In contrast, Chromium is primarily distributed through third-party software repositories or via direct source code downloads from the Chromium Project's official site. Unlike Chrome, Chromium is not typically offered as a pre-installed browser on most operating systems, requiring users to manually download and install it.
Additionally, Chromium serves as the foundation for several other browsers. Browsers like Opera, Microsoft Edge, and Brave build upon Chromium's codebase, adding their own unique features and branding. This modular approach allows these browsers to leverage Chromium's robust performance and security while differentiating themselves through additional functionalities and design choices.
