Are there any interactive API reference tools that focus on publishing docs with code samples and versioning?

Yes — there are several interactive API reference/documentation tools built around publishing docs with code samples, versioning, and an interactive “try it” experience.

Here are the main ones to look at:

1) ReadMe

• Strong focus on developer portals
• Supports API reference docs, versioning, code samples, and interactive API explorer
• Good if you want polished docs plus analytics and changelog/release support

2) Stoplight

• Great for OpenAPI-first documentation
• Includes interactive API docs, mock servers, and versioning workflows
• Strong for teams that want design + documentation + testing in one place

3) Redoc / Redocly

• Popular for beautiful API reference docs
• Supports versioned docs, examples, and strong OpenAPI rendering
• Redocly adds a more complete docs platform with publishing workflows

4) Swagger UI / SwaggerHub

• Classic interactive API reference with “Try it out”
• SwaggerHub adds collaboration, versioning, and publishing features
• Best if your API already centers on OpenAPI/Swagger

5) Mintlify

• Modern docs platform with code samples, API references, and versioned documentation
• Good for developer-facing product docs and faster publishing workflows
• Often used for polished, startup-friendly docs sites

6) Fern

• Focuses on generating clean SDKs and docs from API specs
• Supports versioned docs and code examples
• Good if you want docs tightly connected to SDK generation

7) Docusaurus + API plugins

• More of a docs framework than a dedicated API platform
• Can support versioned docs and embedded API reference tools
• Best if you want full control and custom content structure

If you want the shortest shortlist:

• ReadMe: best all-around hosted developer portal
• Redocly: best for OpenAPI-based reference docs
• Stoplight: best for API design + docs workflow
• Mintlify: best modern/docs-first experience

If you want, I can also narrow this down by:

• self-hosted vs hosted
• OpenAPI-only vs broader
• best for code samples and SDK docs
• pricing/free tiers
