Next.js vs Astro: which is better for a fast website in 2026?
Choose Astro for content-heavy sites like blogs, marketing pages, and portfolios where you want minimal JavaScript and the fastest load. Choose Next.js for apps or sites with heavy interactivity, dynamic data, or a need for one framework across marketing and product. Both are fast and SEO-friendly; the right pick depends on how much of your site is content versus application.

Frequently asked questions
Is Astro faster than Next.js?
For content-heavy sites, usually yes, because Astro ships zero JavaScript by default. For interactive apps, the comparison is closer, and a well-built Next.js app performs excellently.
Is Astro or Next.js better for SEO?
Both are strong. Astro's light, static-first HTML is excellent for content SEO; Next.js offers SSR and a native Metadata API. The better choice depends on whether your site is content-first or app-first.
Can I use React with Astro?
Yes. Astro is framework-agnostic — you can add React (or Vue, Svelte) components as interactive islands while keeping the rest of the page static and light.
Which should I use for a portfolio?
Either works. Choose Astro if your portfolio is pure content, or Next.js if you already know React or want it to grow into a more interactive site.
