CEF Python is a BSD-licensed open source project founded by Czarek Tomczak (hire me!) in 2012 and is based on Google Chromium and the CEF Framework projects. The Chromium project focuses mainly on Google Chrome application development, while CEF focuses on facilitating embedded browser use cases in third-party applications. Lots of applications use CEF control, there are more than 100 million CEF instances installed around the world. Examples of embedding Chrome browser are available for many popular GUI toolkits including: wxPython, PyGTK, PyQt, PySide, Kivy, Panda3D and PyGame/PyOpenGL.
There are many use cases for CEF. You can embed a web browser control based on Chromium with great HTML 5 support. You can use it to create a HTML 5 based GUI in an application, this can act as a replacement for standard GUI toolkits such as wxWidgets, Qt or GTK. In such case to communicate between Python<>Javascript use javascript bindings or embed an internal web server and talk using http requests. You can render web content off-screen in applications that use custom drawing frameworks. You can use it for automated testing of existing applications. You can use it for web scraping or as a web crawler, or other kind of internet bots.
