Which version of Google Analytics is free?

Google Analytics offers a free version called "Google Analytics Standard." The free version is available to all users, and it provides a robust set of features for tracking website and app analytics. Many individuals, small businesses, and even larger enterprises use Google Analytics Standard for basic to advanced web analytics needs.

However, it's important to note that Google Analytics also offers a premium version called "Google Analytics 360," which is a paid, enterprise-level solution with additional features and support. Google Analytics 360 is designed for larger organizations or those with more complex analytics requirements.

Google's offerings and plans may evolve over time, so I recommend checking the official Google Analytics website or contacting Google directly for the most up-to-date information on their products and pricing.
