Building Scalable SaaS Applications with Next.js 15 and Django

Why Next.js + Django?

The combination of Next.js and Django gives you the best of both worlds: React's powerful UI capabilities with Django's robust backend framework. Next.js 15's App Router provides server components, streaming, and excellent SEO, while Django offers a battle-tested ORM, admin interface, and extensive ecosystem.

Architecture Overview

Our recommended architecture uses Django REST Framework for API endpoints, PostgreSQL for data storage, Redis for caching and real-time features, and Next.js for server-side rendering with client-side interactivity where needed.

// Example: Fetching data with Next.js Server Components
async function DashboardPage() {
  const data = await fetch('https://api.example.com/dashboard', {
    next: { revalidate: 60 }
  });
  const stats = await data.json();
  return <Dashboard stats={stats} />;
}

Key Takeaways

When building SaaS applications, focus on: clean API design, proper authentication (JWT + refresh tokens), database optimization with proper indexing, and a robust CI/CD pipeline for continuous deployment.
