Introduction

CEF Python is an open source project founded by Czarek Tomczak in 2012 to provide Python bindings for the Chromium Embedded Framework (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 installed around the world. There are numerous use cases for CEF:

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.
Embed a web browser widget in a classic Qt / GTK / wxPython desktop application
Render web content off-screen in applications that use custom drawing frameworks
Use it for automated testing of web applications with more advanced capabilities than Selenium web browser automation due to CEF low level programming APIs
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.

Install

This branch targets CEF 154 (Chromium 154) and Python 3.12+. Packages for it are not yet published on PyPI, see the Build instructions to build and install the wheel.

The last release on PyPI is v66.1 for older Python versions:

pip install cefpython3==66.1

Below is a table with supported platforms, python versions and architectures.

OS	Py3	32bit	64bit	Status
Linux	3.12 / 3.13 / 3.14	No	Yes	Tested with CEF 154 on Ubuntu 24.04 (X11)
Windows	3.12 / 3.13 / 3.14	-	Yes	Not yet ported to CEF 154 (upstream tested CEF 123)
Mac	3.12 / 3.13 / 3.14	No	Yes	Tested with CEF 154 on macOS 27 (arm64)

Seeking sponsors

CEF Python is seeking companies to sponsor development of this project. Most important thing would be to have continuous monthly releases with updates to latest Chromium. There is also lots of cool features and new settings that would be nice to implement. We have not yet exposed all of upstream CEF APIs. If your company would like to sponsor CEF Python development efforts then please contact Czarek. There are no active sponsors at this moment.
