Chromium is an open source web browser which employs the Blink engine. The heavily advertised Google Chrome is essentially this Chromium browser, which has been simply re-branded and slightly modified. The rendering engine is the same, meaning it offers the same speed and stability (or lack there of, depending on your opinion) of Chrome. Chromium is a fast, stable browser with a wide variety of available plug-ins. The Chromium code base is used by numerous other browsers as well, including Brave, Microsoft Edge, Opera, and Vivaldi.
