No, we built our first code generator from scratch in 2014 [1]. I don't think most of these projects existed at the time. Our current CodeGen has always been written-from-scratch, propriety code. Our focus is also a bit different from these projects: we aim to cover as much of the OpenAPI format feature-set while generating consistent, high-quality, well-designed SDKs (should be as good as a good engineer can produce). To complete the Developer Experience of the API, we also generate complete API documentation site as well [4].
Back in 2014, OpenAPI didn't even exist. The latest API specification format was Swagger 1.2 and it was not very mature at that point. We had to build a lot of vendor extensions to cover the various REST API use-cases that API folks take for granted today.
Today, we also run the most-used API Spec format convertor tool in the world by the name of API Transformer [2]; this tool has helped a lot of companies migrate from an older spec formats like OpenAPI 2 and RAML to OpenAPI 3. We support nearly all API specification formats including RAML, OpenAPI (2., 3.), Blueprint, Postman, WADL and more.[3]
