Installation

pip install pywebview

This will install pywebview with default dependencies. To install pywebview with PySide2 (available on Linux and macOS and Windows) use

pip install pywebview[qt]

To install pywebview with CEF (available on Windows) use

pip install pywebview[cef]

Dependencies

Windows

pythonnet (requires > .NET 4.0)

To use with the latest Chromium you need WebView2 Runtime. If you plan to distribute your software, check out distribution guidelines too.

To use with CEF you need cefpython

pip install cefpython3

macOS

pyobjc

PyObjC comes presintalled with the Python bundled in macOS. For a stand-alone Python installation you have to install it separately. You can also use QT5 in macOS

Linux

pip install pywebview[qt] should take of QT dependencies. If it does not work or you would like to use GTK, you may try these recipes.

PyGObject is used with GTK. To install dependencies on Ubuntu for both Python 3 and 2

sudo apt install python3-gi python3-gi-cairo gir1.2-gtk-3.0 gir1.2-webkit2-4.0

For other distributions, consult the PyGObject documentation

Note that WebKit2 version 2.22 or greater is required for certain features to work correctly. If your distribution ships with an older version, you may need to install it manually from a backport.



PySide2 is used with QT. pywebview supports both QtWebChannel (newer and preferred) and QtWebKit implementations. Use QtWebChannel, unless it is not available on your system.

To install QT via pip

pip install qtpy pyside2

To install QtWebChannel on Debian-based systems (more modern, preferred)

sudo apt install python3-pyqt5 python3-pyqt5.qtwebengine python3-pyqt5.qtwebchannel libqt5webkit5-dev

To install QtWebKit (legacy, but available for more platforms).

sudo apt install python3-pyqt5 python3-pyqt5.qtwebkit python-pyqt5 python-pyqt5.qtwebkit libqt5webkit5-dev

Starting from Ubuntu Disco Dingo pywebview can be installed via apt on Debian based system as python-pywebview. This package features an old version of pywebview that is API incompatible with the current version. If you choose to install it, you can find documentation here
