MCEF is a mod and library for adding the Chromium web browser into Minecraft.

MCEF is based on java-cef (Java Chromium Embedded Framework), which is based on CEF (Chromium Embedded Framework), which is based on Chromium. It was originally created by montoyo. It was rewritten and currently maintained by the CinemaMod Group.

MCEF contains a downloader system for downloading the java-cef & CEF binaries required by the Chromium browser. This requires a connection to https://mcef-download.cinemamod.com.
