Build lightning-fast Magento stores with the modern Hyvä framework. Alpine.js and Tailwind CSS replace the legacy Luma frontend, delivering dramatically faster page loads, better Core Web Vitals, and a superior developer experience.
Hyvä is a modern replacement for Magento's default Luma and Blank themes. It strips out the heavy RequireJS and KnockoutJS frontend stack and replaces it with lightweight Alpine.js for reactivity and Tailwind CSS for styling.
The result is dramatically faster page loads, significantly better Core Web Vitals scores, and a vastly improved developer experience. Hyvä themes typically achieve 90+ Lighthouse scores out of the box, compared to Luma's struggle to break 30.
For merchants, this means faster stores, better SEO rankings, higher conversion rates, and lower development costs. For developers, it means working with a modern, enjoyable tech stack instead of wrestling with Magento's legacy frontend architecture.
Key Benefits
90% less JavaScript than Luma
Alpine.js reactivity for dynamic interactions
Tailwind CSS utility classes for rapid styling
Faster development cycles and lower costs
Better SEO performance through Core Web Vitals
Hyvä vs Luma vs PWA
Luma (Default)
Familiar but heavy. Built on RequireJS and KnockoutJS, Luma delivers poor Core Web Vitals scores, ships large JavaScript bundles, and slows down development with its complex, outdated frontend architecture.
Hyvä
Modern and lightweight. Built on Alpine.js and Tailwind CSS, Hyvä delivers excellent Core Web Vitals, ships 90% less JavaScript, enables rapid development, and benefits from a growing ecosystem of compatible modules.
PWA Studio
Headless and decoupled. React-based with complex infrastructure requirements, PWA Studio comes with higher development costs, limited extension compatibility, and a steeper learning curve for Magento teams.
Core Web Vitals Impact
LCP
Largest Contentful Paint under 2.5s with optimised asset loading, minimal render-blocking resources, and efficient image delivery.
FID / INP
First Input Delay near zero with lightweight Alpine.js interactions that keep the main thread free and responsive to user input.
CLS
Cumulative Layout Shift minimised with proper image and font loading strategies, explicit dimensions, and optimised above-the-fold rendering.
Conversion Impact
Every 100ms improvement in load time increases conversions by up to 1%. Hyvä's performance gains translate directly into revenue growth.
