I've been using openapi-generator for this for quite some time. I love the principle, but find that their generators are not all top notch, and the template-based approach is very hard to contribute to.

One thing I do not see with Stainless is also using it to generate the server side of the API.

We use OpenAPI as a design doc, and generate client SDKs and Datos for the server from the same spec. This gives us pretty solid control over interoperability.

Thats what I used at my previous startup and had a lot of luck with it. Our backend used NestJS which allowed us to define APIs and DTOs using decorators which automatically generated OpenAPI json files. Then our clients would load the json and generate their own SDK as a library. It worked extremely well. It worked so well that I don't really understand what problem Stainless is solving. We didn't ship public SDKs. So, maybe that's what I'm missing, but for our internal clients OpenAPI generators worked great. We generated SDKs on the fly for TypeScript (Node services and Angular clients), Dart (flutter), Kotlin (android), and Swift (iOS). For the most part it all "just worked" for our use case.
