AutoRest: OpenAPI Specification code generator 9 years ago
I asked the HN community for feedback on using Swagger Codegen, AutoRest last year: https://news.ycombinator.com/item?id=12485310
They're essentially the same but written in different languages (Java vs C#/TypeScript).
Eventually we picked Swagger Codegen due to its active community and wide-range of supported languages/frameworks.
