• Better for building a full developer experience portal

Cons

If your main goal is API reference docs

Consider how your API spec is stored:

• OpenAPI/Swagger

  • Both can work well.
  • Docusaurus often pairs with plugins or custom integrations.
  • GitBook is simpler if you want a managed experience.

• Markdown-based reference + guides

  • Docusaurus shines if you want everything in Git and versioned.
  • GitBook is easier if non-devs also edit docs frequently.

Key decision factors

Pick GitBook if:

• You want minimal setup
• You don’t want to manage infrastructure
• You need a polished UX immediately
• Your team values collaboration and simplicity

Pick Docusaurus if:

• You want self-hosting/open source
• You need deep customization
• Your docs live with your codebase
• You want to scale into a broader developer portal

My recommendation

• For a startup or team moving fast: GitBook
• For a developer platform or open-source product: Docusaurus
