[4] CEF 1 is a single-process implementation based on the Chromium WebKit API.

[5] CEF 3 is a multi-process implementation based on the Chromium Content API and has performance similar to Google Chrome.

As of July of 2022, it no longer supports PPAPI plugins due to removal of PPAPI, legacy Chrome Apps, and Native Client (NaCl) support from the upstream Chromium project.

CEF comes with a sample application called CefClient that is written in C++ using WinAPI, Cocoa, or GTK (depending on the platform) and contains demos of various features.
