Static Site Generation (SSG) is a web development approach where web pages are pre-built into static HTML files before being served to users. This means that the content is generated at build time rather than on-the-fly, resulting in faster load times and improved performance. SSG is often used for blogs, documentation sites, and portfolios. Popular tools for SSG include Gatsby, Jekyll, and Hugo. These tools allow developers to create templates and manage content easily, often using Markdown for writing. Since static sites do not rely on databases or server-side processing, they are generally more secure and easier to host.
