What is Astro?
Astro is a content-first web framework that ships zero JavaScript by default. It supports Vue, React, Svelte, and other frameworks via islands architecture, hydrating only interactive components.
What is Nuxt?
Nuxt is a full-stack Vue framework powered by the Nitro server engine. It provides SSR, SSG, ISR, auto-imports, and 200+ modules for common functionality.
Key Differences
JavaScript Output
Astro ships zero JavaScript by default, adding it only for interactive islands. Nuxt ships ~50KB baseline for Vue hydration. For content sites, Astro is dramatically lighter.
Application Architecture
Nuxt is a full-stack app framework with client-side navigation, state management, and Nitro server routes. Astro is content-first with opt-in interactivity via islands.
Framework Flexibility
Astro supports Vue, React, Svelte, and Solid in the same project. Nuxt is Vue-only. If you want to use Vue components without full-framework overhead, Astro is the way.
Content Tooling
Astro has built-in content collections with type-safe Markdown and MDX support. Nuxt uses the Nuxt Content module, which is powerful but an add-on.
Module Ecosystem
Nuxt has 200+ official and community modules for common needs (SEO, auth, analytics). Astro has a growing integration ecosystem but is smaller.
