Astro and Next.js overlap on SEO-friendly websites, but their center of gravity is different. Astro is content-first: static output, islands of interactivity, framework flexibility, and minimal JavaScript by default. Next.js is application-first: React Server Components, flexible rendering modes, API routes, middleware, and a large full-stack deployment ecosystem.
For documentation, marketing sites, guides, and mostly-static content hubs, Astro's default performance model is hard to beat because interactive components are opt-in. For SaaS dashboards, authenticated apps, product surfaces, and teams standardizing on React, Next.js gives you more integrated primitives and a deeper production ecosystem.
The deciding question is not "which has better SEO?" Both can produce crawlable, fast pages. The deciding question is whether the project is primarily a content site with a few interactive islands or a full-stack React application with content pages attached.
