Trusted by clients across USA, UK, Canada and India.
A Next JS Development Company With a Live Next.js 15 Production Platform in Our Portfolio
Most businesses choosing Next.js face one of three challenges: their existing React SPA has poor Core Web Vitals and is losing Google rankings to server-rendered competitors; their eCommerce platform has slow product pages costing measurable conversion rate; or their Next.js web platform is live and working but there is no mobile app for users who want one.
We have built and shipped a live Next.js 15 production platform — Casavera (casavera.uk), a luxury hospitality booking platform for a UK client. Next.js 15, TypeScript, Tailwind CSS, GSAP animations, Leaflet maps, PostgreSQL, and Cloudflare edge deployment. 23 properties, SEO-optimised property pages, and booking flows — built at a fixed price with full source code ownership. Our mobile app development team builds the Flutter iOS and Android app on top of every Next.js API we deliver — same team, same architecture, same fixed-price model.
Every Next.js project uses the App Router, TypeScript strict mode, Tailwind CSS, Prisma or Drizzle ORM with PostgreSQL, NextAuth.js for authentication, and Vercel or Cloudflare for deployment. For AI-powered applications, we use Vercel AI SDK and OpenAI in Server Actions — AI processing server-side, API keys secure, AI features served to web and Flutter mobile from the same Next.js deployment. Core Web Vitals compliance — LCP under 2.5s, CLS under 0.1 — is measured at every sprint.
AZRIVA is an Ahmedabad-based Next.js development team working IST with daily overlap into UK mornings and USA afternoons. Every Next.js project is fixed price — pages, API routes, database, integrations, testing, and deployment — scoped completely before development begins. A mutual NDA is signed before any project discussion. Full source code transfers to you at handover.

What Our We Deliver Builds for You
End-to-end Next.js development — SEO-optimised web platforms, eCommerce, full-stack applications, and AI-powered Next.js backends. Fixed price. Full TypeScript source code ownership. Flutter mobile extension ready.
Next.js Development Tools We Work With
Every Next.js project is built with Next.js 15 App Router, TypeScript strict mode, and Tailwind CSS — deployed on Vercel or Cloudflare with Core Web Vitals compliance at every sprint. Full source code handed over at project completion.
Real Next.js Challenges.
Every project carries risks — poor UX, missed deadlines, underperforming results. Here is how we eliminate each one.
How We Deliver Next.js Projects
A six-stage delivery process designed for overseas clients — every sprint ends with a Vercel preview URL your entire team can test from any timezone. Every invoice is tied to a deliverable. The same discipline whether building your <a href="/mobile-app-development-company-india/" class="content-link">Next.js web platform or the Flutter mobile app</a> on top of it. No black-box development. No surprises at launch.
Discovery & Next.js Architecture
We begin with a structured discovery call to understand your Next.js project — rendering strategy (App Router SSR, SSG, or ISR), API routes architecture, database integration, authentication model, and deployment targets. We confirm Next.js 15 configuration, Tailwind CSS setup, and TypeScript strict mode before any development begins.
UI/UX Design & Data Fetching Strategy
Every Next.js page is designed in Figma and approved before development begins. Data fetching strategy per route is documented — which pages use SSR, which use SSG, which use ISR, and which API routes serve the Flutter mobile app. No surprises when rendering behaviour meets real user traffic.
Fixed-Price Proposal
A fixed-price proposal covers the complete Next.js scope — pages, components, API routes, database schema, third-party integrations, testing, and Vercel or Cloudflare deployment. One price. No hourly billing. No scope creep on agreed features.
Next.js TypeScript Development
Next.js development runs in two-week sprints using TypeScript with Next.js 15 App Router. Every sprint ends with a Vercel preview deployment — a shareable URL your entire team can test immediately across any device or timezone. Real progress, not status updates.
QA — Core Web Vitals and E2E Testing
Every Next.js build is tested with Jest and React Testing Library for component tests, Cypress for end-to-end tests, and Lighthouse for Core Web Vitals — LCP under 2.5s, CLS under 0.1, INP under 200ms. Cross-browser testing covers Chrome, Firefox, Safari, and Edge before every production deployment.
Deployment & Flutter Mobile Extension
We manage Next.js production deployment to Vercel or Cloudflare with edge caching and environment configuration. Post-launch support included for 60 days including Core Web Vitals monitoring. When your platform is ready for mobile users — we build the Flutter app on top of your existing Next.js API routes.
Industry-Specific Next.js Development
We deliver AI solutions for Next.js web applications across the industries where server-side rendering, edge performance, and SEO-first architecture drive organic traffic and conversion — retail, real estate, and travel.

Every Next.js project at AZRIVA is fixed price — scoped completely before development begins. Pricing depends on scope, number of pages and API routes, database complexity, and whether the project includes eCommerce or a Flutter mobile extension.
All pricing is fixed — the number in your proposal is the number on your invoice. Clients who extend their Next.js platform to Flutter mobile app development receive the same fixed-price model for the mobile project. VAT/GST applicable for Indian clients.
How We Engage With Businesses
Whether you need a fixed-price Next.js web platform, a dedicated full-stack team for ongoing development, or an AI-first Next.js architecture that powers both your web application and a Flutter mobile app from a single Vercel deployment.
Complete Next.js scope defined and priced before development begins — pages, API routes, database, integrations, testing, and deployment. One fixed price. Every sprint ends with a Vercel preview URL. The same model extends to Flutter mobile when your platform is ready.
