Overview
Astro is a web framework for content-driven websites with island architecture and zero JS by default. It handles island architecture, zero js, ssg/ssr, and content collections, and it's best suited for developers wanting content-focused static sites. It has been around since 2021, giving it a 5-year head start in building out integrations and refining the product.
