As per free tools, I recommend Posthog - Mixpanel. Both of these provide insights into your product usage and user behavior to help you make data-driven decisions and improve your products. Posthog is targeted to roles closer to web development or software related backround. Mixpanel is targeted to less technical backrounds Which tool has helped your business track user behavior and why?
