pywebview is a lightweight cross-platform wrapper around a webview component that allows to display HTML content in its own native GUI window. It gives you power of web technologies in your desktop application, eliminating the need of launching a web browser. Combined with a lightweight web framework like Flask, Bottle or web.py, you can create beautiful cross-platform HTML5 user interfaces targeting WebKit, while hiding implementation details from the end user.
pywebview is lightweight and has no dependencies on an external GUI framework. It uses native GUI for creating a web component window: Win32 on Windows, Cocoa on Mac OSX and Qt4/5 or GTK3 on Linux. If you choose to freeze your application, it does not bundle a heavy GUI toolkit with it, which keeps the executable size small. Compatible with both Python 2 and 3.

pip install pywebview
pywin32, comtypes. ActiveState distribution of Python 2 comes with pywin32 preinstalled
pyobjc. PyObjC comes presintalled with the Python bundled in OS X. For a stand-alone Python installation you have to install it separately.

PyGObject
For QT based systems
Either PyQt4 or PyQt5
import webview
webview.create_window("It works, Jim!", "http://www.flowrl.com")
For more elaborated usage, refer to the examples in the examples folder
-
webview.create_window(title, url, width=800, height=600, resizable=True, fullscreen=False)Create a new WebView window. Calling this function will block execution, so you have to execute your program logic in a separate thread. -
webview.load_url(url)Load a new URL into a previously created WebView window. This function must be invoked after WebView windows is created with create_window(). Otherwise an exception is thrown. -
webview.create_file_dialog(dialog_type=OPEN_DIALOG, allow_multiple=False)Create an open file (webview.OPEN_DIALOG) or open folder (webview.FOLDER_DIALOG) dialog.allow_multiple=Trueenables multiple selection. Return a tuple of selected files, None if cancelled
For OS X and Linux systems you get WebKit. The actual version depends on the version of installed Safari on OS X and QT / GTK on Linux. Note that WebKit bundled with QT / GTK is slightly out of date comparing to the latest Safari or Chrome.
For Windows, you get, well, MSHTML (Trident) in all its glory. The version depends on the installed version of Internet Explorer. By default, when creating an embedded web component, MSHTML uses IE7 rendering mode. To overcome this feature, a registry setting is modified to use the latest installed version of Internet Explorer. Note that for Windows XP systems, you cannot get anything better than IE8. For Vista, you are limited to IE9.
Support for Chromium Embedded Framework (CEF) is planned for future versions. Help with embedding CEF is welcomed.
Web renderer might cache your code and fail to invalidate it, when it is updated. To prevent that add the following directives to the <HEAD> of your HTML files
<meta http-equiv="pragma" content="no-cache">
<meta http-equiv="cache-control" content="no-cache">
<meta http-equiv="expires" content="-1">
Use py2app on OS X and py2exe on Windows. For reference setup.py files, look in examples/py2app_setup.py and examples\py2exe_setup.py
