# PyQtWebEngine-Qt5 — The subset of a Qt installation needed by PyQtWebEngine.

License: copyleft · Maintenance: active · Downloads: 286.2K/mo

## What it is and what it does

pyqtwebengine-qt5 is a binary distribution of Qt5 libraries needed to run web engine applications. It is not typically installed directly; instead, it is pulled in automatically when you install the parent package via pip. The package contains precompiled Qt5 binaries for web rendering and GUI components, eliminating the need to build Qt5 from source or install it system-wide.

This is a dependency-only package with no Python runtime dependencies of its own. It exists to simplify installation by bundling necessary Qt5 runtime, reducing setup friction and platform-specific build complexity. The package is actively maintained and carries no known security vulnerabilities.

Use it for:

- Installing web engine applications without requiring a system Qt5 installation or build tools
- Distributing desktop applications with bundled Qt5 libraries on macOS and Linux
- Running applications on macOS (both Intel and Apple Silicon) or Linux without manual Qt5 setup
- Simplifying CI/CD pipelines by avoiding system library dependencies

## Worth the install?

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

Provides the Qt5 runtime libraries required by web engine bindings, typically installed automatically as a dependency when you install the parent package.

Yes, if you are using the parent package. This package is almost always installed automatically as a dependency and requires no direct action. It is actively maintained, carries no known vulnerabilities, and has medium install friction only due to platform-specific wheels—a reasonable trade-off for avoiding manual Qt5 compilation. The LGPL v3 copyleft license is standard for Qt and should be factored into your application's license compliance strategy.

## Install

pip install pyqtwebengine-qt5
uv add pyqtwebengine-qt5
poetry add pyqtwebengine-qt5

## Installing PyQtWebEngine-Qt5

Before you install: Medium install friction due to platform-specific pre-built wheels for macOS x86_64, macOS ARM64, and Linux x86_64. Actively maintained with a release 85 days ago.

License in practice: Licensed under LGPL v3 (copyleft). Applications using this library 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 pyqtwebengine-qt5==5.15.19

Platform-specific wheels available for macOS (x86_64, ARM64) and Linux x86_64; other platforms may not be supported.

Verify before relying:

- Whether this package can be installed standalone or only as a transitive dependency
- Full list of supported platforms beyond the three wheel distributions listed
- Minimum Python version requirement (not specified in metadata)
