Swagger UI

Explore and test APIs interactively.

What is Swagger UI?

Swagger UI renders your OpenAPI spec as an interactive web page. Developers can browse endpoints, read schemas, and send live requests - all from the browser.

Where it lives

With the -ui starter, Swagger UI is served at /swagger-ui.html by default. It loads the spec from /v3/api-docs.

// open in a browser:
// http://localhost:8080/swagger-ui.html
