What Is Starlight

Starlight is a documentation site framework built on Astro, created to give developers a fast path to a polished, accessible documentation website. Rather than building a docs site from scratch, teams configure Starlight and get navigation, search, theming, and internationalization by default.

Starlight is maintained by the Astro core team as an open-source project, first introduced in 2023. It has become a popular choice for open-source project documentation, developer tools, and API references because it emphasizes performance and accessibility without requiring extensive custom development.

Key Features

Starlight automatically generates site navigation from a project's folder and file structure, and includes built-in full-text search powered by Pagefind so visitors can find content without an external search service.

The framework supports Markdown, MDX, and Markdoc for content authoring, includes built-in internationalization for multilingual documentation sites, and ships dark and light theme support along with accessible typography and code syntax highlighting. Because it is built on Astro, Starlight sends minimal JavaScript to the browser, keeping documentation sites fast, and it supports framework-agnostic components so teams can embed React, Vue, Svelte, or Solid UI where interactivity is needed.

Pricing

Starlight is completely free and open source. There is no paid tier, subscription, or license fee; teams self-host the generated static site wherever they choose, such as Netlify, Vercel, or GitHub Pages.
