A Python code generator and runtime library for Protobuf 3 and async gRPC that produces idiomatic, typed, dataclass-based Python code. It serves as a modern alternative to the official Google protoc Python plugin, with built-in binary/JSON serialization and async/await support.

Use cases

• generate idiomatic python code from protobuf definitions
• async grpc client and server in python
• serialize protobuf messages to binary and json
• generate pydantic models from proto files
• replace official google protobuf python codegen
• type-checked protobuf stubs with mypy support

When to choose

• you want modern, readable, typed Python code from .proto files
• you need async/await gRPC support out of the box
• you want built-in JSON serialization and pydantic model generation

When to avoid

• you need Protobuf 2 or legacy feature support
• you require a strict drop-in replacement for the official protobuf runtime
• you want the most actively developed version - the project has moved to betterproto2
