Mixpanel vs Google Analytics: cost, GA4 sampling limits, and how Mixpanel vs GA4 compares

For understanding behaviour inside a product, yes, clearly. For understanding how people found your website, no, and it is not close. They are built for different halves of the funnel, and which one is better is decided entirely by which half your unanswered question sits in.

Google Analytics carries fifteen years of accumulated integration with the advertising and search ecosystem. Campaign attribution, channel grouping, Search Console and Google Ads connections, and a reporting vocabulary every marketer already speaks fluently. Mixpanel competes with none of that, and swapping GA4 out for marketing measurement is a downgrade no one should attempt as a matter of principle.

Mixpanel wins as soon as the subject is a logged-in user. Unsampled queries at any volume, user properties you define to match your own business, funnels and retention that survive being segmented, and session replay to watch the drop-off you just measured. It also has a property GA4 lacks entirely: a price you can calculate in advance. The honest framing is that Mixpanel is better at product analytics, GA4 is better at marketing analytics, and the mistake to avoid is stretching either one across both jobs.

Yes, there is a real free plan with no credit card required, and it is more useful than most free tiers in this category. It covers 1 million events a month and 10,000 session replays. What ends it for most teams is not the event volume, and this is the detail almost nobody reports.

The free plan allows 5 saved reports per seat. That is the wall you actually hit. A single analyst building out a proper activation funnel, a retention curve, a feature adoption report, a signup source breakdown and one weekly dashboard has spent the entire allowance. Everything after that gets rebuilt from scratch each time somebody wants to look at it, which is exactly the friction that stops an analytics practice from forming. Teams routinely conclude Mixpanel does not work for them when what actually happened is they hit a reporting cap, not a data cap.

Above free, Growth starts at $0 and bills by event volume with published rates and a public calculator, running up to 20 million events a month and 500,000 session replays. Enterprise is quoted and scales to a trillion events a month. Worth checking before you pay anything: companies founded less than five years ago that have raised up to $8 million can get their first year free on the Startup Plan, which removes the cost question entirely for a large share of the teams reading this.

Yes. On a standard GA4 property, explorations begin sampling once a query covers more than 10 million events, and Google publishes that threshold in its own standard versus 360 comparison. Analytics 360 raises the same limit to 1 billion events per query.

Sampling matters more than it sounds because it does not announce itself in a way anyone notices. The exploration renders normally, the funnel has bars, the retention curve curves. What changed is that the numbers underneath were estimated from a subset. For a report on channel performance, an estimate is usually fine. For deciding whether an onboarding change moved activation for one plan tier, an estimate drawn from a sample of a segment that was already small is a poor foundation for a roadmap.

The threshold arrives sooner than the number suggests. A moderately instrumented SaaS product crosses 10 million events a month without being large, and any exploration spanning a few months of that data crosses it instantly. Mixpanel does not sample at any volume, which is an architectural property rather than a marketing claim. If unsampled numbers are the reason you are on this page, that single row is your answer and the rest of the comparison is detail.

Use both, and decide deliberately which question goes to which tool. That is not a dodge. It is what most Mixpanel customers actually do, because dropping GA4 costs them marketing measurement they still need, and dropping Mixpanel costs them product measurement GA4 cannot supply.

The split that works in practice: GA4 owns everything before signup. Acquisition channels, campaign performance, landing page conversion, Search Console and Ads integration. Mixpanel owns everything after signup. Activation, feature adoption, funnels inside the product, retention by cohort and session replay. The handover point is the account creation event, and instrumenting that one event in both tools is what later lets you connect an acquisition channel to a retained customer.

If you genuinely must run only one, decide by where your unanswered questions live rather than by feature count. A company selling a media property, a content site or an ecommerce catalogue should stay on GA4 and spend the money elsewhere. A B2B SaaS company whose growth problem is activation or churn should run Mixpanel and accept thinner attribution. The option to avoid is stretching GA4 across both jobs and quietly making product decisions on sampled data, which is the position most people are already in when they start searching for this comparison.

This three way version is a common search, and the useful way to resolve it is that GA4 is in a different category from the other two. Mixpanel and Amplitude are direct competitors doing the same job. GA4 is a marketing tool that people try to stretch into that job.

Between Mixpanel and Amplitude the differences are narrower than either vendor's marketing implies, and they mostly come down to billing and packaging. Both meter events rather than tracked users. Amplitude's free tier is considerably larger at 2 million events a month with unlimited seats, but SSO and project permissions sit on Growth and above, which are quoted. Mixpanel's free tier is 1 million events but caps saved reports at 5 per seat. Amplitude tends to win on breadth of built-in analysis; Mixpanel tends to win on speed of everyday querying and on how easily you can model the bill.

Against either of them, GA4's position is the same: free, excellent for acquisition, and structurally limited for product work by sampling, a 14 month retention cap and 50 custom dimensions. The practical shortlist for most teams is GA4 plus one of the other two, not all three, and the two paid options are close enough that the deciding factor is usually which billing model fits your instrumentation rather than which feature list is longer.

Yes, and it is the normal arrangement rather than an unusual one. The two overlap far less than the comparison framing suggests, so running both duplicates much less work than running two product analytics tools would.

The setup is straightforward. Both are JavaScript snippets and both deploy cleanly through a tag manager. GA4 stays on the marketing site and the signup flow, Mixpanel goes into the authenticated product. The detail that makes it worthwhile is the handover: fire the signup event into both tools with a shared identifier, so a channel recorded in GA4 can later be joined to a retention cohort in Mixpanel. Skip that and you own two accurate systems that can never answer a question spanning both.

Budget for the maintenance rather than the money. Two instrumentation paths drift apart unless one person owns keeping event definitions aligned, and the two tools will report different figures for anything that looks superficially similar, because a GA4 session and a Mixpanel user are not the same object. Decide in advance which tool is authoritative for which metric and write it down, or you will spend the next year relitigating whose number is correct.

There is no public price list, which is worth stating clearly because a surprising number of comparison pages assert that Google Analytics has no paid tier at all. It does. Analytics 360 is the enterprise version, sold on annual commitments through Google's sales team or a reseller.

Reported entry points sit around $50,000 a year and scale with event volume, with mid-market deployments commonly reported between $100,000 and $175,000. Treat every one of those figures, including these, as reported rather than official. One specific correction is worth making because the number is repeated everywhere: the widely cited $150,000 price tag dates from the Universal Analytics era and is not a GA4 360 rate card.

What 360 actually buys you is the removal of the limits that make standard GA4 unsuitable for product analytics: exploration sampling moves from 10 million to 1 billion events per query, retention extends to as much as 50 months, BigQuery export goes from 1 million events a day to effectively uncapped, and custom dimensions rise from 50 to 125. If you are considering 360 specifically to fix sampling and retention, price a product analytics tool alongside it, because Mixpanel's published rates will very often come in below a 360 contract while solving the product question more directly.
