Gatsby is a React-based framework for building websites and web applications that uses GraphQL to manage data and pre-renders pages to static files for fast performance. Developers use Gatsby when they need a static site generator with built-in optimization, or when they want to build dynamic web apps with React while benefiting from server-side rendering and code splitting. It's particularly useful for blogs, documentation sites, and e-commerce applications where performance and scalability matter.
