Next.js development
Athryx Tech delivers Next.js development for companies that want a modern web stack without sacrificing production discipline. We build TypeScript applications with React and Next.js for product UIs, marketing sites that grow into products, and full-stack platforms for teams in Romania and internationally.
Next.js is a strong default when you need server rendering, API routes or route handlers, good SEO foundations, and a single codebase your team can maintain. We use it where it fits, and we are clear when a simpler static site or a different backend split is smarter.
Our day-to-day software work already runs on TypeScript, React, and Next.js for platforms and operational tools. That means patterns for auth, data fetching, forms, and deployment are proven in projects that have to stay up.
You get an application architecture, not a theme bolted onto a CMS by default. If content editing matters, we design that deliberately.
Problems we solve
- Legacy frontends that are slow to change and hard to hire for
- Separate marketing and product stacks that fight each other
- SEO and performance left as an afterthought
- Next.js demos that never get auth, data, or hosting right
Who this is for
- Product teams standardising on React and TypeScript
- Companies rebuilding marketing-plus-app experiences in one stack
- Startups shipping a web MVP with a path to scale
- Engineering leads who want clean App Router / Next.js structure

Frequently asked questions
Why Next.js instead of plain React?
Next.js gives you routing, rendering options, and deployment conventions that suit production apps. Plain React is fine for some SPAs; we recommend Next.js when SEO, server rendering, or full-stack delivery matters.
Do you use the App Router?
Yes, for new projects we typically use the App Router with TypeScript. We can also maintain or extend Pages Router codebases when that is what you already run.
Can you migrate an existing site to Next.js?
Yes, in phases. We migrate high-value routes first so you are not stuck in a long rewrite with no releases.
Will you hand over the codebase?
Always. You own the code. We structure repositories so your team or another partner can continue after our engagement.
