Why We Choose Next.js App Router for Every Project

After shipping 12+ production products — from vehicle marketplaces to OTT platforms to affiliate engines — we've settled on Next.js App Router as our default web stack. Here's why.
Server Components by default
With the App Router, every component is a Server Component unless you opt into 'use client'. This means your data-fetching logic runs on the server, giving you zero loading spinners for initial data, smaller JS bundles, and better SEO out of the box.
Nested layouts without re-renders
The layout system in App Router lets you share UI between routes without re-mounting it. A sidebar, admin shell, or page header stays mounted as you navigate — no flicker, no wasted renders.
SEO built in
The Metadata API (generateMetadata) gives you dynamic, per-page title tags, OG images, canonical URLs, and JSON-LD schema with TypeScript safety. Pages Router required a lot of <Head> boilerplate and was easy to get wrong.
Streaming & Suspense
Slow API? Wrap it in <Suspense> and stream the response progressively. The shell HTML reaches the browser instantly, improving Time to First Byte and Largest Contentful Paint.
When we'd still use Pages Router
Legacy projects, or if the team has deep Pages Router expertise and the migration cost outweighs the benefits. For new projects starting in 2024+, App Router is the clear choice.
Our default stack
- Next.js 15+ App Router
- TypeScript
- Tailwind CSS
- Node.js + Express backend
- PostgreSQL
- Deployed on Vercel + Render
Every project we ship at CodeTagz uses this stack unless there's a specific reason not to. It's battle-tested, fast, and keeps both developers and clients happy.
