We build on the latest stable version of Next.js, currently using the App Router architecture introduced in Next.js 13 and refined through subsequent releases. The App Router provides React Server Components, streaming, and parallel route loading that significantly improve both performance and developer experience compared to the older Pages Router. For existing clients, we handle Next.js upgrades as part of our ongoing maintenance, carefully testing each upgrade against your specific codebase and integrations before deploying. We follow a progressive upgrade strategy — evaluating each new release for breaking changes, testing in a staging environment, and rolling out with monitoring in place. We do not upgrade for the sake of being on the latest version; each upgrade is justified by specific performance improvements, security patches, or feature capabilities that benefit your site.

Next.js provides the best SEO foundation of any React-based framework because of its flexible rendering strategies. Server-side rendering ensures search engine crawlers receive fully rendered HTML on the first request, eliminating the JavaScript rendering dependency that plagues client-side React applications. Static generation pre-builds pages at deploy time for maximum crawl efficiency. The built-in Metadata API provides a structured way to manage title tags, meta descriptions, Open Graph tags, and canonical URLs at both the layout and page level. Dynamic sitemap generation, robots.txt configuration, and JSON-LD structured data all have first-class support. At Pelstack, we leverage these capabilities to build sites that consistently achieve green Core Web Vitals scores and strong search visibility. Our architecture uses ISR with tag-based revalidation so content updates trigger targeted page rebuilds rather than full site deployments.

Yes, website migration to Next.js is one of our most common engagement types. We have migrated sites from WordPress, Gatsby, Webflow, HubSpot CMS, custom PHP applications, and older React frameworks. The migration process follows a structured approach: first we audit your current site to document all pages, URLs, functionality, and integrations that need to be preserved. Then we design the Next.js architecture including routing structure, component hierarchy, and data fetching patterns. We build the new site in a parallel environment while your current site continues operating normally. Before launch, we create comprehensive redirect maps, validate SEO parity, and run performance benchmarks. Post-migration, we monitor search performance and user behavior closely for four to six weeks to catch any issues early. Most migrations result in immediate performance improvements and better Core Web Vitals scores because of Next.js's built-in optimizations.

The investment for a Next.js development engagement depends on the scope of your project — whether it is a full website build with design, a migration from another framework, or ongoing development on an existing Next.js site. A typical B2B marketing website build with Pelstack includes strategy, design system creation, CMS integration, and performance optimization over a ten to sixteen week engagement. What matters more than the initial investment is the return: our Next.js builds consistently achieve sub-second load times, green Core Web Vitals scores, and measurable improvements in organic search visibility that generate pipeline value far exceeding the cost. We scope every engagement based on your specific requirements rather than offering one-size-fits-all packages. Many clients continue with an ongoing retainer after launch for optimization, new page development, and A/B testing that compounds the value of the initial build over time.
