cdd-kotlin is a bidirectional compiler that converts between OpenAPI specifications and native Kotlin code (models, routes, SDKs, and CLIs) using AST and static analysis. It supports OpenAPI 3.2.0 spec compliance.
- Generate an installable Kotlin SDK from an OpenAPI spec.
- Generate a fully-typed SDK CLI with nested commands and help documentation from an OpenAPI spec.
- Scaffold a server.
- Extract an OpenAPI spec from an existing Kotlin codebase or a generated SDK CLI (full editability!).
- JSON-RPC server integration.
- Supports WASM compilation.
