Next.js App Router vs Pages Router: Which Should You Use in 2026?

If you're starting a new Next.js project, the most important routing decision is usually straightforward: the App Router should be your default choice for a new application.

But that does not mean the Pages Router is obsolete.

Next.js officially supports both routers. The App Router is the newer architecture and is designed around newer React capabilities, including Server Components. The Pages Router remains supported and continues to be maintained. :contentReference[oaicite:1]

The real question is therefore not:

"Which router is better?"

It is:

"Which router makes sense for my project?"

This guide compares both approaches and explains when you should use the App Router, when keeping the Pages Router is reasonable, and how to approach a migration without creating unnecessary risk.

Quick Answer

For most new Next.js applications in 2026, I recommend the App Router.

Choose the App Router if you:

• Are starting a new project
• Want to use Server Components
• Want the current Next.js architecture
• Are building a SaaS application
• Need modern routing and layouts
• Want to follow current Next.js learning resources
• Expect the application to evolve over time

Keep the Pages Router when:

• You already have a stable production application
• Migration provides little business value
• Your existing architecture works well
• The migration would introduce unnecessary risk
• Your team has strong expertise in the existing codebase

The key principle is simple:

Don't migrate because a newer architecture exists. Migrate when the new architecture solves a real problem.

App Router vs Pages Router at a Glance

| Area | App Router | Pages Router | |---|---|---| | Architecture | Modern Next.js architecture | Original Next.js router | | Server Components | Supported | Not the App Router model | | Routing | File-system based | File-system based | | Layouts | Built into routing architecture | Usually implemented differently | | Data fetching | Modern Server Component patterns | Traditional Next.js data fetching | | API routes | Route Handlers | API Routes | | New projects | Recommended starting point | Usually not first choice | | Existing projects | Excellent target for gradual adoption | Often best to keep if stable | | Migration complexity | Can require architectural changes | No migration required | | Current Next.js direction | Primary modern architecture | Still supported |

Next.js describes the App Router as the newer router supporting new React features, while the Pages Router is the original router and remains supported. :contentReference[oaicite:2]

What Is the Next.js App Router?

The App Router uses the app directory to organize routes and application structure.

A simple project might look like:

app/
├── layout.tsx
├── page.tsx
├── dashboard/
│   ├── page.tsx
│   └── settings/
│       └── page.tsx
└── blog/
    └── page.tsx
