Next.js
Our default framework for anything public-facing that must be fast and findable.
Next.js is the framework we reach for when a product has a public surface that has to be fast, indexable and maintainable by a team rather than an individual. We have been shipping it since the Pages Router era, migrated production estates to the App Router when it stabilised, and now run a set of internal conventions that keep new projects out of the traps that catch most teams.
What makes it the right default is not any single feature but the combination: server-rendered HTML that search engines and AI crawlers read completely, per-route control over how each page is produced, a component model that scales across a team, and image, font and script handling that would otherwise be assembled by hand on every project.
What makes it dangerous is that it is fast by default and slow by accident. A single client boundary drawn too high in the tree pulls hundreds of kilobytes into the browser for a page that is mostly text. That is why our engagements start with a rendering strategy per route rather than with a component library.
Where it fits
What Next.js genuinely gives us
Complete HTML on first response
Content is present before JavaScript executes, which is what makes a page reliably indexable and citable by AI answer engines.
Rendering choice per route
Static for marketing, ISR for catalogues, dynamic for search, per-user for dashboards — decided route by route rather than project-wide.
Streaming with Suspense
Expensive sections load without blocking the rest of the page, which improves perceived speed far more than raw optimisation.
Built-in asset discipline
Image optimisation, font subsetting and script strategy come with the framework instead of being reinvented each project.
How we decide the rendering strategy
The single largest lever on both performance and hosting cost is deciding how each route is produced. Our default is aggressive: statically generate everything that can be static, revalidate on demand when the underlying content changes, stream anything expensive, and render dynamically only when the response genuinely depends on the request.
A services page has no reason to be computed per visit. A stock-availability widget does. Separating them at the component level rather than the page level is precisely what React Server Components make possible, and it is where most of the win lives.
Keeping the client bundle honest
We enforce a simple discipline: server by default, client only at the leaf, and every client component justified in code review. Interactive islands — a calculator, an accordion, a filter panel — are isolated and lazy-loaded. Heavy dependencies are dynamically imported behind an interaction or a viewport trigger.
Per-route JavaScript budgets are enforced in continuous integration and the build fails when a route exceeds its budget, so regressions are caught by the machine rather than by a customer complaint six weeks later.
Metadata and structured data generated, never hand-written
Metadata for each route is generated from the same content source that renders the page, so a title can never drift from its heading. Structured data is emitted as JSON-LD from typed objects rather than hand-assembled strings, which is why our schema actually validates. Sitemaps and feeds are produced from the same registry that builds the routes, so a new page cannot be published and forgotten.
How Next.js projects usually go wrong
These are the failure modes we look for first when we are called in to rescue somebody else's implementation.
Next.js questions we get asked
Including where we would recommend something other than Next.js. Call +91 70033 91355 and you will get the same answer from an engineer.
No. Vercel is the smoothest path and we use it often, but we also deploy Next.js on AWS with ECS or Amplify, on Google Cloud Run, on Azure Container Apps and on plain Docker in a private data centre. Self-hosting is viable and sometimes materially cheaper at scale, but you take on cache and image-optimisation responsibilities that Vercel handles for you — we will price both honestly.
Not in our experience. A five-page site built on Next.js and statically generated costs essentially nothing to host, loads in under a second and needs no maintenance beyond dependency updates. The complexity people fear is in the application features, which a small site simply does not use.
The current stable release, kept one minor version behind the bleeding edge as a deliberate risk stance. Upgrades are part of maintenance plans and tested on a preview environment first. We do not use experimental flags in production work without a specific agreed reason and a rollback path.
