## What it is
The open source frontend that renders GitBook's published documentation sites, built in TypeScript and runnable locally with Node.js and Bun. It lets you serve any published GitBook space through a local development server.

## Use cases
- self-host a GitBook documentation site
- render published GitBook spaces locally
- customize the look and behavior of GitBook doc sites
- contribute to the GitBook docs rendering frontend
- preview GitBook content before publishing

## When to choose
- you publish docs on GitBook and want control over the rendering frontend
- you want to self-host or customize how GitBook sites are served
- you want to contribute to GitBook's open source docs renderer

## When to avoid
- you need the full GitBook authoring/editing platform, which is a commercial product
- you want a general-purpose static site generator for arbitrary Markdown sites
- you expect the legacy gitbook CLI (npm gitbook package) - that is a separate deprecated tool

## Facets
- artifact type: application
- maturity: active
- function: documentation, static-site-generator, markdown, http-server, search-engine
- domain: documentation, web-development, developer-tools
