What each one is
The product in its own terms, so the numbers below have context.
Swagger UI
Swagger UI is a web-based tool that automatically generates interactive API documentation from OpenAPI definitions. It enables developers to visualize, test, and explore APIs with real-time validation and supports collaboration across teams through version control integration.
Thunder Client
A lightweight API testing client for VS Code and JetBrains IDEs that stores all data locally on developers' machines and enables team collaboration through Git-based synchronization without requiring context-switching to external tools.
