## Introduction

CEF Python is an open source project founded by

[Czarek Tomczak](https://www.linkedin.com/in/czarektomczak/)

in 2012 to provide Python bindings for the

[Chromium Embedded Framework](https://bitbucket.org/chromiumembedded/cef) (CEF).

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](http://en.wikipedia.org/wiki/Chromium_Embedded_Framework#Applications_using_CEF)

installed around the world. There are numerous use cases for CEF:

1. Use it as a modern HTML5 based rendering engine that can act as

   a replacement for classic desktop GUI frameworks. Think of it as Electron

   for Python.

2. Embed a web browser widget in a classic Qt / GTK / wxPython desktop

   application

3. Render web content off-screen in applications that use custom drawing

   frameworks

4. Use it for automated testing of web applications with more advanced

   capabilities than Selenium web browser automation due to CEF low level

   programming APIs

5. Use it for web scraping, as a web crawler or other kind of internet bots

CEF Python also provides examples of embedding CEF for many Python GUI

frameworks such as PyQt, wxPython, PyGTK, PyGObject, Tkinter, Kivy, Panda3D,

PyGame, PyOpenGL, PyWin32, PySide and PySDL2.

## Seeking new sponsors

CEF Python is seeking companies to sponsor further development of the project.

There are many proposals for new features submitted in the issue tracker. Most

notable are:

* Monthly releases with latest Chromium

* An automated build system similar to upstream CEF Spotify Automated Builds

* ARM and Android support

* Multi-threaded support for increased performance

* Proprietary codecs support in build tools: H264, H265,AC3, EAC3, MPEG-4

* More CEF API exposed, only about 50% is exposed so far

* Hundreds of new settings and Chromium preferences not yet exposed

* Easier integration with popular GUI toolkits in just a few lines of code

  and support for more third party GUI frameworks

* More examples of implementing various advanced features and more snippets

  as well

If your company would like to sponsor CEF Python development efforts then

please contact

[Czarek](https://www.linkedin.com/in/czarektomczak/).

Long term sponsorships are welcome and Czarek is open to ideas about

the project. He would love to spend more time on developing this project,

but he can't afford doing so in his free time. Currently there is no company

supporting this project actively on a daily basis.
