In short

Next.js development services cover architecture, design, build and deployment of Next.js 15 applications — marketing sites, SaaS apps, ecommerce storefronts and headless CMS frontends — engineered for Core Web Vitals, SEO and conversion.

  • Sub-2s LCP with App Router + RSC + image optimization
  • Built-in SEO: metadata, sitemaps, schema, OG, canonical
  • Headless commerce + headless CMS on Vercel or Cloudflare

The problem

Why this matters now

Most Next.js builds ship with the wrong rendering strategy — everything is a client component, SSR is misused, images aren't optimized, and the App Router is fought instead of leveraged. The result is a 'modern' site that's slower than the WordPress it replaced.

Our approach

How Marketer Zilla delivers

We start with a rendering plan per route — static, ISR, RSC streaming, dynamic, or edge — based on the page's job. The result is a Next.js app that gets the speed, SEO and DX benefits of the framework without the common production pitfalls.

Why Marketer Zilla

A senior team built to win modern search and modern paid.

App Router done right

Server-first by default, client components only where interactivity demands it. Smaller bundles, faster pages, better SEO.

SEO is non-negotiable

Metadata API, dynamic sitemaps, OG images, canonical and schema on every route — not bolted on later.

Speed budgets, not aspirations

We set LCP, INP and CLS budgets in week one and ship dashboards that flag regressions before they ship.

Headless when it helps

Sanity, Contentful, Payload or WordPress as the content layer — picked for your team, not our preference.

Edge-ready

Middleware, rewrites, A/B tests, geo and personalization at the edge — no origin round-trips.

Senior engineers only

Every Next.js project is led by an engineer with 5+ years of React and production Next.js shipping experience.

Next.js is the right call when SEO, server-side rendering, image optimization, edge routing or hybrid static/dynamic rendering matter. For pure SPAs with no SEO needs, Vite + React or TanStack Start may be lighter — we'll recommend honestly based on your goals.
App Router on every new build. It's the supported direction, gives us React Server Components, streaming, partial pre-rendering and a much better caching model. We migrate Pages Router apps to App Router as part of refactor engagements.
Next.js 15 + React 19 as the default. We stay on 14 only when a critical dependency hasn't shipped 15 support yet.
Sanity and Payload are our defaults for marketers. Contentful for enterprise content ops. Headless WordPress when an existing WP editorial team must stay. We choose based on your team, not our preference.
Yes. Next.js + Shopify Storefront API, Medusa, Saleor or BigCommerce headless. Best for brands needing speed, custom UX or content-led commerce beyond what Shopify themes allow.
Yes — that's a non-negotiable. We pair Next.js with a headless CMS so marketers can ship pages, blog posts and landing pages without involving engineering.
Marketing sites: 6–10 weeks. SaaS apps and headless commerce: 10–20 weeks. Discovery happens first and the timeline is fixed at the end of it, not estimated upfront.
Yes — from WordPress, Webflow, Gatsby, CRA, Vite and legacy Next.js. We run an SEO migration plan (redirects, schema, content audit) so rankings stay intact.
