VT Netzwelt Next.js Excellence
Somebody at your company will inherit this Next.js codebase, and they are not in the room at kickoff. We build and document for that person, which is why our clients' teams keep shipping after we hand over.
We build Next.js applications, move teams onto it from whatever they are running now, and keep the result fast once
it is carrying real load.
We build on the App Router with Server Components, and TypeScript goes in from the first commit. How each route renders and caches gets decided against your traffic, not left to whatever the default is.
Not everyone can run on Vercel. We deploy Next.js on AWS or Azure with caching, image optimization and revalidation working properly, which is the part teams tend to discover is missing after they have already moved.
Next.js front ends on Strapi, DatoCMS, Contentful or whatever runs your catalogue. Set up with ISR and on-demand revalidation, so your editors can publish without waiting for a deploy.
Authorization in Next.js has been bypassed at the framework level more than once, both times because the check sat in the proxy layer. We look at where yours runs and move it to the data layer where it belongs.
Senior engineers who join your team, work in your repository and report to your product owner. For a sprint or for a year, whichever the roadmap needs.
Choose static, server-side, or hybrid rendering where it fits — balancing performance, SEO, and data needs with precision.
Automatic code splitting, image optimization, and efficient asset delivery reduce manual tuning and keep applications fast at scale.
Seamless deployment to edge runtimes and CDNs ensures low-latency performance for users worldwide.
Update static pages on demand without full redeploys — essential for sites with frequently changing data.
First-class React support, API routes, and strong tooling reduce boilerplate, letting teams build faster and maintain cleaner codebases.

FAQs
Building web applications that need to load fast and rank in search. Marketing sites, dashboards, e-commerce storefronts, SaaS products. It renders on the server so pages arrive complete, which is why teams pick it when SEO and speed both matter.
Scope sets the cost, not the framework. A marketing site sits well below a multi-tenant SaaS platform with auth, billing and a dashboard. We run a short business analysis phase, then commit to scope, timeline and a fixed price before development starts, so the number is known before you spend.
Yes, and it’s one of the main reasons to choose it. Server-side rendering and static generation mean search engines get complete HTML rather than a blank shell waiting on JavaScript. Paired with Core Web Vitals work, that is the combination that moves rankings.
React is the library Next.js is built on. React alone gives you the components; Next.js adds routing, server rendering, caching and the build pipeline around them. If you are choosing between them, you are really choosing between assembling those pieces yourself or starting with them included. Our React.js development page covers the library on its own.
The App Router, for anything new. It’s where Server Components, streaming and Cache Components live, and it’s the model Vercel is actively developing. The Pages Router still works and we maintain plenty of it, but starting a 2026 build there means opting out of the framework’s direction. We also finish half-migrated apps stuck between the two.
Yes, and it’s common work. We keep your content, move it to a headless CMS such as Sanity or Strapi, and rebuild the frontend on Next.js so the site gets faster without losing its search rankings. It runs in stages, so nothing goes offline mid-move.
It’s built for them. Server Components keep large applications fast, TypeScript holds the boundaries between teams, and the security model supports proper authorization when it’s implemented at the data layer. Our ISO 27001 certification exists for exactly this kind of build.
One call could save you an expensive Next.js rewrite.
