The Chromium Embedded Framework (CEF) is a simple framework for embedding Chromium-based browsers in other applications. It is a BSD-licensed open source project founded by Marshall Greenblatt in 2008 and based on the Google Chromium project. Unlike the Chromium project itself, which focuses mainly on Google Chrome application development, CEF focuses on facilitating embedded browser use cases in third-party applications. CEF insulates the user from the underlying Chromium and Blink code complexity by offering production-quality stable APIs, release branches tracking specific Chromium releases, and binary distributions. Most features in CEF have default implementations that provide rich functionality while requiring little or no integration work from the user. There are currently over 100 million installed instances of CEF around the world embedded in products from a wide range of companies and industries. A partial list of companies and products using CEF is available on the CEF Wikipedia page. Some use cases for CEF include:

Embedding an HTML5-compliant Web browser control in an existing native application.
Creating a light-weight native “shell” application that hosts a user interface developed primarily using Web technologies.
Rendering Web content “off-screen” in applications that have their own custom drawing frameworks.
Acting as a host for automated testing of existing Web properties and applications.

CEF supports a wide range of programming languages and operating systems and can be easily integrated into both new and existing applications. It was designed from the ground up with both performance and ease of use in mind. The base framework includes C and C++ programming interfaces exposed via native libraries that insulate the host application from Chromium and Blink implementation details. It provides close integration between the browser and the host application including support for custom plugins, protocols, jаvascript objects and jаvascript extensions. The host application can optionally control resource loading, navigation, context menus, printing and more, while taking advantage of the same performance and HTML5 technologies available in the Google Chrome Web browser.

Users new to CEF development should start by reading the Tutorial Wiki page for an overview of CEF usage and then proceed to the GeneralUsage Wiki page for a more in-depth discussion or architectural and usage issues. Complete API documentation is available here. CEF support and related discussion is available on the CEF Forum.

Numerous individuals and organizations contribute time and resources to support CEF development, but more involvement from the community is always welcome. This includes support for both the core CEF project and external projects that integrate CEF with additional programming languages and frameworks (see the "External Projects" section below). If you are interested in donating time to help with CEF development please see the "Helping Out" section below. If you are interested in donating money to support general CEF development and infrastructure efforts please visit the CEF Donations page.
