# PyQt6-WebEngine-Qt6 — The subset of a Qt installation needed by PyQt6-WebEngine.

License: copyleft · Maintenance: active · Downloads: 252.7K/mo

## What it is and what it does

PyQt6-WebEngine-Qt6 is a binary distribution of the Qt6 libraries needed to run PyQt6-WebEngine. It bundles pre-compiled Qt6 runtime components as platform-specific wheels, eliminating the need to install Qt6 separately on your system. When installed, this package is typically pulled in automatically as a dependency, so most users never interact with it directly.

The package exists to simplify deployment: instead of requiring end-users to have Qt6 installed system-wide, applications can declare this package as a dependency and pip handles the rest. It has no runtime dependencies of its own and carries a copyleft (LGPL v3) license, which means any application using it must respect the license terms if distributed.

Use it for:

- Automatic dependency resolution when installing packages that require Qt6 runtime.
- Building applications that embed a web engine without system Qt6 dependencies.
- Packaging applications for distribution to end-users who lack Qt6.
- Development environments where system-wide Qt6 installation is not feasible or desired.

## Worth the install?

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

Provides the Qt6 runtime libraries required by PyQt6-WebEngine, bundled as a binary wheel for direct installation without needing a separate Qt installation.

Yes, but only as a transitive dependency—do not install directly unless you have a specific reason. It is actively maintained, has no known vulnerabilities, and solves a real packaging problem. The copyleft license is standard for Qt and should not be a barrier unless you are distributing proprietary software without source disclosure.

## Install

pip install pyqt6-webengine-qt6
uv add pyqt6-webengine-qt6
poetry add pyqt6-webengine-qt6

## Installing PyQt6-WebEngine-Qt6

Before you install: Medium install friction due to platform-specific binary wheels (macOS x86_64/arm64, Linux x86_64/aarch64, Windows amd64/arm64). Last release was 91 days ago with active maintenance status.

License in practice: Licensed under LGPL v3 (copyleft). Any application linking this package must comply with copyleft obligations—source code disclosure may be required if you distribute the combined work.

Quickstart:

# Typically installed automatically as a dependency:
pip install pyqt6-webengine-qt6==6.11.1

Platform-specific wheel; installation requires a compatible OS/architecture match (macOS 10.14+, Linux glibc 2.34+, or Windows).

Verify before relying:

- Whether this package can be used independently or only as a transitive dependency.
- Exact Python version compatibility (requires_python is unspecified in metadata).
- Whether Qt6 runtime is available on all declared platforms or if some wheels are stubs.
