Middleman is a Ruby-powered static site generator that emphasizes clean templates, flexible layouts, and a great developer experience. It supports common templating languages (ERB, Haml, Slim) and content formats (Markdown, AsciiDoc), plus front-matter metadata to drive layouts, navigation, and per-page behavior. A built-in dev server with live reload keeps iteration fast, while an asset pipeline handles fingerprinting, minification, and cache-friendly builds. Extensions cover blogging, internationalization, sitemaps, data-driven pages, and external build steps, so complex sites remain manageable without server-side code. Because output is plain files, Middleman sites deploy anywhere—from object storage and CDNs to GitHub Pages—benefiting from high performance and low attack surface. Teams use it for marketing sites, docs, microsites, and prototypes where content and design matter more than dynamic backends.
