Established

Converts OpenAPI specifications to Protocol Buffer binary format, enabling type-safe API tooling across languages through automatically-generated data structures. Uses a plugin architecture modeled on protoc for extensibility, with built-in support for generating clients, gRPC services, and API metrics. Parses JSON/YAML OpenAPI documents, validates dependencies, and outputs portable protobuf representations that can be consumed by any protobuf-supporting language.
