The combination of Next.js and a headless CMS like Sanity creates websites that are fast for users, flexible for content editors, and maintainable for developers. Next.js 15 introduces new features that make this integration even more powerful.

Traditional CMS platforms like WordPress couple content and presentation. This creates limitations: themes restrict design, plugins cause conflicts, and scaling requires complex infrastructure. Headless CMS separates content from presentation, letting you use the best tools for each job.

Partial Prerendering combines static and dynamic content at the component level. Server Components reduce JavaScript sent to browsers. Improved Image and Font optimization. These features, combined with Vercel's edge network, deliver sub-second page loads globally.

Sanity provides real-time collaboration, structured content modeling, and a customizable studio. Content is delivered via a global CDN with <50ms response times. GROQ query language offers flexibility beyond GraphQL. The generous free tier covers most project needs.

Incremental Static Regeneration keeps pages fresh without rebuilding the entire site. Configure revalidation times per route. Use Sanity webhooks to trigger on-demand revalidation when content changes. This gives you the speed of static sites with the freshness of dynamic content.

The Next.js + Sanity stack powers re:fabrika.com and many client projects. The developer experience, content flexibility, and end-user performance make it our go-to architecture for modern websites.
