Next.js Development Company in India

Description

Service Next.js development

WavX builds websites and web applications in Next.js, the React framework for full-stack web applications. As of October 2026 the supported line is Next.js 16, with 16.3 the latest release. New builds use the App Router and Server Components, run on infrastructure the client owns, and are priced as planning ranges from the software cost estimator before a scoped quote.

Next.js as of October 2026

The Next.js documentation describes it as "a React framework for building full-stack web applications". It is open source under the MIT licence, so there is no licence fee. The facts that matter to a buyer today:

Fact

Status on 2 October 2026

Supported major versions

16.x is Active LTS (released 21 October 2025). 15.x is Maintenance LTS. 14.x and earlier are unsupported

Latest release

Next.js 16.3, published 3 August 2026. The documentation is at 16.3.8

Security patches

The September 2026 security release, published 30 September, shipped its fixes in 16.3.8 and 15.5.27

Routers

App Router (the newer router, built on React Server Components) and Pages Router (the original, still supported)

Bundler

Turbopack is the default; Webpack remains available behind a flag

Minimum Node.js

20.9. Node.js 20 is itself listed as end-of-life on nodejs.org, so production should run Node.js 22 or 24, the two LTS lines

Under the support policy, a major version stays in Active LTS until the next major is released, and remains in Maintenance LTS for two years following its initial release. Next.js 15 was released on 21 October 2024, so a project on 15 should plan its move to 16 now. A site on version 13 or 14 is already outside the policy, which is the usual reason an upgrade project starts.

How Next.js renders a page

These are the terms a proposal will use. The definitions follow the Next.js glossary and documentation.

Term

What it means

Typical use

Server Component

The default component type in the App Router. Renders on the server, can fetch data directly, and adds nothing to the JavaScript sent to the browser. Cannot use state or browser APIs

Content, product data, anything read from a database

Client Component

Marked with the "use client" directive. Can use state, event handlers and browser APIs

Forms, filters, carts, anything interactive

Prerendering

A component is rendered at build time or in the background during revalidation. The HTML can be cached and served from a CDN

Marketing pages, articles, catalogues

Dynamic rendering

A component is rendered at request time, because it reads cookies, headers or URL query parameters

Account pages, personalised content

Streaming

The server sends parts of the page as they become ready, using <Suspense> boundaries or a loading.js file

Slow data that should not hold up the rest of the page

Partial Prerendering

A static shell is served immediately while dynamic content streams in

A product page with a static description and a live stock count

Cache Components

Opt-in with cacheComponents: true . The "use cache" directive caches a function or component, and Partial Prerendering becomes the default behaviour

New builds that mix static and personalised content

Incremental Static Regeneration

Static content is updated without rebuilding the whole site

Large catalogues and blogs

Server Function

An asynchronous function that runs on the server, marked "use server" . Called a Server Action when bound to a form

Form submissions and data changes

Route Handler

A function in a route.js file that handles HTTP requests

API endpoints, webhooks

Proxy

A proxy.js file that runs before a request completes. Formerly called Middleware

Redirects, rewrites, access checks

Two points from the 16.3 release affect how a new project should be set up. First, Cache Components shipped in 16.0 and are still opt-in. Second, 16.3 added Instant Navigations, an opt-in set of tools that prefetch a loading shell so navigation feels immediate, and the release post states that these behaviours will become the default in a future major version. A project started now should decide whether to adopt that model from the first commit, because retrofitting a caching model is more work than starting with it.

One detail matters for search and AI crawlers. With Cache Components, the documentation states that bots are detected by user agent and receive a fully rendered page at request time instead of the static shell. Data that the shell needs must therefore also be available at request time, or a page that loads for a person can fail for a crawler. WavX tests the crawler path as well as the browser path.

What WavX builds with it

WavX's web stack is React, Next.js, Node.js, Python, TypeScript, PostgreSQL, MongoDB and Tailwind CSS, deployed on AWS, Google Cloud or Azure.

Work

What it covers

New website

Corporate and business sites and landing pages, prerendered, with a CMS where editors need one

New web application

SaaS platforms, dashboards, customer and vendor portals, with authentication, role-based access and payments

Storefront

A custom store front end, or a headless commerce build on an existing commerce back end

Version upgrade

Moving an unsupported version to the current LTS line, including the Middleware to Proxy change and the move to Turbopack

Router migration

Pages Router to App Router, page by page, while the site stays live

Platform migration

WordPress or another CMS to Next.js, handled as a site migration with a URL map and redirects, so search traffic is carried over

Design to code

Building from an approved design. See Figma to production code

Takeover

Continuing a Next.js project another team started, after an audit. See software rescue

You own 100% of the source code and IP that WavX ships. The repository, the hosting account and the domain are set up in your company's name.

