Swagger UI
In plain terms
An interactive interface for exploring REST APIs.
Going deeper
Swagger UI renders an OpenAPI spec into browsable, try-it-out documentation so users can call endpoints directly. It turns specs into living docs.
Under the hood
Auto-generated from OpenAPI; lets developers test endpoints without writing client code.
Examples
API documentation, interactive docs, OpenAPI, try-it-out consoles, developer portals.
Think of it like...
Like an interactive product manual with working buttons for every feature.
