Both Astro and Next.js can serve as frontends for headless WordPress, but they take very different approaches.

Astro: Content First

Astro ships zero JavaScript by default. It is designed for content-heavy sites where interactivity is minimal. Perfect for blogs, marketing sites, and documentation.

Next.js: App First

Next.js is a full React framework. It excels when you need complex interactivity, user authentication, or real-time features.

The Verdict

For a WordPress blog or content site, Astro is the better fit. It is simpler, faster, and ships less code to the browser. For web applications that happen to use WordPress content, Next.js may be more appropriate.
