A Static Site Generator (SSG) is a software application that creates HTML pages from templates or components and raw data, typically stored in files rather than databases. Each page is represented as a file on the web server and served to users just as it is stored, without any server-side processing.
Examples of SSGs include Jekyll, Hugo, and Gatsby. They are typically used for blogs and documentation websites with simple structures and no user interactivity. SSGs offer several advantages such as enhanced performance, security, and ease of deployment.
However, they may not be suitable for applications that require server-side functionalities, such as user authentication, real-time updates, or complex querying capabilities.
