Documentation you own end to end

Duvlify is an open-source Astro framework for documentation sites. Write Markdown, get a fast static site with search, an API reference, and an MCP server for AI agents.

Duvlify is an open-source framework for documentation sites. You write your pages in Markdown. Duvlify builds a fast, static website from them, with search, an API reference, and a server that lets AI agents read your docs.

No hosted service sits between you and your site. No per-seat fee. No app framework loads in the visitor’s browser. The output is plain HTML files, and you own every one of them.

Get started

Clone it, run one command, and see your site.

Write a page

Add frontmatter to a Markdown file. Its path becomes its URL.

Serve AI agents

One endpoint turns your docs into tools an agent can call.

Deploy it

Ship it on Cloudflare, or on any static host you already use.

Why teams pick Duvlify

You own the output

Plain HTML files. Move them to any host at any time.

Nothing to pay per seat

Free and open source, under the MIT licence.

Built to be checked

A broken link or a bad field stops the build and names the file.

See the full list of reasons, and the use cases Duvlify fits, on the Why Duvlify page.

Start in one command

npmgit clone https://github.com/DuvInc/duvlify.git && cd duvlify
npm install && npm run dev

pnpmgit clone https://github.com/DuvInc/duvlify.git && cd duvlify
pnpm install && pnpm dev

A fresh clone runs with no setup. Search works. The agent tools answer. The build passes. Every optional service starts switched off, so you do not need an account to see your first page.

One file controls the site

A page states what it is: its title, its description, its icon. The file src/docs.config.ts states where that page sits in the navigation. Duvlify joins the two at build time. The sidebar, the tabs, the search index, and the agent tools all read that one result.

src/docs.config.tsexport const navigation: NavTab[] = [
  {
    id: 'guides',
    label: 'Guides',
    icon: 'rocket',
    groups: [
      { label: 'Start here', icon: 'zap', pages: ['getting-started', 'guides/authoring'] },
    ],
  },
];

Nothing here repeats a page’s own frontmatter. If a listed page does not exist, or a page exists in no group, the build stops and tells you which one.

Built for people and for AI agents

A person reads a web page. A search engine wants one clear page per topic. An AI agent wants plain Markdown, a map of your docs, and permission to read them.

Duvlify serves all three from one build. Add .md to any page URL to get that page as plain text, or ask for it with the header Accept: text/markdown.
