1. Docusaurus — Docs-as-code for product and developer documentation, versioned in Git.
Meta's static site generator for product and developer docs.
Strengths
- Purpose-built for versioned product docs.
- MDX lets you mix React components into content.

- Search requires Algolia or a DIY index for big sites.
- Upgrades between major versions can break custom themes.
