Monolith strengths
Theme-based stores launch quickly and keep merchandising simple. They fit early catalogues when differentiation is not yet a performance problem.
When headless wins
Choose headless when Core Web Vitals, custom checkout or unique UX become revenue-critical. NexaPhaze builds Hydrogen and Next.js Commerce storefronts for those moments.
Migration reality
Plan redirects, peak traffic and SEO continuity. A beautiful cutover that drops organic rankings is a failed launch — architecture and content ops must move together.
