Choosing the right framework for your web project can make the difference between a fast, well-ranked site on Google, or a slow and expensive one to maintain. We compare React and Astro from what matters to a business: performance, SEO, and maintenance cost.
Astro: native speed and first-class SEO
Astro is a framework designed for content sites: portfolios, blogs, corporate sites, landing pages. Its main advantage is that it generates static HTML by default, without unnecessary client-side JavaScript.
- Perfect Core Web Vitals: No render-blocking JavaScript
- Exceptional SEO: Pure HTML that Google indexes optimally
- Framework-agnostic: Can use React, Vue, or Svelte components inside Astro
- Ideal for: Corporate sites, blogs, portfolios, landing pages
React: the standard for complex applications
React shines when you need highly interactive interfaces: dashboards, SaaS apps, platforms with complex state and frontend business logic.
- Complex state: Redux, Zustand, Context for real-time dynamic data
- Huge ecosystem: The largest component library on the market
- Ideal for: SaaS, internal platforms, apps with frequent interactions
The concrete answer
Need a website for your company or a landing page? Astro. Faster loads, better SEO, lower maintenance cost.
Need a custom web platform to digitize a business process? React — or a combination: Astro for the public site and React for the internal app.
