Read 2026-11-05. Source: https://agentreadyhtml.com/vendors/vitepress/ Site: Agent Ready HTML Last reviewed: 2026-11-05 # VitePress: vendor profile In short VitePress pre-renders each Markdown page to HTML and writes a root 404.html that, since version 1.2.1, renders on the client and holds almost no text. llms.txt and .md copies come from a community plugin, not core. vitepress.dev answered Accept: text/markdown with HTML on 2026-11-05. ## At a glance **standards.txt** vitepress ```text llms-txt = partial markdown-negotiation = no statement markdown-twin = partial initial-html = supports real-404 = supports vary-accept = no statement ``` 2 supports, 2 partial or announced, 2 no statement. **VitePress** Framework Vite and Vue static site generator that pre-renders each Markdown page to HTML and writes a root 404.html; sitemap.xml needs a hostname, and llms.txt or .md twins come only from the community vitepress-plugin-llms. Type [Framework](https://agentreadyhtml.com/vendors/by-type/framework/) Operator, as the facts below state it Vue.js project (vuejs organization on GitHub) Home page [vitepress.dev](https://vitepress.dev/), answered HTTP 200 on 2026-11-05 Last read 5 November 2026 ## What it does for this layer - VitePress takes Markdown source, applies a theme and writes static HTML pages, so page text is in the HTML file an agent fetches. \[primary source\] [source](https://vitepress.dev/guide/what-is-vitepress), read 5 November 2026. - On a first visit VitePress serves the pre-rendered HTML, then loads a JavaScript bundle that hydrates the page into a Vue single page app for later navigation. \[primary source\] [source](https://vitepress.dev/guide/what-is-vitepress), read 5 November 2026. - The VitePress deploy guide says 404.html is generated for the root depth only, and hosts that serve that file for deep missing URLs render it without styles. \[primary source\] [source](https://vitepress.dev/guide/deploy), read 5 November 2026. - VitePress 1.2.1 (2024-05-21) changed the 404 page to render completely on the client so the locale can be read from the browser path, which keeps its 404.html nearly empty of text. \[primary source, 2024-05-21\] [source](https://raw.githubusercontent.com/vuejs/vitepress/main/CHANGELOG.md), read 5 November 2026. - VitePress writes sitemap.xml only after sitemap.hostname is set in .vitepress/config, and adds lastmod tags when the lastUpdated option is on. \[primary source\] [source](https://vitepress.dev/guide/sitemap-generation), read 5 November 2026. - The VitePress default theme gets fuzzy full-text search from an in-browser MiniSearch index when themeConfig.search.provider is 'local'; Algolia DocSearch is the hosted alternative. \[primary source\] [source](https://vitepress.dev/reference/default-theme-search), read 5 November 2026. - The experimental mpa option builds a VitePress site in MPA mode, shipping 0 kB of JavaScript by default and dropping client-side navigation. \[primary source\] [source](https://vitepress.dev/reference/site-config), read 5 November 2026. - VitePress has no structured data setting; its transformHead build hook returns extra head tags per page, which is where a site would add JSON-LD. \[primary source\] [source](https://vitepress.dev/reference/site-config), read 5 November 2026. - With the cleanUrls option VitePress generates links without the .html extension, which needs a host that serves /foo.html for /foo. \[primary source\] [source](https://vitepress.dev/guide/routing), read 5 November 2026. - The config of vitepress.dev imports the community package vitepress-plugin-llms and calls llmstxt with workDir 'en' only in production builds. \[primary source\] [source](https://raw.githubusercontent.com/vuejs/vitepress/main/docs/.vitepress/config.ts), read 5 November 2026. - vitepress.dev served a text/markdown twin at /guide/getting-started.md (6,275 bytes) on 2026-11-05, yet the same page requested with Accept: text/markdown came back as 56,191 bytes of HTML with only Vary: Accept-Encoding. \[observed\] [source](https://vitepress.dev/guide/getting-started), read 5 November 2026. - The VitePress changelog dates 2.0.0-alpha.21 to 2026-10-25, a pre-release that adds asset sharding and native RTL support in the theme. \[primary source, 2026-10-25\] [source](https://raw.githubusercontent.com/vuejs/vitepress/main/CHANGELOG.md), read 5 November 2026. - VitePress ships under the MIT License with copyright held by Yuxi (Evan) You since 2019. \[primary source\] [source](https://raw.githubusercontent.com/vuejs/vitepress/main/LICENSE), read 5 November 2026. ## Test build - A default VitePress 1.6.4 site (npm add -D vitepress@1.6.4, npx vitepress init with every default, npm run docs:build) built on 2026-11-05 held 404.html and three page files but no llms.txt, robots.txt or sitemap.xml. \[observed\] [source](https://vitepress.dev/guide/getting-started), read 5 November 2026. - Under vitepress preview that 1.6.4 build kept the hero H1 'My Awesome Project' in the server HTML, answered a made-up path with 404, and returned text/html to Accept: text/markdown. \[observed\] [source](https://vitepress.dev/guide/getting-started), read 5 November 2026. ## Products and plans | Product | What it is | Price | As of | Source | | --- | --- | --- | --- | --- | | VitePress | Static site generator and default docs theme built on Vite and Vue. | Free, open source;
