When the framework decides for you
Next.js handles routing, rendering, and API layers out of the box. The problem is that defaults don’t account for your traffic patterns, SEO requirements, or deployment constraints. A page that should be static ships with SSR. An API route replaces what should be a server action. Curotec configures Next.js so every architectural choice is intentional, not inherited.
Our capabilities include:
- Rendering strategy per route (SSR, SSG, ISR, CSR)
- App router and server component architecture
- API route and server action configuration
- Image, font, and script optimization
- Deployment on Vercel, self-hosted, or containerized infrastructure
- Migration from pages router or Create React App
Who we support
We build Next.js applications for teams shipping customer-facing products where page speed, SEO rankings, and deployment flexibility directly affect revenue.
SaaS Teams Building on Next.js
Your product runs on Next.js but rendering decisions were never deliberate. Pages load slowly because SSR runs where static would be faster, and client-rendered content doesn't get indexed. You need each route matched to the right rendering strategy.
Teams Migrating to the App Router
You're still on the pages router or Create React App and the migration path feels risky. Server components, new data fetching patterns, and changed routing conventions mean a rewrite, not a drop-in upgrade. You need engineers who've handled the transition without breaking production.
Engineering Leads Deploying Off Vercel
Your organization requires self-hosted or containerized deployment, but Next.js is optimized for Vercel by default. You need build pipelines, caching layers, and image optimization configured for AWS, Docker, or Kubernetes without losing framework features.

Tools and technologies in our Next.js projects
Next.js Core & Configuration
Curotec configures the framework internals that control how your app renders, routes, and serves content across environments.
- App Router – File-system routing with nested layouts, loading states, error boundaries, and parallel route support for complex navigation patterns
- Server Components – React components that execute on the server, reducing client-side JavaScript and improving initial page load performance
- next.config.js – Central configuration for redirects, rewrites, environment variables, image domains, and build-time feature flags
- Middleware – Edge-executed logic that runs before requests resolve, handling auth checks, geolocation redirects, and A/B routing at the network layer
- Turbopack – Rust-based bundler that replaces Webpack for local development with faster cold starts and incremental compilation
- TypeScript – First-class type support with auto-generated types for route params, API handlers, and data fetching functions
Rendering & Data Fetching
How each page loads and indexes depends on which strategy you assign per route and how data flows between server and client.
- Server-Side Rendering (SSR) – Generates HTML on every request for pages with dynamic, user-specific, or frequently changing content
- Static Site Generation (SSG) – Pre-builds pages at compile time for content that rarely changes, delivering near-instant load times from a CDN
- Incremental Static Regeneration (ISR) – Revalidates static pages on a configurable interval so content stays fresh without full rebuilds
- Client-Side Rendering (CSR) – Defers content loading to the browser for interactive components that don’t need SEO indexing or initial paint speed
- Server Actions – Execute mutations directly from components without writing API endpoints, reducing boilerplate for form submissions and data updates
- Route Handlers – API endpoints defined alongside your pages for webhooks, third-party integrations, and backend logic within the same codebase
Styling & UI Components
Your frontend stack determines how quickly your team builds and maintains consistent interfaces across the application.
- Tailwind CSS – Utility-first framework with tree-shaking that keeps production CSS minimal regardless of how many classes your components reference
- CSS Modules – Scoped stylesheets that prevent class name collisions across components without runtime overhead or JavaScript dependencies
- shadcn/ui – Copy-paste component library built on Radix primitives with full customization control and no external package lock-in
- Radix UI – Unstyled, accessible primitives for modals, dropdowns, tabs, and other interactive patterns that meet WCAG standards
- next/image – Built-in image component with lazy loading, responsive sizing, format conversion, and CDN caching that improves Core Web Vitals
- next/font – Self-hosted font loading with zero layout shift, automatic subsetting, and preloading configured at the framework level
Authentication & Authorization
Protecting routes and managing sessions across server and client boundaries requires auth logic wired into the framework’s own lifecycle.
- NextAuth.js (Auth.js) – OAuth, credentials, and magic link providers with session management, JWT handling, and database-backed accounts
- Clerk – Drop-in auth with pre-built UI components, multi-factor support, and organization management for SaaS applications
- Middleware Auth – Route protection at the edge that validates tokens before the page renders, keeping unauthorized users from loading protected content
- Role-Based Access – Permission checks in server components, route handlers, and middleware that control what each user type can view or modify
- Session Strategies – JWT or database-backed sessions with configurable expiration, refresh logic, and secure cookie settings per environment
- CSRF & Security Headers – Cross-site request forgery protection and response headers configured through middleware and next.config.js
Testing & Quality Assurance
Catching broken layouts, failed API calls, and rendering mismatches before production requires tooling matched to the framework.
- Playwright – End-to-end browser specs that validate navigation, auth flows, and rendering across routes in Chromium, Firefox, and WebKit
- Jest – Unit and integration specs for server components, route handlers, and utility functions with built-in mocking and snapshot support
- React Testing Library – Component-level validation focused on user behavior rather than implementation details for maintainable coverage
- Cypress – Alternative E2E framework with visual debugging, time-travel snapshots, and component-level isolation for interactive UI flows
- Lighthouse CI – Automated Core Web Vitals auditing in your pipeline that flags performance regressions before they reach production
- GitHub Actions – CI workflows that run linting, type checks, specs, and Lighthouse audits on every pull request before merge
Deployment & Infrastructure
Where you host your Next.js app determines which features work natively and which need manual configuration to function correctly.
- Vercel – Zero-config deployment with automatic preview environments, edge functions, image optimization, and ISR support built into the platform
- AWS – Self-hosted deployment on EC2, ECS, or Lambda with CloudFront CDN, S3 static assets, and custom caching layers
- Docker – Containerized builds with multi-stage Dockerfiles that produce minimal production images for any hosting environment
- Kubernetes – Orchestrated deployments with horizontal pod autoscaling, readiness probes, and Helm charts for repeatable releases
- Terraform – Infrastructure-as-code provisioning for CDN distribution, load balancers, SSL certificates, and environment-specific configuration
- Datadog – APM tracing for server component execution, API route latency, and client-side performance metrics alongside infrastructure monitoring
FAQs about our Next.js development services
How is Next.js different from React?
React is a UI library. Next.js is a framework built on React that adds routing, rendering strategies, API routes, and deployment tooling. We use Next.js when your project needs SSR, SEO visibility, or full-stack capabilities beyond what React provides alone.
How do you choose a rendering strategy?
We audit each route based on content volatility, personalization needs, and SEO requirements. Static pages get SSG, dynamic pages get SSR, and frequently updated content uses ISR. No route should default to SSR without a reason.
Can you migrate us from the pages router?
Yes. We move routes incrementally to the app router so your application stays live throughout. Server components, new data fetching patterns, and layout nesting get introduced per section rather than in a single risky rewrite.
Do you deploy Next.js outside Vercel?
We deploy on AWS, Docker, and Kubernetes regularly. Self-hosted setups require manual configuration for image optimization, ISR, and caching that Vercel handles automatically. We build those layers so you keep framework features without platform lock-in.
How do you handle auth in Next.js?
We configure NextAuth or Clerk with middleware route protection, session management across server and client boundaries, and role-based access checks in server components and route handlers.
How do your engineers integrate with our team?
We work inside your repo, follow your branching conventions, and write code that matches your team’s patterns. The goal is a codebase your engineers own and extend after our engagement ends.
