Next.js and React development for fast, SEO-friendly sites and apps
CodersDuniya builds websites and web applications with Next.js and React, including migrations from WordPress or older React apps. Next.js renders pages on the server, which makes them fast and easy for Google and AI search engines to read. Marketing sites start around ₹40,000; full applications cost ₹1.5–5 lakh (plus GST).

Who this is for
- Businesses that need top Core Web Vitals and SEO
- Startups building a SaaS product with a marketing site
- Teams with a slow React single-page app that Google struggles to index
- Companies moving off a heavy WordPress theme
Problems this solves
A React app that Google can't read well
Client-only rendering hides content from crawlers. Next.js renders it on the server.
WordPress is slow and keeps breaking
Too many plugins and updates. A Next.js site with a simple CMS is faster and more secure.
Poor Core Web Vitals
We fix LCP, INP and CLS with server rendering, image optimisation and less JavaScript.
Separate teams for site and app
One Next.js codebase can serve the marketing site and the logged-in app.
What we build and do
Server-rendered pages
Static and server rendering so content is in the HTML from the first byte.
Headless CMS
Edit content in Sanity, Strapi or Supabase without touching code.
Full-stack features
Auth, payments, database and APIs with Next.js and Node.js.
SEO architecture
Metadata, sitemaps, structured data and internal linking built in.
Migration without ranking loss
URL mapping and 301 redirects so existing rankings carry over.
Deployment
Vercel, Netlify or your own server, with preview links for every change.
Why CodersDuniya
Performance is the default
We measure Core Web Vitals before and after, and share the numbers.
Typed, tested code
TypeScript throughout, so future changes are safer.

Common questions
Is Next.js better than WordPress for SEO?
Both can rank well. Next.js makes it easier to get excellent speed and clean HTML, which helps. WordPress is easier for non-technical teams to edit. The content and links you build matter more than the platform.
Will migrating to Next.js hurt my rankings?
Not if it's done properly. We keep URLs where possible, redirect the rest with 301s, and carry over titles, descriptions and structured data. Short fluctuations can happen; long-term speed usually helps.
How much does a Next.js website cost?
A Next.js marketing website with CodersDuniya starts around ₹40,000 plus GST. Full web applications usually cost ₹1.5–5 lakh.
