Next.js Development Company India —
Apps That Load in Under 1s
We build production-grade Next.js applications — SaaS platforms, headless ecommerce, marketing sites, and dashboards. App Router, React Server Components, TypeScript throughout. 40+ projects delivered.
How We Approach Next.js Development
The difference between a working Next.js app and a great one is in the decisions you make before writing the first component.
App Router Native — Not Playing Catch-Up
We've been building with Next.js App Router since its stable release. React Server Components, streaming with Suspense, parallel routes, intercepting routes, Server Actions — we use these properly, not as workarounds. Your codebase won't be a mix of Pages Router patterns bolted onto App Router.
TypeScript on Every Project — No Exceptions
Every Next.js project we deliver is TypeScript throughout — pages, components, API routes, server actions, and utility functions. This isn't optional. Typed code catches bugs at compile time, makes onboarding faster, and keeps large codebases maintainable as your team grows.
Performance Is Architecture, Not Afterthought
Getting 95+ Lighthouse isn't luck — it's the result of thinking about performance at the architecture stage: what to server-render vs client-render, how to structure data fetching, where to put caching, how to handle fonts and images. We make these decisions before writing a component, not after launch.
We Write Code You Can Hand to Your Team
We follow the same conventions we'd want to inherit: consistent folder structure, named exports, co-located tests, and documented decisions via ADRs (Architecture Decision Records). When your internal team takes over, they won't need us to explain the codebase.
Next.js Development Services
From SaaS platforms to headless storefronts — we build it all in Next.js.
Next.js App Router Development
Production-grade Next.js 15 apps using App Router, React Server Components, and streaming. We design component trees that minimise client-side JavaScript — using Server Components for data fetching and Client Components only where interactivity is genuinely needed. Result: faster initial loads and better Core Web Vitals without sacrificing user experience.
Headless CMS Integration
We connect Next.js to Sanity, Contentful, Prismic, or Strapi for content-driven sites — marketing pages, blogs, documentation, and landing pages. Editors get a real CMS with visual editing; the site gets statically generated HTML with ISR for instant page loads. We handle schema design, content modelling, and preview mode setup.
SaaS Platform Development
Full-stack SaaS applications built on Next.js with Supabase (auth + database + storage), Stripe billing, team management, multi-tenancy, and role-based access control. We've delivered SaaS platforms in 8 weeks — from spec to production with a working subscription flow. See our SaaS development page for more.
SaaS development →Next.js Ecommerce Development
Headless Shopify or WooCommerce storefronts powered by Next.js — Shopify Storefront API (GraphQL) or WooCommerce REST API as the backend, Next.js as the presentation layer. The result: an ecommerce experience with full Next.js performance — 90+ PageSpeed, edge caching, and SEO-friendly SSR on product and collection pages.
Headless ecommerce →Next.js API & Backend Development
API Routes, Route Handlers, Server Actions, and tRPC — we build type-safe backends within Next.js or as standalone Node.js services. Typical stack: Supabase or Neon (PostgreSQL), Prisma ORM, Zod for validation, and Uploadthing or AWS S3 for file storage. Everything is typed end-to-end from database schema to UI component.
Legacy Replatforming to Next.js
We migrate legacy Angular, CRA (Create React App), PHP, or static sites to Next.js using an incremental strategy — one route at a time, behind the same domain, with zero downtime. This lets your old app run while the new one is being built, validated, and rolled out — no big-bang rewrite risk.
Next.js vs React vs PHP vs Vue
Why we recommend Next.js for production web applications, and when other options make sense.
| Feature | Next.js ✦ | React CRA | PHP / WP | Vue / Nuxt |
|---|---|---|---|---|
| Server-side rendering | ✓ RSC + SSR + SSG | ✗ Client only (CRA) | ✓ Yes (but no JS app) | ✓ Nuxt.js |
| SEO out of the box | ✓ Excellent | ✗ Requires extra setup | ✓ Yes | ✓ With Nuxt.js |
| TypeScript support | ✓ First-class | ✓ Supported | Partial (typed hints) | ✓ Supported |
| API routes / backend | ✓ Built-in (Route Handlers) | ✗ Need separate backend | ✓ Native | ✓ Nuxt server routes |
| Edge / CDN caching | ✓ Native ISR + edge | ✗ Manual setup | ✗ Complex to implement | ✓ With Nuxt |
| Image optimisation | ✓ Built-in (next/image) | ✗ Manual | ✗ Manual | Partial (nuxt/image) |
| Ecosystem maturity | ✓ Largest React framework | ✓ Largest JS library | ✓ Massive | Growing |
| Best for | Prod web apps, SaaS, ecommerce | SPAs (not public-facing) | CMS (WordPress) | Lighter apps, Europe market |
✦ We recommend Next.js for almost all production web apps. We'll tell you honestly if another framework fits your use case better.
How We Build Your Next.js Project
A structured, agile process — weekly demos, no surprises, clean handover.
