Things people build with this

USE CASE 1

Add an in-app web browser to a native desktop application so users can view web content without leaving the app.

USE CASE 2

Render web-based UIs (dashboards, storefronts, help panels) inside a game or creative tool using the same engine as Google Chrome.

USE CASE 3

Automate or test web browser behavior programmatically using CEF's C++ API or one of the community language bindings.

USE CASE 4

Use off-screen rendering to capture web content as an image or texture for display in a custom 3D graphics pipeline.

Binary distributions are available for all platforms so no Chromium build is needed, but integrating into an existing app with its own event loop requires careful message loop bridging.

Use, modify, and distribute freely for any purpose including commercial use, as long as you include the BSD license notice.

In plain English

The Chromium Embedded Framework (CEF) is an open-source project that lets developers embed a full, standards-compliant web browser inside another application. The browser engine it uses is the same one that powers Google Chrome, so any application built with CEF can render modern websites, run JavaScript, play video, and handle HTML5 features just as Chrome does. CEF is useful in several situations. A native desktop application might want to display a web-based interface without redirecting users to an external browser. A game or creative tool might render an in-app store or help panel built with web technologies. Testing tools use it to automate web browsers programmatically. CEF also supports off-screen rendering, where web content is drawn to an image or texture rather than a visible window, which is useful for applications with custom graphics pipelines. The framework is written in C and C++, providing an API that shields developers from the internal complexity of Chromium and the Blink rendering engine. This means application code does not need to track changes inside Chromium itself, CEF maintains stable release branches that correspond to specific Chromium versions. Binary distributions, meaning pre-compiled files ready for use, are available for download and do not require building Chromium from source. Beyond C and C++, a number of externally maintained projects make CEF accessible from other languages, including .NET, Java, Go, Python, and Delphi. These are community-maintained and not part of CEF itself. CEF was founded in 2008 and has over 100 million installed instances worldwide, used by companies across many industries. The project is BSD-licensed. Documentation, tutorials, and an API reference are available from the project website.

Copy-paste prompts

Prompt 1
Show me a minimal C++ CEF application that opens a window, loads a URL, and displays the page using the pre-built binary distribution.
Prompt 2
How do I use CEF off-screen rendering in C++ to capture a web page as a bitmap image without showing a visible window?
Prompt 3
What is the process for adding CEF to an existing C++ desktop app that already has its own window and message loop, without conflicts?
Prompt 4
How do I use the .NET or Java language bindings for CEF to embed a web browser in a non-C++ application?
Prompt 5
How do I set up CEF to inject JavaScript into a loaded web page and receive callback results back in my C++ application?
