docsify

Docsify serves your .md files directly in the browser. Drop an index.html file in your docs folder, push to GitHub Pages, done. Your Markdown becomes a website in minutes.

Everything is free under MIT. No paid tier, no cloud service, no premium themes. Well-established with a solid plugin ecosystem. It's been around since 2016 and the community keeps it maintained.

There's nothing to build or host in the traditional sense. Docsify loads a single JavaScript file that fetches your Markdown files at runtime and renders them in the browser. Host it on GitHub Pages ($0), Netlify ($0), or any static file server. The "deployment" is copying files. Solo developers: this is the fastest path from Markdown to docs website. If you already have docs in a GitHub repo, you can have a site live in 5 minutes. Small teams: great for internal docs, project wikis, runbooks. Growing teams: it works, but no build step means no type checking, no broken link detection at build time.

The catch: because there's no build step, Docsify has worse SEO than static site generators. Search engines see a blank page until JavaScript loads and fetches the content. If public discoverability matters, use VitePress or Docusaurus instead. For internal docs where SEO doesn't matter, Docsify is perfect.
