The full answer
Next.js lets each page use the rendering strategy that suits it. Marketing pages and blog content can be generated ahead of time and served from a CDN, product pages can render on the server with fresh data, and logged-in areas can behave like a desktop application.
That flexibility is why Creuto uses it for very different products: SEO-driven websites on a headless CMS, multi-tenant SaaS platforms, B2B marketplaces and internal tools with complex forms and tables.
Creuto pairs Next.js with a typed API layer, usually NestJS or FastAPI, and a PostgreSQL database. Authentication, role-based access control, form validation, error tracking and analytics are set up in the first sprints rather than added later.
Performance and accessibility are built in: image optimisation, code splitting, Core Web Vitals monitoring and semantic markup that screen readers and search engines can both understand.
Next.js is also what the Creuto website itself runs on, so the team keeps current, practical knowledge of the framework. If you have an existing React application, Creuto can migrate it to Next.js incrementally rather than rewriting it.
