Our verdict
PostHog is the best all-in-one choice for startups — you get analytics, session replay, feature flags, and A/B testing in a single tool with a generous free tier. Amplitude excels at advanced behavioral analytics and cohort analysis for product teams at scale, and now bundles session replay on every plan. Mixpanel has closed its old gaps — session replay is included and feature flags exist as an add-on — but its free tier was cut to 1M events, erasing its former volume advantage. For most early-stage startups, PostHog gives you the most value per dollar.
