Choosing a site generator
Jekyll and Hugo turn content and templates into static pages. Astro suits content-driven sites that also need component-based layouts. Docusaurus and VuePress focus on documentation. Gatsby, Next.js, and Nuxt are broader frameworks with options for generating static pages.
Decide first whether the site is a blog, documentation set, or application. Then compare the editing workflow, build process, deployment target, and whether any pages need server-side behavior. A simple static site rarely needs the full complexity of an application framework.
