Introduction

Having spent considerable time building real projects with both Astro and Next.js, I often get asked: “Which framework should I choose for my project?”

The short answer? It depends on what you’re building. But let me share my hands-on experience to help you make an informed decision.

I’ve built The World Explorer using Next.js and my personal portfolio at prakashraj.info using Astro. This real-world experience has given me insights into when each framework truly shines.

What is Astro?

Astro is what I like to call the “performance-first” framework. It’s designed with a simple philosophy: send as little JavaScript to the browser as possible.

The Astro Philosophy

When I first started working on my portfolio with Astro, what struck me most was its “Zero JavaScript by default” approach. Unlike traditional frameworks that hydrate everything, Astro only adds JavaScript where you explicitly need it.

This is achieved through Astro’s Component Islands Architecture - imagine your page as an ocean with small islands of interactivity. Most of your content remains static HTML, while only specific components become interactive.

My Experience Building with Astro

Building prakashraj.info with Astro was refreshingly straightforward:

What I Loved:

  • Blazing Fast Performance: My portfolio consistently scores 100/100 on PageSpeed Insights
  • Framework Flexibility: I could use React components for complex interactions while keeping most content static
  • Markdown Integration: Writing blog posts in MDX felt natural and productive
  • Simple Mental Model: No complex state management or hydration concerns

Perfect for:

  • Personal portfolios
  • Blogs and content sites
  • Marketing websites
  • Documentation sites
  • Landing pages

What is Next.js?

Next.js is React’s full-stack framework - it’s like having a Swiss Army knife for web development. Backed by Vercel, it’s designed to handle everything from simple static sites to complex enterprise applications.

The Next.js Approach

When building The World Explorer, I needed dynamic features like real-time data fetching, complex user interactions, and server-side rendering. Next.js excelled in all these areas.

My Experience Building with Next.js

Creating The World Explorer taught me why Next.js is so popular in the enterprise world:

What I Loved:

  • Full-Stack Capabilities: API routes, middleware, and server components in one framework
  • Dynamic Rendering: ISR (Incremental Static Regeneration) for the perfect balance of performance and freshness
  • Rich Ecosystem: Extensive libraries, UI components, and third-party integrations
  • Developer Experience: Hot reloading, TypeScript support, and excellent debugging tools

Perfect for:

  • E-commerce platforms
  • SaaS applications
  • Dashboards and admin panels
  • Social media platforms
  • Complex interactive websites

Performance: The Numbers Don’t Lie

After building both projects, here’s what I observed:

Astro Performance (prakashraj.info)

  • Bundle Size: ~25 kB JavaScript
  • Largest Contentful Paint: 0.7 seconds
  • PageSpeed Score: 100/100 consistently
  • First Load: Lightning fast due to minimal JavaScript

Next.js Performance (theworldexplorer.vercel.app)

  • Bundle Size: ~180 kB JavaScript (with all features)
  • Largest Contentful Paint: 1.2 seconds
  • PageSpeed Score: 85-95/100
  • First Load: Slightly slower but offers rich interactivity

The Verdict: Astro wins on pure performance, but Next.js offers more functionality for the extra weight.

Developer Experience: A Tale of Two Approaches

Astro Developer Experience

Working with Astro felt like a breath of fresh air:

---
// Component script (runs at build time)
const posts = await fetchBlogPosts();
---

<html>
  <head>
    <title>My Blog</title>
  </head>
  <body>
    <main>
      {
        posts.map((post) => (
          <article>
            <h2>{post.title}</h2>
            <p>{post.excerpt}</p>
          </article>
        ))
      }
    </main>
  </body>
</html>

Pros:

  • Clean, intuitive syntax
  • Less boilerplate code
  • Excellent Markdown/MDX support
  • Simple project structure

Cons:

  • Limited dynamic capabilities
  • Smaller community (though growing rapidly)
  • Fewer third-party integrations

Next.js Developer Experience

Next.js provided enterprise-grade tooling:

// Server Component
async function BlogList() {
  const posts = await fetch('/api/posts').then((res) => res.json());

  return (
    <div>
      {posts.map((post) => (
        <BlogPost key={post.id} post={post} />
      ))}
    </div>
  );
}

// API Route
export async function GET() {
  const posts = await db.posts.findMany();
  return Response.json(posts);
}

Pros:

  • Comprehensive feature set
  • Excellent TypeScript support
  • Rich debugging and development tools
  • Massive ecosystem and community

Cons:

  • Steeper learning curve
  • More complex project structure
  • Heavier initial setup

SEO: Both Excel, Different Approaches

Astro SEO

My portfolio naturally ranks well because:

  • Static HTML by default
  • No hydration delays
  • Excellent Core Web Vitals
  • Clean, semantic markup

Next.js SEO

The World Explorer required more setup but achieved:

  • Server-side rendering for dynamic content
  • Proper meta tag management
  • Structured data support
  • Good performance with optimization

Ecosystem and Community

Astro Ecosystem

  • Integrations: 100+ official integrations
  • Community: Smaller but passionate and helpful
  • Learning Resources: Excellent documentation, growing tutorial base
