Which do you use?
Who Should Choose What?
→ Choose PostHog if:
You want all product tools (analytics, flags, recordings, experiments, surveys) in one platform. You want open-source and self-hosting options. You're an engineering-led team that values consolidation over specialization.
→ Choose Mixpanel if:
You want the deepest funnel analysis and cohort tools available. You're a PM or data analyst who needs polished reporting. You already have separate tools for feature flags and session replay. You need the most generous free event quota.
→ Consider neither if:
You only need simple website traffic analytics — Google Analytics 4 or Plausible will do the job. For pure session recording without analytics, Hotjar is simpler and cheaper.

Frequently Asked Questions
Editor's Take
Here's the real calculation: PostHog free + no LaunchDarkly ($400/mo) + no Hotjar ($80/mo) = saving $480/mo even before you factor in analytics. Mixpanel's 20M free events are tempting, but you'll spend that savings on Hotjar and LaunchDarkly anyway. Unless your PM team specifically needs Mixpanel's funnel builder, PostHog is the smarter financial decision.
