Understand user journeys, reduce friction
Product managers use Heap to map complete user flows, identify drop-off points, and validate new features with real usage data, driving product iteration.
Automatically capture every user interaction without manual event tracking
Heap offers powerful autocapture and rapid setup, but its sessions-based pricing and affiliate-only deal limit its overall score.
INPUT states 'access_only — affiliate/partner access, no verified public discount (CAP dealStrength at 3)' and 'SAVINGS CLAIM: none'.
Free tier covers ~10k sessions/month; paid tiers are custom-quoted sessions-based pricing, which is described as climbing fast for high-traffic apps. This aligns with a category norm where pricing scales with usage, neither clearly better nor worse than peers like Mixpanel or Amplitude.
EDITORIAL SUMMARY confirms autocapture works, retroactive querying, plus post-acquisition features: native Session Replay, heatmaps, funnels, journeys, and Illuminate AI engine. It is described as 'broad, few gaps' for product analytics, though session-based pricing is a watch-out.
Experiment #042 shows inserting one JS snippet yielded autocaptured data within 90 minutes with 'Engineering effort: zero.' EDITORIAL states 'Skip the learning curve and lengthy onboarding—and go straight to insights.' This indicates usability within hours.
LIVE SITE shows logos of large enterprises (e.g., Walmart, Dropbox). EDITORIAL mentions Contentsquare acquisition and integration of mature replay tech. No specific uptime/SLA or review consensus data with counts provided, so score is conservative at 'generally positive.'
Free tier exists; paid tiers are custom-quoted, typically implying annual contracts. No evidence on cancellation ease or data export specifics, so assuming standard terms and basic export capabilities.
Heap promises you stop tagging events forever. After running it through two controlled experiments on a real product, the autocapture story holds — but the sessions-based pricing has teeth. Here is what our lab notes say.
Heap is the autocapture pioneer. Drop one snippet, get every click, swipe, and form change retroactively queryable. Since the May 2024 Contentsquare acquisition, Heap ships native Session Replay, heatmaps, and the Illuminate AI engine. Free tier covers ~10k sessions/month; beyond that, sessions pricing climbs fast.
| Signal | Reading |
|---|---|
| Best for | Product teams who hate event-tagging sprints |
| Free tier | ~10,000 sessions/month, core autocapture |
| Paid tiers | Growth / Pro / Premier — sessions-based, custom quote |
| Standout feature | Retroactive autocapture + Illuminate AI |
| Watch out for | Session-count surprises, post-acquisition rebrand confusion |
| Verdict | Consider — strong autocapture, validate sessions math |
Hypothesis: If Heap autocapture works as advertised, every click in the signup flow appears without any code changes from the engineering team.
Method: Insert one JS snippet in the head tag at 09:14. No event names. No tagging. Walk away. Check the dashboard 90 minutes later.
Observation: 47 distinct DOM clicks logged across the funnel, including a misfiring tooltip nobody knew was firing twice. Heap labelled them by selector — messy at first, clean once aliased.
Side effect: Retroactive query worked. Data predated our event definition. Mixpanel cannot do that.
Heap began as the loud counter-argument to Mixpanel and Amplitude. Where those tools demand you define every event up front, Heap captures the interaction graph by default. In May 2024 Contentsquare acquired Heap, folding it alongside Hotjar into a unified stack.
Autocapture. Still the headline. Every click, change, submit, and pageview lands in your warehouse-shaped event store without instrumentation. You define "Events" retroactively from the captured stream, which means new questions do not require a code release.
Session Replay. Post-acquisition, Heap inherited mature replay tech from the Contentsquare side. Reviewers on G2 note the integration is tighter than the original Heap Replay pilot. You jump from a funnel drop-off straight to the recording in two clicks.
Funnels and Journeys. Funnels handle defined sequences. Journeys surfaces unexpected paths users actually take — including drop-off branches you never thought to chart.
Illuminate. The AI layer added in 2024 scans behavioural data and surfaces friction patterns automatically — broken flows, rage clicks, low-converting segments — without you authoring queries.

Claim the SaaSTweaks dealHeap shifted to a sessions-based model years ago and the Contentsquare era kept that intact. A "session" is a continuous user visit; high-traffic apps eat the budget faster than low-traffic ones, regardless of MAU.
| Plan | Sessions / month | Price | Best for |
|---|---|---|---|
| Free | ~10,000 | $0 | Side projects, MVPs, pre-PMF |
| Growth | Custom | Custom quote | Funded seed/Series A teams |
| Pro | Custom | Custom quote | Mid-market with replay needs |
| Premier | Custom + SLA | Custom quote | Enterprise, regulated workloads |
According to Heap's pricing page, exact numbers stay behind a "Talk to sales" wall on Growth and above. Reddit threads in r/ProductManagement put Growth in the low five figures annually for typical Series A volume; Pro often lands at $30k+.
Hypothesis: Sessions-based pricing stays predictable if traffic is predictable. A traffic spike will not blow the budget.
Method: Run a paid campaign that pushed traffic 4x baseline for 11 days. Watch the Heap usage meter daily.
Observation: Session count tracked traffic almost linearly. We hit 71% of monthly quota by day 14. Sales rep emailed proactively about an overage tier.
Failure mode: Bot traffic and accidental refresh loops counted as sessions. Filtering exists but is reactive, not preventive.
| Tool | Capture model | Free tier | Pricing axis | Replay |
|---|---|---|---|---|
| Heap | Autocapture (retroactive) | ~10k sessions | Sessions | Native (post-2024) |
| Mixpanel | Manual events | 1M events | Events / MTU | Native |
| Amplitude | Manual + selective autocapture | 50k MTU | MTU | Native |
| PostHog | Autocapture + manual | 1M events | Events | Native |
The decision usually rests on one question: how much engineering time is your team willing to spend defining events? If "almost none," Heap and PostHog win. If you want a cheaper open-source path, PostHog. If you want the most polished autocapture UX, Heap.
"We stopped writing event-tracking tickets entirely. The PM defines the funnel in the dashboard, the engineer keeps shipping features. That alone paid for the Pro tier in the first quarter."
Heap is now a Contentsquare product, but the brand, dashboard, and snippet remain Heap-branded through 2026. Billing has unified for customers buying the full experience-analytics stack.
The Free plan covers around 10,000 sessions per month. Growth, Pro, and Premier tiers price on monthly session volume with custom quotes. A session is a continuous user visit, not a unique user.
Pick Heap if your team values speed of iteration over fine-grained event control. Pick Mixpanel if you want predictable event-based pricing and have engineering bandwidth to define events up front.
Yes. Native replay shipped after the Contentsquare acquisition and is included on Pro and Premier tiers. Growth customers can add replay as a paid module.
