Chromium Embedded Framework (CEF) is an extension of the Chromium browser rendering engine, an open-source project which is a component of Google Chrome, and since 2020, Microsoft Edge, aswell as many other Wikipedia icon Chromium-based browsers.

In relation to Valve

The Steam client on Windows, Linux, and macOS previously a customized version of CEF to render web content like the Store and Community. As of June 15, 2023, the entire UI was remade with web technologies and is now rendered using CEF, replacing the old VGUI interface. VGUI was not completely removed, and was kept just in case CEF stops working correctly, telling users to restart Steam, or to warn users that Windows compatibility mode is enabled.

The Source code for Valve's modified version of the Chromium Embedded Framework (and Chromium) can be downloaded as a ZIP archive (783 MB, 24th April 2012). A patch for revision 465 of the CEF codebase is available on pastebin (280 KB) that will apply Valve's changes.
