Hi, I'm Shannon, the Product Manager for Swagger Inspector. We're very excited to have launched Inspector! In particular, we think its ability to create OpenAPI Definitions will open up the ability to use a ton of useful tools, such as swagger-ui for API reference and documentation and the variety of tools like swagger-codegen that can create SDKs to increase adoption of APIs. Please feel free to send us questions and feedback!
