What is the best free analytics tool?

Google Analytics 4 is free and the most widely deployed web analytics platform. For product analytics, Mixpanel's free plan covers 20 million monthly events.

Do I need Mixpanel if I have Google Analytics?

GA4 is great for marketing analytics (traffic, acquisition, conversions). Mixpanel is better for product analytics (feature adoption, retention, funnel analysis). Many teams use both.

What is the best analytics tool for startups?

Mixpanel's free plan is excellent for early-stage product analytics. Hotjar's free plan helps identify UX issues. Both are zero-cost to start and scale with your growth.
