Could you build this?
Partial A single parser or doc UI is straightforward, but building a production-grade multi-protocol compiler across OpenAPI, AsyncAPI, GraphQL, gRPC, and OpenRPC that outputs idiomatic SDKs in 11 languages requires extensive compiler/codegen expertise.
What it would actually take: The system requires an AST-based intermediate representation layer that normalizes schemas from GraphQL, protobuf/gRPC, and OpenAPI/AsyncAPI specifications. From this AST, it must run sophisticated template engines (e.g., EJS/Handlebars or custom code generators) tailored to 11 programming languages' idioms, package managers, type systems, and async runtimes. Maintaining high-fidelity typing and error-free code generation across varying language paradigms demands deep multi-language systems expertise.
