# pyobjc-framework-NetworkExtension — Wrappers for the framework NetworkExtension on macOS

License: permissive · Maintenance: active · Downloads: 655.9K/mo

## What it is and what it does

This package wraps Apple's NetworkExtension framework for use in Python on macOS, allowing developers to programmatically interact with system-level network configuration and extension capabilities. It is part of the PyObjC project and provides direct access to Objective-C classes and methods from the NetworkExtension framework, translated into Python idioms.

The package does not include its own documentation; users must refer to Apple's official NetworkExtension documentation and PyObjC's general translation guidelines. It depends on pyobjc-core and pyobjc-framework-Cocoa and is distributed as platform-specific wheels for macOS. The package supports Python 3.10 through 3.15, including free-threading builds, and is actively maintained.

Use it for:

- Build macOS VPN client applications or network extension tools that require direct access to system network APIs.
- Develop network monitoring or packet inspection utilities on macOS using Python.
- Create DNS or content-filtering extensions for macOS that integrate with the system network stack.
- Automate network configuration tasks on macOS that require Objective-C framework access.

## Worth the install?

AI-flagged interpretation of the facts above — verify before relying.

Provides Python bindings to Apple's NetworkExtension framework, enabling macOS applications to interact with network configuration and extension APIs at the system level.

Yes, if you are developing a macOS application that needs system-level network control and are comfortable reading Apple's framework documentation and PyObjC's translation patterns. No, if you need cross-platform network APIs or prefer pure-Python solutions. The package is stable and actively maintained, but its utility is narrowly scoped to macOS and requires familiarity with both Objective-C concepts and PyObjC's bridge semantics.

## Install

pip install pyobjc-framework-networkextension
uv add pyobjc-framework-networkextension
poetry add pyobjc-framework-networkextension

## Installing pyobjc-framework-NetworkExtension

Before you install: Medium friction: platform-specific wheels for macOS only (requires Python 3.10+), with compiled dependencies on pyobjc-core and pyobjc-framework-Cocoa. Recently maintained (last commit 2026-08-14, release 3 days old) and marked stable.

License in practice: MIT license permits commercial and private use with minimal restrictions—suitable for most projects.

Quickstart:

pip install pyobjc-framework-networkextension
import NetworkExtension
# Access NetworkExtension framework classes and methods via the imported module

macOS only; requires Python 3.10 or later and a working Objective-C bridge (pyobjc-core and pyobjc-framework-Cocoa).

Verify before relying:

- Whether the package includes type stubs or runtime type hints for IDE support.
- Specific NetworkExtension APIs covered (e.g., VPN, DNS, content filtering, packet tunneling).
- Performance or memory overhead of the Python-to-Objective-C bridge for high-frequency operations.
