Mintlify is too limited for private docs

Got it — if Mintlify feels too limited for private docs, there are a few strong alternatives depending on what you need:

Good private-docs alternatives

• GitBook — polished UI, permissions, internal knowledge base features.
• Confluence — strong for team documentation, permissions, and enterprise workflows.
• Notion — flexible and easy for internal docs, though less “docs-site” oriented.
• Docusaurus / Nextra / Docsify — if you want a docs site with full control and can self-host.
• ReadMe — great for API docs, developer portals, auth, and private docs.
• MkDocs + Material — excellent if you want simple, self-hosted, markdown-based private docs.
• Outline — very good for internal documentation and collaboration.

If your main issue is privacy/access control

You probably want to check for:

• SSO / SAML support
• role-based access control
• guest permissions
• audit logs
• self-hosting or private deployment
• fine-grained page/section permissions

Quick recommendation

• Internal team docs: Outline or Confluence
• Private developer portal / API docs: ReadMe
• Self-hosted markdown docs: MkDocs Material or Docusaurus
• All-around polished docs with access control: GitBook
