Hub turns Markdown files into a full-featured documentation site — with dark/light themes, full-text search, interactive React components embedded right in your .md files, sortable tables, syntax highlighting, and mobile-first navigation. No database, no CMS, no lock-in. Drop a file in Docs/, run generate, done. Built on Astro + React, XSS-sanitized via DOMPurify, audited by SonarCloud. Fully open-source under Apache 2.0 — fork it, brand it, ship your own Hub.
