The Astro web framework speeds up websites by sending zero JavaScript to the browser by default.

Most modern websites are slow because they force your phone to download massive files of code just to load a simple page. A new tool called Astro solves this. It uses something called islands architecture. This means it strips away all the heavy code before it reaches your screen. It only loads the interactive parts—like a shopping cart or a search bar—when you actually need them. Your pages load instantly, saving your battery and mobile data.
