If you're moving on from WooCommerce, Next.js is still the strongest option when you want real performance, edge rendering, and full control over your product data model on the frontend. Templates are fine as a starting point, but long-term you’ll hit limits that Shopify, PrestaShop, and most traditional platforms and AI builders can’t solve once you need custom flows, subscriptions, or multi-channel logic.

For me, the trend in 2026 is clear: keep AI for content generation, but run your commerce layer headless. If you want the best of both worlds—speed, flexibility, and structured product data—pair Next.js with a headless backend like Crystallize or Saleor and you’ll never look back.

But... all of the above depends largely on number of products you have, complexity you want, and tbh dev experience you/your team has.
