What makes it fast
Performance is baked in, not bolted on.
Optimized assets
Fonts are preloaded, CSS is purged and minified, images are processed with Astro's built-in asset pipeline for optimal formats and sizes.
Static-first
Pages are pre-rendered to static HTML at build time, served from CDNs with sub-millisecond TTFB anywhere in the world.
Critical CSS inlined
Above-the-fold styles are inlined directly in the HTML document, eliminating render-blocking requests for first paint.
SEO defaults
Open Graph tags, Twitter cards, canonical URLs, sitemaps, and structured metadata come preconfigured for maximum discoverability.
Accessible by design
Semantic HTML, keyboard navigation, ARIA labels, and color contrast are checked at the component level, not as an afterthought.
