Swagger UI
Visualize and interact with the API's resources without having any of the implementation logic in place.
Overview
Swagger UI is one of the most well-known open-source tools for generating interactive API documentation from an OpenAPI (formerly Swagger) Specification. It allows developers and non-developers to interact with the API's endpoints in a sandbox environment. It's highly customizable and can be hosted anywhere.