Hosting

The documentation lists four deployment options, and the choice changes which features are available.

Option

Feature support, per the docs

Notes

Node.js server

All

Any provider that runs Node.js

Docker container

Any container host, including Kubernetes and cloud container services

Static export

Limited

Plain HTML, CSS and JavaScript on any static host. No cookies, redirects, Proxy, Server Actions, Incremental Static Regeneration or default image optimisation

Adapters

Varies

Vercel and Bun are listed as verified adapters. AWS Amplify, Cloudflare, Netlify, Firebase App Hosting and others offer their own integrations, which the Next.js team does not verify

For a self-hosted application, caching and image optimisation need configuring for the infrastructure. The September 2026 security release included a cache-poisoning fix that applied specifically to self-hosted applications, which is a reminder that self-hosting saves platform fees and adds patching responsibility.

Planning range

Cost follows the size of what is being built. The figures below come from the software cost estimator . They assume small scale (up to about 1,000 users) and standard design, and each range is the subtotal less 15% to plus 25%. They are planning ranges, not quotes.

Build

Subtotal

Internal tool or dashboard, no added features

₹2,00,000

₹1,70,000 to ₹2,50,000

Custom web application with auth and roles, and an admin panel

₹6,00,000

₹5,10,000 to ₹7,50,000

SaaS product with auth and roles, payments, and an admin panel

₹9,40,000

₹7,99,000 to ₹11,75,000

Custom design multiplies the subtotal by 1.25 and growing scale (1,000 to 50,000 users) by 1.3. A marketing website costs less than any of these; the web development guide gives an indicative starting point of ₹50,000. Upgrades, migrations and takeovers are quoted after an audit, because the cost depends on the code that exists.

Engagements are fixed price, time and materials, or a hybrid, quoted after a free consultation. The same applies if you want Next.js developers working alongside your own team.

Timeline

The timelines WavX states are 4 to 6 weeks for a simple website and 3 to 6 months for a complex e-commerce or ERP/CRM platform. The estimator shows a week band for each selection. A build runs in this order:

Scope. Page types, data sources, user roles, integrations, and which pages are static and which are personalised.

Architecture. Router, rendering mode per route, caching model, hosting target.

Design. Screens approved in Figma before they are coded.

Build. Components first, then routes, then integrations.

Checks. Performance against Core Web Vitals, server-rendered HTML for crawlers, access control, error handling.

Launch and handover. Deployment to your account, with written build and deploy instructions.

When Next.js is the wrong choice

A small site that non-technical staff edit daily. WordPress or a hosted site builder will be cheaper to run and easier to hand to a marketing team. The comparison is in Next.js vs WordPress .

A standard Shopify store. A theme is cheaper to build and maintain than a headless front end. Read when headless Shopify is worth it first.

An internal tool with a handful of users. Server rendering and search visibility add nothing behind a login. A plain React application, or an off-the-shelf tool, may do.

A team that works in another framework. If your developers know Vue or Angular, choose what they can maintain.

Nobody will maintain it. Next.js published security releases in both August and September 2026. A site that will never be patched is safer on a hosted platform that patches itself. If you do build, budget for website maintenance .

Frequently asked questions

Which version of Next.js do you build on?

New projects start on the current Active LTS line, which is Next.js 16 as of October 2026. Next.js 15 is in Maintenance LTS and versions 14 and earlier are listed as unsupported, so an older project should plan an upgrade.

App Router or Pages Router?

New builds use the App Router, which supports Server Components. The Next.js documentation describes the Pages Router as still supported and being improved, so an existing Pages Router application does not need an emergency migration. We move it when there is a reason, such as needing streaming or server components.

Do we have to host on Vercel?

No. The Next.js documentation lists four ways to deploy: a Node.js server, a Docker container, a static export, or a platform adapter. Node.js and Docker deployments support every feature. We deploy to an account in your company&#x27;s name, on AWS, Google Cloud, Azure or the platform you already use.

Is Next.js better for SEO?

It renders HTML on the server, so crawlers receive the page content without running JavaScript, and it gives control over metadata and structured data. That removes technical obstacles. It does not produce rankings; those depend on content, links and competition, and we do not promise them.

Can you take over an existing Next.js project?

Yes, after an audit of the code, the version it runs and how it is deployed. The audit tells you whether the code is worth continuing before any repair work is quoted.

How much does a Next.js project cost?

It depends on what is being built, not on the framework. The software cost estimator gives a planning range: for example ₹5,10,000 to ₹7,50,000 for a custom web application with logins, roles and an admin panel at small scale with standard design. A firm quote follows a scoping call.
