The Chromium Embedded Framework (CEF) is a library for embedding Chromium-based web browsers in native applications. It provides a stable, simplified API that insulates developers from Chromium's complexity while enabling full-featured web content rendering, JavaScript integration, and bidirectional communication between native code and web pages. The architecture follows a multi-process model (browser, renderer, GPU) with clear separation of concerns: the browser process manages UI, lifecycle, and resources; the renderer process handles web content rendering via Blink/V8; and the client application customizes behavior through delegate interfaces (e.g., CefLifeSpanHandler, CefRenderHandler). CEF supports cross-platform deployment (Windows, macOS, Linux) with multiple UI toolkit options (native views, Chromium's Views framework, or off-screen rendering). Key entry points include CefInitialize/ CefRunMessageLoop for application setup and the CefClient interface for handling events. The framework relies on Chromium as its core dependency, supplemented by platform-specific libraries and build tools like GN/Ninja. CEF is widely used in production for applications requiring embedded web views, such as IDEs, desktop wrappers for web apps, and automated testing tools.
