ReDoc Interactive Demo

ReDoc focuses on simplicity and readability, presenting the API documentation in a user-friendly format. It supports dark mode, multiple languages, and offers a seamless browsing experience for API consumers.

There are a few other tools out there that are at least marginally better than the default Swagger UI such as ReDoc (https://github.com/Redocly/redoc).

When we redid the Mux docs (https://docs.mux.com/api-reference) we actually just decided to build our own renderer. It really wasn't as bad as you might think, at build time we pull in the JSON version of our OAS spec and render it as a static build in our Nextjs app. Don't get me wrong, it wasn't trivial, but the benefit of having complete control over the output has been well worth it.

ReDoc is a tool that's similar to Swagger UI. It also takes an OAS and renders an interactive HTML page with full API documentation details; however, it has a notable difference.

Redoc is an open source tool to generate API reference documentation websites from OpenAPI definitions.

FastAPI for Python has an awesome way of doing this. It comes with two choices: Swagger and Redoc, the former being more interactive while the latter is (IMO) more visually appealing. I'm sure you could implement one of these using Spring.

Starlite has substantially enhanced OpenAPI (3.1) documentation - in fact, its the most complete autogenerated schema around, and it ships with Redoc, Swagger-UI and Stoplight-Elements static sites.
