I'm building docs from OpenAPI and need search, auth, and examples, what should I use?

If you want to generate developer docs from OpenAPI with search, auth, and examples, a good fit is usually:

Best all-around choice: Redocly

Why it’s strong:

• Great OpenAPI rendering
• Built-in search
• Supports auth flows in API docs
• Good support for examples
• Can work as a documentation platform or a self-hosted docs site
• More customizable and scalable than basic static doc generators

Good alternatives depending on your setup

Stoplight

Best if you want:

• A polished API portal
• Strong API design + docs workflow
• Easy example management
• Collaboration features

Swagger UI

Best if you want:

• Simple, familiar OpenAPI rendering
• Built-in “Try it out” auth support
• Easy setup

Limitations:

• Search and broader docs-site features are weaker unless you build around it

Docusaurus + OpenAPI plugin / custom setup

Best if you want:

• Full control over your docs site
• Search across docs + guides + API reference
• Custom auth/example handling

Downside:

• More setup and maintenance

My recommendation

• If you want the fastest path to polished API docs: Redocly
• If you want a docs portal with collaboration/design tools: Stoplight
• If you want maximum control: Docusaurus + OpenAPI integration

If you tell me your stack:

• static vs hosted,
• public vs private docs,
• and whether you need interactive “try it” auth or just docs,

I can suggest the best exact toolchain.
