No. 22 of 30 ยท Product and event analytics
Heap
Captures everything automatically, so you can answer questions you had not thought to instrument.
Its autocapture model means you can define an event today and get months of historic data for it retroactively.
The verdict
Heap's founding idea is still its best one: capture every click, form submission and pageview automatically, then let people define events afterwards and apply them backwards through the history. Every other tool in this category makes you decide in advance what matters and punishes you in six months when it turns out you were wrong. Heap does not, and for teams who have lived through that particular disappointment, it is the whole reason to buy.
In practice that means a product manager can ask a question on Tuesday and have an answer covering the last six months, without an engineering ticket. That is a genuine change in how quickly a team can learn.
What you actually get
The trade is noise. Autocapture produces an enormous, undifferentiated event stream, and the discipline that Mixpanel forces at instrumentation time has to happen at analysis time instead, in the form of careful event definitions and a governance habit. Teams who lack that habit end up with a different mess rather than no mess.
The commercial position has also weakened. Heap was acquired by Contentsquare in 2023 and now sits inside a larger experience-analytics portfolio alongside Hotjar, which raises the ordinary questions about roadmap independence and cross-selling that any acquisition does. Paid pricing is quoted rather than published, which on a list where most vendors put their numbers on a page is a mark against it: you cannot compare what you cannot see, and the value score of 5 reflects that opacity as much as the price.
Best for
Product teams who want to ask retrospective questions without having predicted them, and who have the governance habits to keep an autocaptured event stream usable.
Getting it running
A single snippet and autocapture does the rest, which is genuinely the easiest start in this category. The work moves to defining and governing events afterwards.
What to watch out for
Paid pricing is not published, so budgeting means a sales conversation. Autocapture generates noise that needs active governance. Cookies and a consent obligation in the EU and UK. Now part of Contentsquare, with the roadmap questions that follow an acquisition.
Pricing and practicalities
A free tier with a session limit, then quoted plans. Owned by Contentsquare since 2023, which also owns Hotjar. Prices read 2026-09-11, to the extent they are published at all.
Who should go elsewhere
Anyone who needs to compare costs before talking to a salesperson, where PostHog and Mixpanel publish their numbers. Also wrong for websites rather than products, where Plausible Analytics does more of what you need with less of what you do not.
How it compares
Against Mixpanel the question is whether you would rather do the thinking up front or afterwards. Against PostHog, which also autocaptures, Heap's advantage is retroactive definition and PostHog's is published pricing and a much larger free tier.
Head to head:
The ten measures
Each measure is scored 0 to 10 and weighted. The overall figure is the weighted mean, and it is relative to the other 29 tools on this list rather than absolute. How this works.
What this rests on
Heap's own product and pricing pages, read 2026-09-11; Contentsquare's published announcement of the acquisition; Heap's documentation on autocapture and retroactive event definition.
Desk research against published material. Because paid pricing is not published, the value score rests on the free tier and the opacity itself rather than on a comparable price, and should be read as provisional.
This is a desk review. I have not been given access by the vendor, I have no commercial relationship with them, and everything above is my opinion rather than a statement of fact. If something here is wrong, tell me and I will correct it.
