Best forEngineering-led teams that want several tools in one bill.Product managers who want self-serve behavior reports.
A custom build beats it whenRarely; a custom warehouse model makes sense only once you have analysts and data in many places.Rarely; same answer, a warehouse plus BI once analytics questions span billing, CRM and product data.

The verdict

Both have generous free plans of about 1M events a month, so cost rarely decides it early.

PostHog bundles analytics, session replay, feature flags, experiments and surveys, with per-product billing limits; it suits an engineering-led team that wants one tool. Mixpanel is a focused analytics tool with polished reports for funnels, flows and retention, unlimited seats on free, and a warehouse connector; it suits product and growth people who want to answer questions themselves. Watch the free-plan edges: PostHog drops events past the allowance, and Mixpanel blocks report access past 1M events until you upgrade or the cycle resets.
