What do people build with it?

USE CASE 1

Self-host the GitBook rendering layer to apply custom styling that fully integrates your documentation into your own product's design.

USE CASE 2

Run the engine locally and point it at any public GitBook space to preview and test UI or layout changes before contributing them.

USE CASE 3

Deploy your own instance of the frontend to control the appearance and behavior of your team's documentation pages independently.

Requires Bun as the runtime and a GitBook account or public space URL to point the engine at content.

Free to use and modify, but if you distribute a modified version you must also publish its source code under the same GPL license.

In plain English

This repository contains the open-source frontend rendering engine used to display GitBook documentation sites. GitBook is a platform where teams write and publish technical documentation, this code is specifically the part that takes content stored in GitBook and renders it as a public-facing website that readers see in their browser. The rendering engine is built on Next.js (a framework for building web applications with React) and TypeScript. It fetches content from the GitBook platform and turns it into HTML pages, handling things like navigation, page layout, search, and translations for the interface text. There are two main reasons someone would use this repository. First, contributors who want to improve the appearance or fix bugs in how GitBook sites are displayed can run this locally and point it at any publicly published GitBook space to see their changes in real time. Second, teams who want to self-host the rendering layer, for example to apply custom styling that fully integrates their documentation into their own product, can deploy this separately, though the team cautions that self-hosting means taking responsibility for keeping it updated. The license is GNU GPLv3, which means if you distribute a modified version, you must also make the source code public. A commercial license is available for those who need a private fork. The project uses Bun as its package manager and runtime environment.

Copy-paste prompts

Prompt 1

I'm running the GitBook rendering engine locally with Bun. How do I point it at my own published GitBook space to see a live preview?

Prompt 2

I want to override the default page layout styles in my self-hosted GitBook frontend. Where are the layout components defined and how do I customize them?

Prompt 3

Deploy the GitBook rendering engine to a VPS with a custom domain and configure it to serve my GitBook space's content.

Prompt 4

Add a custom navigation sidebar component to my GitBook frontend fork without breaking the existing routing or search functionality.
