Gatsby

Gatsby is an open-source, React-based framework for building high-performance websites and applications. It leverages a modern web stack, including React and GraphQL, to enable developers to create dynamic experiences while benefiting from the speed and scalability of static site generation (SSG), deferred static generation (DSG), and server-side rendering (SSR). Gatsby pulls data from various sources—such as Markdown files, headless CMS platforms (like Contentful or WordPress), or REST/GraphQL APIs—through a unified GraphQL data layer. It automates critical performance optimizations, including code splitting, image optimization, and lazy-loading, to ensure fast loading times by default. The current stable version is 5.16.1, with frequent patch and minor releases addressing bug fixes, dependency updates, and compatibility with new Node.js and React versions. Its key differentiators include a rich plugin ecosystem, built-in performance tooling, and granular control over rendering options on a per-page basis.
