Proto Plus for Python

|pypi| |release level|

Beautiful, Pythonic protocol buffers.

This is a wrapper around protocol buffers_. Protocol buffers is a specification format for APIs, such as those inside Google. This library provides protocol buffer message classes and objects that largely behave like native Python types.

AI interpretation — verify before relying

AI-generated interpretation of the package facts above; every digit, version, license, or vulnerability id it cites is grounded in the facts already shown on this page

proto-plus wraps protocol buffers to provide Pythonic message classes that behave like native Python types, making it easier to work with Google's protocol buffer format in Python applications.

Installation is straightforward with low friction—the package is a pure Python wheel with only protobuf as a runtime dependency. Maintenance is active, with a release 7 days old and the last commit dated 2026-08-13, indicating ongoing support.

Licensed under Apache 2.0 (permissive), which allows broad use including in commercial and proprietary projects, with minimal restrictions beyond attribution and liability disclaimers.

Usage

pip install proto-plus

from proto.message import Message
from protobuf import StringValue

class HelloRequest(Message):
    name = StringValue()

Requires Python 3.10 or later; protobuf must be installed as a runtime dependency.

Verdict: proto-plus is a well-maintained, production-stable library (Development Status 5) in the top 1000 PyPI packages with no known vulnerabilities. Its permissive Apache 2.0 license and low install friction make it a reliable choice for Pythonic protocol buffer integration in Google Cloud and other protobuf-based projects.
