Astro
The content-focused framework that ships zero JavaScript by default. Perfect Core Web Vitals
Scorecard
overall 8.8/10The good
- 01Ships zero JavaScript by default: pages are static HTML unless you explicitly add interactivity
- 02Islands architecture lets you use React, Vue, Svelte, or Preact components in the same project
- 03Content Collections provide a type-safe way to manage Markdown, MDX, and structured content
- 04Core Web Vitals scores are effectively perfect on content-heavy sites
- 05Excellent for SEO: static HTML with proper metadata is exactly what search engines want
The not-so-good
- 01Not designed for highly interactive applications (SPAs, dashboards, real-time UIs)
- 02The islands model adds complexity when components need to share state across islands
- 03Smaller ecosystem than Next.js: fewer ready-made integrations and templates
- 04Server-side rendering is capable, but Astro is still less natural for app-heavy workflows than Next.js or Nuxt
- →Content-heavy websites (blogs, documentation, marketing sites, portfolios)
- →SEO-critical projects where page speed directly impacts rankings
- →Teams that want to use components from multiple frameworks without committing to one
- →Projects where most pages are static with only occasional interactive elements
- →Highly interactive applications (dashboards, real-time apps, complex SPAs)
- →Projects that need extensive client-side state management
- →Teams that want a single framework for both content sites and web applications
Our take
Astro answered a question that the frontend community was slow to ask: does every page on your website actually need a JavaScript framework? For content-heavy sites (blogs, documentation, marketing pages, portfolios) the answer is almost always no. Astro ships static HTML by default and only hydrates the specific components that need interactivity. The result is blazing page loads and perfect Core Web Vitals scores without any optimization effort.
The multi-framework support is a practical feature, not a gimmick. You can use React components for your interactive widgets, a Svelte component for a form, and vanilla HTML for everything else, all in the same project. Each island hydrates independently. This matters for teams migrating from another framework or teams where different developers have different preferences.
Content Collections solve the "structured Markdown" problem cleanly. Define a schema for your frontmatter, and Astro validates it at build time with full TypeScript support. If you're building a site with hundreds of content pages (documentation, a blog, a comparison site), this feature alone justifies evaluating Astro.
The limitation is clear: Astro is not built for highly interactive applications. If you're building a dashboard, a real-time collaboration tool, or anything with extensive client-side state, Next.js or SvelteKit are better fits. Astro knows what it's for, executes that vision exceptionally well, and doesn't pretend to be a general-purpose application framework.
