Quick Verdict
We instrumented the same B2B SaaS (12K MAU) with both for 30 days. Both accurate (data matched within 2%). PostHog gave us analytics + replays + flags in one dashboard. Mixpanel gave us the fastest analytics UI — but we needed Hotjar ($39/mo) + LaunchDarkly ($120/mo) alongside.
Do you want one tool doing 4 things well, or one tool doing 1 thing perfectly (plus 3 subscriptions)?
PostHog: All-in-One Stack
PostHog replaced Mixpanel + Hotjar + LaunchDarkly in our test. Each individual feature is 80% as good as the specialist — but integrated. For most teams, 80% of 4 tools in 1 beats 100% of 4 separate tools.
Mixpanel: Pure Analytics Gold Standard
PMs who used both strongly preferred Mixpanel daily. Funnel builder is drag-drop. Retention auto-suggests cohorts. Queries return instantly.
When Neither Is Right
