Overall AI readiness assessment

How ready vite.dev is for AI systems

71/100

Vite was independently audited by llmsmap. vite.dev currently scores 71/100 for AI readiness. The result combines AI-specific files, crawler policy, sitemap discovery, structured homepage data, and—when available—the mobile Google Lighthouse technical profile.

Audit context

llms.txt is accessible and contains 878 tokens. No accessible llms-full.txt was detected, so deeper context still has to be assembled from regular pages. No separate ai.txt policy was detected; it is optional, but can clarify training, retrieval, and attribution preferences.

robots.txt was not found, so explicit crawler policy could not be confirmed. No Schema.org type was detected on the homepage. 6 OpenGraph tags were found and markup completeness is 60%, leaving more entity interpretation to crawlers.

The mobile Lighthouse profile adds Performance 71/100, Accessibility 96/100, Best Practices 100/100, SEO 100/100, and experimental Agentic Browsing 100/100. These signals have a limited weight: they complement rather than replace llms.txt, robots.txt, and structured-data checks.

Priority improvements

1Add llms-full.txt for richer first-party context.
2Publish robots.txt with explicit search and AI crawler rules.
3Declare the current sitemap.xml in robots.txt.
4Add JSON-LD for the organisation, website, and core entities.

Google Lighthouse technical profile

Agentic Browsing

What these results mean

Mobile performance is 71/100, with the largest visible content block appearing in 9.4 s and the browser main thread blocked for 10 ms. Layout shift was 0. The main thread is where the browser runs JavaScript, calculates layout, and paints the page; long work there delays both user input and browser-agent actions.

Accessibility scored 96/100, Best Practices 100/100, and technical SEO 100/100. The experimental Agentic Browsing category scored 100/100. It measures signals Google currently tests for software agents and is shown separately from the llmsmap AI-readiness score.

Free the main thread and accelerate the first view

Split long JavaScript tasks, defer non-critical scripts and styles, and shorten blocking request chains. This helps the primary content appear sooner and makes controls usable earlier.

Reduce code that loads without helping the page

Remove unused CSS and JavaScript, load heavy widgets on demand, and limit third-party scripts. Less code means less parsing and background work on the device.

Optimise images and their loading order

Serve correctly sized modern formats, prioritise the primary visual, and lazy-load content below the first viewport.

Reduce network delay

Improve server response time, remove unnecessary redirects and repeat downloads, and use compression, caching, and selective preconnect hints.

FCP · First content: When the first text or image appeared on screen.
LCP · Main content: When the largest visible element in the first viewport rendered.
CLS · Layout stability: How much content shifted unexpectedly while loading; lower is better.
TBT · Blocking time: How long the browser main thread could not respond quickly to input.
SI · Visual speed: How quickly the visible viewport filled with content.

# Vite

> The Build Tool for the Web

- 💡 Instant Server Start
- ⚡️ Lightning Fast HMR
- 🛠️ Rich Features
- 📦 Optimized Build
- 🔩 Universal Plugin Interface
- 🔑 Fully Typed APIs

Vite is a build tool that aims to provide a faster and leaner development experience for modern web projects. It consists of two major parts:

- A dev server that provides [rich feature enhancements](https://vite.dev/guide/features.md) over [native ES modules](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Guide/Modules), for example extremely fast [Hot Module Replacement (HMR)](https://vite.dev/guide/features.md#hot-module-replacement).

- A build command that bundles your code with [Rolldown](https://rolldown.rs), pre-configured to output highly optimized static assets for production.

In addition, Vite is highly extensible via its [Plugin API](https://vite.dev/guide/api-plugin.md) and [JavaScript API](https://vite.dev/guide/api-javascript.md) with full typing support.
