Description #
Astro is a modern frontend framework focused on delivering ultra-fast websites by shipping less JavaScript. It allows developers to use multiple UI frameworks (React, Vue, Svelte, etc.) in one project and renders pages as static HTML by default, enhancing performance and SEO.
History #
Astro was launched in 2021 by Fred K. Schott and the team at The Astro Technology Company. It quickly gained popularity for its innovative “Islands Architecture” and zero-JS-by-default approach. Astro is now widely adopted for static sites, blogs, documentation, and modern web apps.
