Most websites send your visitors far more JavaScript than the page actually needs, and every unnecessary kilobyte costs speed, battery and carbon. Astro is the framework built on the opposite instinct: ship zero JavaScript by default, and add interactivity only where a component truly needs it.
At Lemon Hive we use Astro for content-first builds: marketing sites, publications, brand sites and storefronts where the experience is rich but the interactivity is selective. It is the leanest thing we build, and for the right project, the fastest.
