What We Build
End-to-End Next.js Engineering
From App Router architecture to production deployment — we cover every layer of modern Next.js development your product needs to perform and scale.
Edge Delivery
Edge & CDN Delivery
Global edge delivery with Vercel Edge Network, Cloudflare, or AWS CloudFront. Sub-100ms TTFB worldwide for every user, everywhere.
TypeScript
Strict TypeScript Architecture
Fully typed Next.js codebases with strict TypeScript, Zod validation schemas, and end-to-end type safety from API routes to UI components.
Authentication
Authentication Systems
NextAuth v5 integration with OAuth 2.0, JWT sessions, RBAC, and secure cookie management. Production-grade security from the first commit.
API & Backend
API Routes & Server Actions
Server actions, API routes, and optional tRPC integration built directly on Next.js — no separate backend needed for most SaaS products.
Deployment
Production Deployment
Dockerised deployments, Nginx reverse proxy, CI/CD pipelines, and zero-downtime releases on AWS, GCP, or Vercel — infrastructure you own.

FAQ
Frequently asked questions
Everything you need to know about Next.js development, SSR vs ISR, migrations, and how we work.
- Why use Next.js for SaaS in 2026?
- Next.js is the leading React framework for production SaaS because it combines server-side rendering (SSR), incremental static regeneration (ISR), server actions, and edge deployment in a single, well-supported framework. For SaaS products, this means faster page loads, better SEO, lower server costs, and a codebase that can scale from 100 users to 1 million without a full rewrite.
- What is the difference between SSR, ISR, and CSR in Next.js?
- Server-Side Rendering (SSR) generates each page on the server at request time — ideal for pages requiring fresh data like dashboards. Incremental Static Regeneration (ISR) generates pages statically and revalidates them in the background — ideal for marketing pages. Client-Side Rendering (CSR) renders entirely in the browser — fine for authenticated app sections but poor for SEO. We choose the right strategy per route, not globally.
- Can you migrate our existing React app to Next.js?
- Yes. Migration from a CRA, Vite, or custom webpack React app to Next.js is one of the most common engagements we handle. We assess the existing codebase first, identify routing, data-fetching, and state management patterns, then plan a phased migration that keeps your product live throughout. Most migrations complete in 4–8 weeks depending on codebase size.
- Do you handle Next.js deployment and DevOps?
- Yes — we handle the full stack from code to production. Our Production Deployment service covers Docker containerisation, Nginx configuration, SSL termination, CI/CD pipelines (GitHub Actions or GitLab CI), zero-downtime deployments, and server hardening on your cloud of choice (AWS, GCP, DigitalOcean, or Vercel). You own the infrastructure; we set it up correctly.
- How do you ensure Core Web Vitals compliance?
- We build for Core Web Vitals from day one — not as a post-launch fix. This means: preloading the LCP hero image with next/image and priority={true}, using Server Components to reduce client-side JavaScript, implementing correct ISR strategies to avoid CLS from layout shifts, auditing third-party scripts, and running Lighthouse CI in the deployment pipeline to catch regressions before they reach users.
- What is the difference between App Router and Pages Router?
- Next.js App Router (introduced in Next.js 13, stable from 14+) uses React Server Components, nested layouts, and a new file-based routing convention. It is the recommended approach for new projects and enables features like streaming, Suspense, and server actions. Pages Router is the legacy system — still supported but not recommended for new builds. All Aurayan projects use App Router.
