Two million events a month, and three chances to overshoot before the account goes

65 sits in our Usable band and just above Mixpanel at 63, which is the comparison most readers are making. Generosity at 82 is doing the lifting: twice Mixpanel's allowance, twice PostHog's, on the same meter, plus 10,000 session replays and real slices of the wider platform rather than analytics alone.

Freedom at 35 is doing the pulling, and it is the lowest freedom score in this category apart from Google Analytics. Two facts account for it. The overage policy ends in a deleted account, which no other free plan here does. And no tier above Free publishes a dollar figure anywhere, so you cannot cost your own upgrade path without a sales conversation. A larger free tier that is harder to leave on your own terms is exactly the shape these two pillars are meant to capture. Full reasoning on all four sits below.

The 2 million event limit is the one on the page. The ones that catch people are underneath it (as of July 2026):

• Three overages, then a block. As a non-paying customer, exceeding the monthly limit three times blocks the account: no charts, no dashboards. Administrative functions like the User API keep running so compliance requests can still be served.
• Deletion at six months. If the overages continue without an upgrade, Amplitude deletes the account six months after the initial block. An abandoned free project that keeps ingesting is not harmless.
• 2,000 event types, 2,000 event properties, 1,000 user properties per project. This applies on every plan, not just Free, and past it Amplitude stops indexing new values. It happens quietly, which makes a sprawling taxonomy genuinely risky.
• 30 events per second per user or device, above which requests are throttled. Load tests and bulk imports meet this first.
• Hidden, backfilled and inactive events all count towards your 2 million. Identify and Group Identify calls, blocked IDs, deleted events and computed events do not.
• Free withholds custom events and formulas, behavioral cohorts, alerts and heatmaps, and the 2-year data retention window is a Plus feature.

Three things we could not verify first-party and therefore do not state: what the free plan's own retention window is, what happens to historical data if you downgrade, and whether any plan caps seats. Treat all three as open questions before you commit a team to this.

Here is the honest situation: effectively nothing above Free carries a number. Plus says it starts at $0 and bills pay-as-you-go, but it requires a credit card at signup, scales to 70 million events and includes 2-year data retention. Growth and Enterprise both say "Custom" against "Event based pricing", with 20,000 and 50,000 monthly session replays respectively and unlimited projects plus role-based access control at the top (as of July 2026). The bill estimator runs in the browser, so there is no list rate on the page for anyone to read, including us.

That is a real difference from the tool most readers are comparing this against. Mixpanel's free plan sits under a published rate of $0.28 per 1,000 events and a stated 20 million event ceiling, which means you can model the cost of growth in a spreadsheet. With Amplitude you model it in a meeting.

What most people upgrade for is not extra volume. It is behavioral cohorts and alerts, both of which sit above Free, and then the 2-year retention window on Plus. If your analysis is going to run across quarters rather than weeks, that retention line is the one that decides it.

A note on the numbers you may find elsewhere. An October 2023 Amplitude press release quoted a Plus tier starting at $49 a month. The current pricing page says Plus starts at $0, so that figure is superseded and we are not carrying it forward.

Yes, within limits, and the limits are the largest on offer here. Two million events a month with no card is a serious amount of free product analytics, and unlike most free tiers in this category it gives you slices of the whole platform rather than the analytics module alone.

The condition is unusual enough to state as an instruction rather than a caveat: somebody has to own the account. This is the only free plan on this site whose published policy ends in deletion, so a project that gets instrumented, forgotten, and then keeps firing events past the cap can eventually be removed. Set the tracking down properly when you stop using it.

Who lives here comfortably: a growth or product team under 2 million events a month with a disciplined event taxonomy, especially one that would otherwise pay separately for analytics, experimentation and in-product guides. Who should not: any team that needs to plan a budget, because the price of the next tier is not published; anyone with a sprawling taxonomy heading for 2,000 event types; and anyone who wants a self-hosted exit, because there is not one.

If published pricing is what you want, PostHog's free plan prints every per-unit rate and simply stops ingesting at the cap. Free Amplitude alternatives ranks the options, and the best free analytics tools covers the category.
