Will Hyvä fully replace Luma?

For new builds: yes, effectively already happening. Hyvä (Tailwind + Alpine) is what AI codegen writes best, what produces Lighthouse 95+ out of the box, and what new agencies default to. By 2027, “new Magento build” will mean “Hyvä build” in 90%+ of cases. For existing Luma stores: not necessarily, the ROI doesn’t pencil for a healthy revenue Luma store to migrate just because Hyvä is faster. Luma stays in production through 2030 and beyond, but stops being the choice for greenfield work. Adobe doesn’t kill Luma; the market does, with AI codegen accelerating the trend.
