Jon Doe • 2 min •

Astro is a modern front-end framework that provides developers with a faster way to build websites. It brings about an interesting paradigm shift in how we think about building modern web applications.

What is Astro?

What is Astro?

Astro is a new type of JavaScript-based static site generator. Unlike other popular frameworks like React, Vue, and Angular, Astro does not send any JavaScript by default. Instead, Astro only sends HTML, CSS, and as little JavaScript as you need. This results in faster load times and better performance for your web apps.

Astro is built to take advantage of modern browser features, like HTTP/2 and server components. This allows you to build highly interactive sites, without the typical cost associated with sending large JavaScript bundles to the client.
