## What it is
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

## Facets
- artifact type: library
- maturity: maintenance
- function: serialization, rpc
- domain: developer-tools, apis, backend
- platform: python, cross-platform
- tags: protobuf, grpc, asyncio, dataclasses, pydantic, protoc-plugin, code-generator, code-generation
