Hyvä vs Luma 2026: performance, ROI, migration
TL;DR — In 2026 Hyvä is the de facto standard for every new Magento project. Luma remains on legacy shops but loses every performance discussion. Luma → Hyvä migration is worth it in 90% of cases with ROI < 12 months thanks to better mobile conversion and lower maintenance costs.

FAQ
How much does a Hyvä migration really cost?
Between €30k and €350k. Median €60-80k for typical B2C with 500-1,000 SKUs.
How long does a Hyvä migration take?
2-4 months for mid B2C, 5-8 months for B2B with custom checkout.
Is the Hyvä license really one-off?
Yes, ~€1,000 once per domain. No recurring fees.
Are my Luma extensions compatible with Hyvä?
Check hyva-themes.com/compatibility. Major vendors (Amasty, Mageplaza, MageWorx) offer official compatibility.
Will I lose SEO in the migration?
No if done correctly: URLs unchanged, meta identical, JSON-LD equivalent. In practice SEO improves thanks to CWV.
Does my team need new skills?
Yes: Alpine.js + Tailwind instead of KnockoutJS + LESS. 1-2 weeks onboarding for experienced frontend devs.

Does Hyvä actually improve conversion rate?
Hyvä doesn't change the funnel: it improves Core Web Vitals (mobile LCP typically drops from 3-4s to under 1.5s). The conversion effect follows from that and, across the projects we run, lands between +8% and +25% on mobile — stronger on large catalogues and paid traffic. Measure it with a pre/post GA4 test rather than trusting a promise.
Is Hyvä compatible with Google Tag Manager and server-side tracking?
Yes. Hyvä exposes the standard Magento dataLayer and the GTM modules for Hyvä are mature; server-side tracking (Meta CAPI, GA4 Measurement Protocol, Google Ads Enhanced Conversions) is theme-independent. During migration the event mapping must be rebuilt, because checkout DOM selectors change.
Does Hyvä support Adobe Commerce B2B features?
Yes — dedicated Hyvä modules cover company accounts, customer price lists, requisition lists and B2B checkout. Heavy B2B customisations built on Luma have to be rewritten in Alpine.js/Tailwind, and that is usually the largest line in a migration quote.
How do I know whether to migrate now?
Three numbers decide it: current mobile LCP, share of revenue from mobile, and yearly Luma theme maintenance cost. If LCP is above 2.5s and mobile is over 50% of revenue, the migration typically pays back within 12-18 months. Armah runs the maths in a free 30-minute audit: book the audit.
