Mixpanel

Mixpanel is a product analytics platform built for understanding user behavior and product engagement. It excels at funnel analysis, cohort segmentation, and retention metrics—essential for product teams optimizing conversion and growth. Unlike website analytics (Plausible, Fathom), Mixpanel captures every user action as an event, enabling retroactive analysis without predefined event setup.\n\nFor indie hackers and startup founders, Mixpanel's free tier is exceptional: up to 20M events/month, unlimited reports, custom dashboards, and cohorts. The Growth plan ($0.28 per 1K events after 1M free) scales affordably with usage. Eligible startups (founded <5 years, <$8M funding) get their first year free on the Startup Plan with access to all features including experiments and session replays—making this the best product analytics option for early-stage teams.
