from 22 to 91 post-migration
- Mobile conversion rate from 1.1% to 2.3% within 30 days
- Google Ads quality scores improved — CPC reduced by an average 18%
New BuildHyva Theme for a New Adobe Commerce Launch
A DTC brand launching on Adobe Commerce wanted performance-first from day one — they had watched competitors launch on Luma and spend 12 months firefighting speed issues. They wanted a store that was fast on launch day, not optimised 6 months later.
Greenfield Adobe Commerce build on Hyva with a custom design system. All custom features — product configurator, size guide, lookbook, and bundled offers — built natively in Hyva without jQuery dependencies. Deployed on cloud infrastructure with full CDN and Varnish configuration.
- Lighthouse mobile score of 93 on launch day
- LCP under 1.8s on mobile from day one
- Zero performance regression tickets in the first 3 months
International ExpansionMulti-Market Hyva Rollout
An e-commerce group with Hyva stores in the UK wanted to replicate the performance across EU and APAC markets. The challenge was localisation — different languages, currencies, payment methods, and shipping providers per market — without forking the codebase.
Hyva multi-store architecture with a shared component library and locale-specific configuration layers. Translation management integrated with the Hyva theme. Market-specific payment modules (iDEAL, Klarna, Afterpay) added as Hyva-native modules without touching core theme files.
- All 4 new markets launched within 6 weeks each — using the shared component library
- Lighthouse scores within 3 points of the UK flagship across all markets
- Codebase maintenance reduced — one change propagates to all markets via shared components