Technical Discovery & Architecture
We start by mapping your data models, user flows, auth requirements, and integrations. Output is a written Architecture Decision Record — what we're building, how it's structured, which packages we're using and why, and how it'll scale. You see the plan before a single component is written.
UI/UX Design in Figma
Complete Figma designs: all key screens, component library, responsive breakpoints (mobile, tablet, desktop), loading states, error states, and empty states. We design the interaction model too — not just how it looks, but how it behaves. You approve designs before dev starts.
Sprint-Based Development
We build in 1-week sprints with weekly demos on a live staging URL. TypeScript throughout, ESLint + Prettier enforced, unit tests for business logic (Vitest), and E2E tests for critical flows (Playwright). Code reviews on every PR. You can see progress every week.
Integration & QA
Third-party API integrations (Stripe, Supabase, CMS, etc.) tested end-to-end including failure and edge cases. Cross-browser QA on Chrome, Safari, Firefox, and Edge. Performance audit with Lighthouse and WebPageTest before launch.
Deployment & Handover
CI/CD pipeline on GitHub Actions, deployment to Vercel (preferred) or AWS. Environment variables documented. Monitoring set up (Sentry, Uptime Robot). Full handover: recorded codebase walkthrough, ADR docs, and README with setup instructions. 30 days post-launch support included.
Our Standard Next.js Stack
What Our Next.js Clients Say
"Sigill rebuilt our SaaS dashboard in Next.js from a legacy Angular codebase. Load time dropped from 6s to under 1s. The TypeScript codebase is clean and our team could onboard in days, not weeks. Excellent execution."
"We went from idea to a fully working SaaS MVP with Stripe billing and team invites in 7 weeks. The App Router architecture they chose means we can add features without slowing the app down. Exactly what we needed."
"Our headless Shopify frontend now scores 97 on Lighthouse. The Next.js storefront is dramatically faster than our previous Shopify theme. Conversion rate is up 1.4% which on our volume is significant."
Frequently Asked Questions
Everything you need to know about our Next.js development services.
A marketing website or landing page in Next.js typically costs ₹40,000–₹1,20,000 depending on number of pages and design complexity. A full-stack SaaS application or ecommerce platform costs ₹1,50,000–₹5,00,000+ depending on features, integrations, and auth complexity. We provide a fixed-price quote after a technical discovery call.
CRA produces a single-page application — no server-side rendering, no built-in routing, and poor SEO by default. Next.js gives you server-side rendering, static generation, image optimisation, built-in routing, API routes, and edge caching out of the box. For any production web application that needs to rank on Google or load fast for real users, Next.js is almost always the better choice.
We use the App Router (Next.js 13+) for all new projects — it enables React Server Components, streaming with Suspense, parallel routes, and more granular caching control. For existing Pages Router codebases, we maintain and extend them, and can incrementally migrate routes to App Router if that's the right move.
Supabase (PostgreSQL) is our default for most projects — it gives you a managed database, real-time subscriptions, row-level security, auth, and storage in one platform. For larger projects, we use Neon or PlanetScale with Prisma or Drizzle ORM. For read-heavy CMS-driven sites, we use a headless CMS (Sanity or Contentful) as the data layer.
Vercel is our first choice — built by the Next.js team, it handles ISR, edge functions, preview deployments, and zero-config CI/CD. For clients who need to stay on AWS, we deploy to AWS Amplify or EC2 with CloudFront. For static exports, we deploy to cPanel or any hosting that serves static files.
Yes — SaaS is one of our primary use cases for Next.js. We build full-stack SaaS platforms with auth (Clerk or NextAuth), Stripe billing (subscriptions, usage-based, one-time), team management, multi-tenancy, and role-based access. Our typical SaaS MVP timeline is 6–8 weeks to a working product with payments.
Yes. We migrate from React CRA, Angular, Vue, and even PHP/WordPress-fronted sites to Next.js. Our approach is incremental — we migrate one route at a time behind the same domain, which means zero downtime and the ability to validate each section before decommissioning the old code.
Absolutely. A headless Next.js frontend over Shopify (Storefront API) or WooCommerce (REST API) gives you the best of both worlds — Shopify or WooCommerce handles the commerce backend (products, cart, checkout, payments), and Next.js delivers a lightning-fast, SEO-optimised storefront. Our headless stores consistently score 90+ on PageSpeed.
Yes — Next.js is one of the best frameworks for SEO. Server-rendered HTML is crawlable by Googlebot immediately (no JavaScript rendering required). The Metadata API makes it easy to generate dynamic meta tags, Open Graph images, and structured data. Combined with fast load times and Core Web Vitals compliance, Next.js-built sites typically rank faster and higher than SPA alternatives.
Yes. We write Vitest unit tests for business logic (utilities, data transformation, server actions) and Playwright E2E tests for critical user flows — auth, checkout, form submission, and key navigations. We also run Lighthouse audits and axe accessibility checks as part of our QA process. Code coverage targets are agreed in the project spec.
