What is Swagger UI?

Swagger UI is an open-source tool that provides a web-based interface for visualizing and interacting with APIs defined using the OpenAPI Specification (formerly known as the Swagger Specification). It renders the API documentation in an interactive and human-readable format, allowing developers to explore endpoints, understand request/response structures, and even execute API calls directly from the browser. It's commonly used to improve API discoverability, facilitate testing, and streamline the API development workflow.
