Swagger UI

Swagger UI is an open-source tool that provides a user-friendly interface for visualizing and interacting with APIs. It automatically generates interactive API documentation from OpenAPI specifications, allowing developers and users to explore API endpoints, parameters, and responses directly within a web browser. This facilitates a better understanding of the API's functionality and streamlines the development and integration processes.
