Chromium is an open-source web browser project initiated by Google. Released under the BSD license, Chromium's source code is freely available for developers to modify, enhance, and distribute. This openness fosters a collaborative environment where contributions from the global developer community continuously improve the browser's functionality and security.
Being the upstream project for Google Chrome, Chromium serves as the foundational codebase. Developers can use Chromium to build their own browsers, adding unique features or customizing the user experience to suit specific needs. This flexibility makes Chromium a popular choice for various browser derivatives like Opera, Microsoft Edge, and Brave.
