Next.js Development

Web applications and customer portals with Next.js – fast, search-friendly and hosted where you need it.

dectria builds web applications, customer portals and SaaS platforms with Next.js. We work with the App Router, React Server Components and Server Actions, and we use TypeScript throughout – from the frontend to the API.

We use Next.js in client projects and in our own products. That is why we know the framework's strengths and its limits: caching, deployment outside Vercel, and the split between server and client components.

We host where it fits your project: on Vercel, on Cloudflare or on your own servers in the EU. We make that decision together, based on data protection, operating effort and cost.

What is Next.js – and when is it worth it?

Next.js is a React-based framework that renders pages on the server, pre-generates them statically, or combines both. This way, applications load fast and are readable for search engines while staying interactive.

It is worth it for applications with logic, login and data – portals, dashboards, SaaS products – that also need to load fast and be found. It is not worth it for pure content websites without app logic: a static generator such as Astro is leaner there. And switching only for the technology rarely pays off if your team already works deeply in another framework.

Next.js or Astro?

	Next.js	Astro
Rendering	server, static or mixed, chosen per page	static by default, server rendering optional
JavaScript in the browser	React runtime on every page	only for interactive parts (islands)
Strength	applications with login, data and interaction	content websites, blogs, documentation
Typical uses	customer portals, dashboards, SaaS products	company websites – dectria.com also runs on Astro

What We Build with Next.js

Use Cases

Typical Use Cases

SaaS Platforms & Dashboards

Web applications with server-side rendering and role-based access control, in which users capture, analyze and approve data.

Customer Portals & Self-Service

Portals with login, document storage and automated workflows, through which your customers and partners handle requests themselves.

Websites with a Headless CMS

Content-driven websites where editors work in the CMS and Next.js delivers the pages fast and search-friendly.

FAQ

Next.js FAQ

Why does dectria use Next.js?

Because Next.js combines server-side rendering, static pages and API logic in one project. For many applications this saves a separate backend layer, gives good load times and stays maintainable for other teams thanks to React. For pure content websites, we often recommend Astro instead.

What about hosting and data protection in the EU?

Next.js does not only run on Vercel. Vercel is a US company and is subject to US law, even when it uses European data centers. Where that matters to you, we run Next.js on your own servers in the EU or on Cloudflare. We decide with you which option fits, based on data protection, operating effort and cost.

Does dectria also handle operations?

Yes. We set up CI/CD pipelines, containers and monitoring, and on request we take care of updates and operations. When self-hosting, we configure caching so that it works reliably without Vercel's infrastructure.

Can we hand over an existing Next.js application to dectria?

Yes. We first review the code, dependencies and deployment and show where technical debt sits. Then we develop the application further – we also plan moves from the Pages Router to the App Router step by step, without interrupting operations.
