What is Static Site?

A static site is a website composed of pre-rendered HTML, CSS, and JavaScript files that are served directly to visitors without any server-side processing. Unlike dynamic sites that generate pages on each request using databases and server logic, static sites are built once at deploy time and served as-is from a CDN.

Static sites consistently achieve Lighthouse scores of 95-100, with Time to First Byte under 50ms from edge locations worldwide. They have zero server-side attack surface — no database to inject, no PHP to exploit, no admin panel to brute-force.

Modern static site generators like Astro, Next.js, and Hugo combine the performance benefits of static output with developer-friendly authoring experiences including component-based architecture, markdown content, and build-time data fetching.
