SSG (Static Site Generation)

Quick Definition

SSG pre-renders pages at build time into static HTML files served from a CDN. It's the fastest possible serving method.

In context

Frameworks like Astro, Next.js, Eleventy, and Hugo support SSG. It's ideal for marketing sites, blogs, and documentation where content doesn't change per user. Combine with SSR or ISR for hybrid approaches.
