Astro vs Gatsby
Side-by-side comparison of features, pricing, ratings, and alternatives.
Astro is a lightweight web framework that lets developers create fast, content‑rich sites using their favorite UI components. It focuses on delivering minimal JavaScript to the browser while supporting modern development workflows. With built‑in support for static site generation, server‑side rendering, and seamless integration with React, Vue, Svelte, and TypeScript, Astro empowers designers and developers to build highly performant sites without sacrificing flexibility.
Gatsby is an open‑source framework that lets developers build blazing‑fast websites and apps using React, GraphQL, and modern web technologies. It compiles source files into static assets that can be deployed to any web host, delivering optimal performance and SEO out of the box. With a rich plugin ecosystem and seamless integration with headless CMSs and CI/CD platforms, Gatsby empowers agencies and developers to create scalable, secure, and highly maintainable web experiences while keeping the development workflow familiar and efficient.
