Mixpanel

Mixpanel is an event-based product analytics platform: it records what users do inside a product as discrete events, then answers questions about funnels, retention, cohorts, and user flows on top of that event stream. The distinction that matters is event analytics versus page analytics. A tool like Google Analytics is built around pageviews and sessions, which answers marketing questions well and product questions badly. Mixpanel is built around a user doing a thing - signed_up, created_project, invited_teammate - so a product team can ask where in a five-step onboarding people drop out, whether the users who invite a teammate in week one retain better, and which cohort a feature actually moved. Pricing as of 2026: the Free plan is free forever with up to 1 million events per month, 10,000 session replays per month, and core funnel and retention analysis, with no credit card required. The Growth plan starts at $0 and scales with volume, covering up to 20 million events and 500,000 session replays per month, and adds behavioural cohorts, unlimited saved metrics, and multi-touch attribution. Enterprise is quote-based, scales to 1 trillion events per month, and adds anomaly detection, feature flags, experimentation, and security controls. Mixpanel reports more than 29,000 companies on the platform. The 1 million free events per month is the number that decides most early-stage evaluations. It is genuinely enough to run a pre-product-market-fit startup on indefinitely, which is why Mixpanel is common in seed-stage stacks. Who it is for: product managers and growth teams who need to answer behavioural questions rather than traffic questions, at companies past the point where reading the database directly is fast enough. The main implementation caveat is that event analytics is only as good as the tracking plan. Mixpanel gives you nothing useful until someone decides what the events are and instruments them consistently, and a sloppy taxonomy is expensive to fix later. Budget the design work, not just the tool. How it compares: Amplitude is the closest peer and the usual head-to-head, generally stronger on advanced behavioural analysis and enterprise governance. PostHog bundles analytics with session replay, feature flags, and experimentation in one open-source platform and is the more popular choice among engineering-led teams. Heap auto-captures every interaction, which removes the tracking-plan burden but produces noisier data. Google Analytics 4 is free and unavoidable for marketing attribution but is not a product analytics tool. Pick Mixpanel when the questions are about behaviour inside the product and someone owns the tracking plan.
