Postman vs Swagger UI

What each one is
The product in its own terms, so the numbers below have context.
Postman
Postman is a comprehensive platform that simplifies the API lifecycle by providing tools for designing, testing, and collaborating on APIs. It helps teams build and maintain APIs more efficiently.
Swagger UI
A tool that automatically transforms OpenAPI specifications into visual, interactive documentation allowing developers to explore and test API operations directly without implementing the backend. Works across browsers and deployment environments as a set of reusable web components.
