Short answer

Next.js is the React framework we use for most new web products because it renders pages on the server, ships less JavaScript and gives search engines complete HTML. A Next.js development engagement with Innovation Insight runs from $15k for a content site or MVP to $100k or more for a multi-role SaaS, with TypeScript, Tailwind and deployment on Vercel or AWS, delivered by engineers who have shipped on the App Router since it launched.

Why teams choose Next.js

Next.js takes React, the library most front-end engineers already know, and adds the things a product needs to be fast and findable: server rendering, static generation, file-based routing, image and font optimisation, and an API layer in the same codebase. The result is a site that loads quickly on a phone, gives Google and AI crawlers complete HTML, and lets one team ship front end and back end together. It is the framework behind this site, which is why every page here renders in under a second on desktop and passes Core Web Vitals.

App Router and server components, in plain terms

The App Router is the current way to build Next.js applications. Pages are made of server components by default, which run on the server and send finished HTML, and client components only where the user interacts, such as a form or a menu. For a buyer this means two things: pages are lighter and faster because less code reaches the browser, and features like metadata, sitemaps and structured data are generated by the same code that renders the page, so SEO stops being an afterthought. Our engineers have worked in the App Router since Next.js 13 and follow the patterns the framework team recommends, so the code we hand over is the code a Next.js specialist would expect to find.

What we build with Next.js

  • Marketing and content sites with a headless CMS (Sanity, Contentful, Strapi) and editorial workflows.
  • SaaS front ends and dashboards with authentication, billing and role-based access.
  • E-commerce storefronts on Shopify Hydrogen alternatives, headless Shopify or custom catalogues.
  • Full-stack applications where API routes and server actions replace a separate backend for small to medium products.
  • Design systems in Tailwind and shadcn/ui shared across several products.
  • Migrations from WordPress, Create React App, Gatsby, Angular and .NET MVC front ends.

When Next.js fits, and when it does not

Next.js is the right default for anything public-facing where performance and search matter, and for product front ends that need server-side data access. It is a poor fit for heavy real-time canvases such as design tools, where a plain client app is simpler; for teams whose backend is a large existing API in another language and who only need a thin static front end; and for organisations that have no Node.js operations experience and no wish to acquire it, in which case we will say so and propose something they can run.

Migrating to Next.js without losing traffic

Most of our Next.js work starts as a migration. The risk is not the code, it is the search traffic and the links the old site has earned. We start with a crawl of the existing site, a URL-by-URL redirect map, and a metadata inventory. The new site is built to parity first, checked page by page against the old one, then launched behind 301 redirects with Search Console monitoring for the following month. Our own site was migrated this way in one release and every retired URL still resolves.

  1. Audit: crawl, analytics review, list of pages that earn traffic and links.
  2. Information architecture: what stays, what merges, what is retired, with a redirect for every old URL.
  3. Build: design system, templates, CMS integration, content migration scripts.
  4. Parity and performance: side-by-side checks, Lighthouse and Core Web Vitals on every template.
  5. Launch: DNS switch, redirects live, sitemap resubmitted, monitoring for 30 days.
A migration is also the cheapest moment to fix years of accumulated SEO debt: duplicate titles, missing structured data, slow images. We fold that into the parity checklist rather than charging for it separately.

Innovation Insight is a custom software development company with 50 or more engineers, designers and project managers in Lahore and Sialkot, Pakistan. Next.js is our default for web work, and our case studies show the stack behind each product.

Performance we hold ourselves to

Every Next.js site we ship is measured against Core Web Vitals before launch: Largest Contentful Paint under 2.5 seconds on a throttled mobile connection, Interaction to Next Paint under 200 milliseconds, and no layout shift. We reach those numbers with server components for content, client components only where there is interaction, next/image for every photo, fonts loaded through next/font, and a hard limit on third-party scripts. The budgets are written into the definition of done so a heavy dependency cannot creep in during a later sprint.

MetricTarget at launchHow we get there
Largest Contentful PaintUnder 2.5 s mobileServer rendering, image sizing, preloaded fonts
Interaction to Next PaintUnder 200 msMinimal client JavaScript, no blocking work on input
Cumulative Layout ShiftUnder 0.1Explicit image dimensions, reserved space for dynamic content
JavaScript per pageUnder 250 KB gzippedDynamic imports, no analytics until consent, tree-shaken libraries

What we hand over

  • A TypeScript codebase with a documented folder structure, linting and formatting configured.
  • A design system with tokens and components that your team can extend.
  • Automated tests in CI and a preview deployment for every pull request.
  • SEO foundations: metadata per route, canonical URLs, sitemap, robots, structured data and share images.
  • A runbook covering deployment, environment variables, CMS workflows and incident contacts.

What to bring to the first call

Bring your current site or product URL, analytics access if you have it, and a list of what frustrates you today, whether that is speed, editing content, search rankings or the cost of changes. For a migration we also ask for the CMS export and the list of integrations, so the redirect map and the content scripts can be scoped accurately. Within a week you get a written plan with the architecture, the timeline and a fixed estimate, and you decide whether to continue.

FAQ

Questions we get asked a lot.

Do you use the App Router or the Pages Router?

The App Router for all new work, because it is where the framework's investment is going and it produces lighter pages. We maintain Pages Router applications and migrate them when a client is ready.

Can you host on our own AWS instead of Vercel?

Yes. We deploy Next.js on AWS with OpenNext or containers when you need your own cloud for compliance or cost reasons. Vercel is faster to set up and is what we recommend for most teams.

Will our WordPress content editors cope with a headless CMS?

Yes, with a short walkthrough. We choose a CMS with an editing experience close to what they know and migrate content with scripts so nothing is retyped.

How do you protect SEO during a migration?

A redirect map for every old URL, metadata parity checks, structured data on the new templates, and Search Console monitoring for a month after launch.

Can you take over an existing Next.js codebase?

Yes. We start with a code and performance audit, fix the highest-risk items, and then continue feature work in your repository.

What does a Next.js developer cost on a monthly basis?

Our React and Next.js developers are $3,000 to $7,200 a month depending on seniority, full-time and all-inclusive. See the hire React developers page for the full table.
