Chromium is the open source web browser project from which
Google Chrome draws its source code. The project's hourly Chromium
snapshots appear essentially similar to the latest builds of Google
Chrome aside from the omission of certain Google additions, most
noticeable among them: Google's brand, auto-update mechanism,
click-through licensing terms, usage-tracking, and bundling of Adobe
Flash Player.
The Chromium Project takes its name from the element
chromium (Cr), the metal from which chrome is made. Google's intention,
as expressed in the developer documentation, was that Chromium would be
the name of open source project and that the final product name would be
Chrome. However other developers have taken the Chromium code and
released versions under the Chromium name
