openapi-generator
OpenAPI Generator allows generation of API client libraries (SDK generation), server stubs, documentation and configuration automatically given an OpenAPI Spec (v2, v3)
The beta version was able to generate the expected Quote model object, but I ran into issues trying to generate an interface or abstract class that my controllers could extend. So I decided to create an issue in the openapi-generator library (link for those who are interested in the details) and pivot toward another approach.

In fact, there are a few. For instance, Telosys (that we also covered here). But Telosys defines itself as a "lightweight and pragmatic code generator", not as a low-code tool. Once again, the diverse terminology in our area makes a small domain even smaller and hides useful tools from potential users that are using the "wrong" keywords. To read mode about the relationship between the low-code and model-driven communities, take a look at our work on a Metascience Study of the Adoption of Low-Code terminology in Modeling Publications, which we are now updating and extending as I still believe it's an important discussion to have in our community.
