Swagger UI

Swagger UI is the default - but if you've outgrown its dated console and OpenAPI-only limits, here's the upgrade.

Get started

Swagger UI is fine as the bundled default. Move to Apiboost Spec Renderer when you want polished, themeable, multi-spec docs - not just the auto-generated OpenAPI page.

What they do well

Swagger UI is ubiquitous and reliable - bundled into countless frameworks, zero-config for OpenAPI, and the tool most developers already know. For a quick internal OpenAPI reference, it's the path of least resistance.

Where Apiboost Spec Renderer wins

Polished, themeable docs - 70+ design tokens vs a dated, hard-to-brand console | Multi-spec - AsyncAPI free, plus GraphQL/SOAP/gRPC in Pro | Modern UX - reference layout, search, deep-linking, custom sidebar nav
