Services

Custom Next.js development services

Not promises. Results.

Headless e-commerce with Next.js

We connect Next.js to Shopify, a CMS or a commerce API to create a fast mobile experience while keeping product pages and content manageable.

Next.js audits, redesigns and migrations

We audit an existing Next.js project or migrate a React SPA, PHP website or another framework. The plan covers URLs, JavaScript, SEO, LCP and deployment.

Next.js applications and SaaS development

A Next.js application can combine a React interface, server logic, authentication and APIs in one TypeScript codebase. We adapt the App Router, Server Components, streaming and Supabase to the product.

Websites built with Next.js

We build corporate websites, blogs and marketing pages with Next.js. Static generation, ISR, images and content are configured for SEO, Core Web Vitals and simple updates.

Planning a Next.js project?

Website, SaaS platform or business application: let’s scope users, content and the Next.js stack before development.

Objective

Why choose Next.js for your web project?

1

A complete React framework

Next.js adds routing, server rendering, static generation, APIs and image optimization to React. This foundation reduces the number of tools required for a modern web application.

2

SSR, SSG and ISR for each page

Next.js lets each page use dynamic SSR, pre-rendered SSG or ISR. The choice depends on content, update frequency, traffic and SEO goals.

3

App Router and Server Components

React Server Components reduce the JavaScript sent to users and move data requests closer to the server. Interactive components remain client-side where needed.

4

Vercel or your own infrastructure

Next.js integrates naturally with Vercel for previews and fast deployments. We can also prepare Docker-based hosting with caching, monitoring and a controlled production process.

Maintenance

Performance, SEO and rendering with Next.js

A fast Next.js project requires measured decisions about rendering, caching, images and the code running in the browser and on the server.

Core Web Vitals and Lighthouse

We measure LCP, visual stability and interaction speed. Next.js image, font and JavaScript optimization focuses on the pages that matter.

Caching and dynamic data

Data Cache, Full Route Cache and Router Cache serve different purposes. We document their roles and revalidation rules to prevent stale content.

Quality and production

TypeScript, tests, Vercel previews and error monitoring make delivery safer. Next.js updates are checked before production deployment.

Interfaces

Which ecosystem should support Next.js?

Headless CMS and content

Next.js connects to Directus, Sanity or WordPress for editorial websites, blogs and marketing pages managed by your team.

Node.js APIs and databases

A full-stack application can use Next.js Route Handlers or connect to a Node.js API, CRM and PostgreSQL database.

Vercel, Docker and monitoring

A Next.js project can run on Vercel or your infrastructure. We adapt previews, logs, alerts and the scaling strategy.
