Chromium and Chrome are closely related yet distinct web browsers, with Chromium serving as the open-source foundation for Chrome. Chrome, developed by Google, dominates the browser market with its proprietary features like automatic updates, built-in media codecs, and Adobe Flash support, which are absent in Chromium. While Chromium offers a more flexible and privacy-focused experience, requiring users to manually install updates and extensions, it lacks the convenience and stability of Chrome's features. Chrome's extensive user base and compatibility across devices make it a preferred choice for general users, while advanced users and those valuing open-source software may prefer Chromium. Both browsers are pivotal in cross-browser testing, with platforms like LambdaTest enabling comprehensive testing across various versions and operating systems to ensure optimal website performance.
