In contrast, Google Chrome is a proprietary browser developed by Google that builds upon Chromium's codebase. While Chrome incorporates all the core functionalities of Chromium, Google adds proprietary features, branding elements, and services that enhance the user experience. These additions are not available in the open-source Chromium project and are part of what differentiates Chrome from its open-source sibling.
Google Chrome includes components such as automatic updates, integrated Google services, and support for proprietary media codecs, all of which contribute to a more polished and user-friendly browsing experience. However, these proprietary elements mean that Chrome is not entirely open-source, limiting the ability for developers to modify certain aspects of the browser.
