Amplitude vs Mixpanel: pricing, features and which product analytics tool fits your team

The core analytics are close to equivalent in 2026. Both capture user actions as events, resolve identity across sessions, and build funnels, retention curves, cohorts and segmentation from that stream. The differences that matter are packaging and depth, not whether a given report exists.

Amplitude packages more into the platform. Session replay, experimentation, guides and surveys and its AI layer are part of every tier rather than separate purchases, and its account-level reporting suits B2B products where the customer is a company, not a person. Mixpanel is narrower on purpose and prices accordingly, treating experimentation and warehouse connectors as add-ons on Growth. The practical effect is that Amplitude tends to be the platform decision and Mixpanel tends to be the analytics decision.

It depends entirely on your event volume and what you need bundled, and the free tiers point the other way from what most people assume. Amplitude's free plan allows 2 million events a month, double Mixpanel's 1 million, so a small team often stays free longer on Amplitude.

Above the free tier the comparison inverts in usefulness. Mixpanel publishes $0.28 per 1,000 events past the first million, so you can multiply your expected volume and get a real number before talking to anyone. Amplitude publishes allowances rather than a rate above Plus, so budgeting past that point means a sales conversation. Mixpanel is not automatically cheaper, but it is far more predictable. If you need experimentation and warehouse connectors, add Mixpanel's add-on costs back in, because those are included in Amplitude's tiers.

Yes, Mixpanel has a permanent free plan capped at 1 million monthly events, with up to 5 saved reports and 10,000 monthly session replays. It is a real product rather than a trial, and a small team tracking a focused set of events can run on it indefinitely.

The cap that bites first is usually the 5 saved reports, not the event ceiling. Once several people are building analyses, you run out of report slots long before you run out of events, and that is the point most teams move to Growth. Qualifying early-stage companies can also apply to Mixpanel's Startup Plan, which makes the first year free at a higher tier. Amplitude's free plan is more generous on volume at 2 million events a month and does not cap report count the same way.

PostHog is the third name that belongs on most shortlists, and it wins on a different axis. It bills usage-based per product with no platform fee, includes the first 1 million analytics events a month free, and puts analytics, session replay and feature flags on one bill with the source code available. For an engineering-led team that is often decisive.

Pick Amplitude when the buyer is a product organization that wants a governed platform and account-level analysis. Pick Mixpanel when a product manager needs to self-serve behavioral analysis at a predictable unit cost. Pick PostHog when engineers own the stack and want to avoid per-seat and platform fees. All three are credible; the wrong move is buying the biggest one before you have the volume or the owner to use it.

Technically yes, and almost always you should not. Both read the same event stream, so running them side by side means maintaining two tracking plans, reconciling two sets of numbers, and paying twice for answers to the same question. Teams that do this usually got there through a migration that stalled halfway.

The pairing that does earn its place is a behavioral tool plus something that answers a different question. One platform tells you what happened: which step lost users, which cohort decayed, which feature never got adopted. A second layer tells you why, by reading the tickets, reviews and survey replies those same users wrote. That is a genuine division of labor rather than the same report bought twice, and it is how UserInsight is meant to sit next to whichever of these two you choose.

Not for product questions. GA4 is built around acquisition: where traffic came from, which campaigns converted, how landing pages performed. Amplitude and Mixpanel are built around the logged-in experience, modeling individual users over time so retention, cohort and feature-adoption questions have real answers.

The difference is identity and event-level detail. Product analytics resolves a person across sessions and devices into a stable user, which is what makes a retention curve trustworthy, and keeps events queryable rather than pre-aggregating them into fixed reports. Most SaaS teams end up running both: GA4 for how people found them, and Amplitude, Mixpanel or PostHog for everything that happens after signup. Treating GA4 as sufficient for product analytics is the most common and most expensive shortcut in this category.
