Amplitude vs Heap: Which Is Better for Your Business?

Amplitude and Heap help product and growth teams explain what customers do, where they become stuck and which experiences lead to activation or revenue. Both support behavioral analytics, funnels, segmentation and ways to investigate journeys. Their differences are less about whether a chart exists and more about how data gets collected, what other products share that data, how the contracts meter usage and which team can work independently after launch.

Amplitude has evolved beyond an event-chart tool. Its current platform connects product and web analytics with Session Replay, feature flags, A/B testing, guides, surveys, AI features and data activation. Heap, now part of Contentsquare, remains notably focused on broad interaction autocapture, retroactive event definition and exploring behavior that was not anticipated when a tracking plan was written. Heap also offers funnels, journeys, retention, account analytics and AI functions depending on subscription.

Pricing makes this an especially important comparison to research rather than repeat from older articles. Amplitude Free includes two million monthly events. Its Plus plan starts at $0 because the first two million events remain included, then scales with event volume; Growth and Enterprise require quotes. Heap Free permits up to 10,000 monthly sessions, Growth requires a usage-informed estimate, and Pro/Premier are custom-priced by sessions. A session is not the same unit as an event, and neither a free-tier threshold nor a marketing discount demonstrates which product will cost less for your traffic.

This article compares the publicly documented products as of October 24, 2026, using U.S.-relevant plan information and published Toollers profiles. It explicitly distinguishes legacy Heap packaging from Contentsquare's newer Experience Analytics and Product Analytics offerings. The judgments are research-based; Toollers has not documented an independent controlled implementation, speed benchmark or hands-on comparison and does not claim otherwise.

Quick verdict

Amplitude vs Heap at a glance

What each product actually does

Amplitude is a behavioral measurement and product-action platform. Its SDKs send interactions, user properties and other context into a shared analysis layer. Teams can build charts for funnels, retention and journeys, identify cohorts, investigate selected sessions, target guides or surveys, run experiments and connect insights to growth workflows. Those capabilities have independent plan limits; broad availability on a pricing card is not the same as unlimited usage.

Heap is product analytics built around capturing many interactions automatically and giving analysts room to ask questions later. It can be useful where a team releases frequently and has not predicted every click, form step or navigation pattern worth analyzing. Analysts define business-friendly event labels after interaction data exists and explore how those behaviors affect conversion. Heap also has paid tiers with account analytics, alerts, AI, warehouse capabilities and services.

The distinction matters because organizations buy analytics for different reasons. A team that already trusts its event model may get more value from connected experiments. A team routinely blocked by missing events may gain more from broad capture and retrospection. Neither approach excuses weak definition of an activated customer, churned account, completed purchase or important KPI.

Heap is part of Contentsquare: do not mix package names

Contentsquare acquired Heap and publicly integrates Heap's capabilities in its Product Analytics offering. A buyer may therefore see the standalone Heap pricing page, a Contentsquare pricing page, and sales-led Experience Platform bundles. These pages describe related technology but not necessarily identical contracts, inclusions or historical access.

The standalone Heap page lists up to 10,000 monthly sessions on Free and six months of historical data, while Growth adds 12 months. Contentsquare's newer packaging includes separate Experience Analytics offers with larger free-session allocations and different features and data windows. Never state that a Heap Free buyer automatically receives Contentsquare Experience Analytics Free's allowance, or that every Contentsquare replay feature is included in Heap Free.

Before signing, request a written SKU and feature schedule: the named product, session quota, history window, number of projects, data region, replay entitlement, AI features, warehouse connectors and renewal model. That is more reliable than combining the strongest bullet from each marketing page.

Amplitude pricing: Free and Plus

Amplitude Free is a permanent $0 tier with two million tracked events per month and unlimited team seats. Its current matrix lists core analytics, AI Agents and MCP, ten thousand monthly Session Replays, limited experimentation/guides and surveys, and one year of data access. Feature-specific limits apply; Free is not an unlimited Enterprise workspace.

Amplitude Plus also starts at $0 because the first two million monthly events are included. It supports usage above that threshold through a live event-volume estimator, up to the published self-service Plus scale. Plus adds capabilities such as custom events and formulas, 20 behavioral cohorts, alerts, heatmaps and two-year data access. Replays remain 10,000 a month on its baseline matrix, with other options depending on the package.

The $0 entry label is not a promise that a growing Plus deployment will stay free. Pricing beyond the allowance changes with counted event volume; do not substitute an old, universal price per 1,000 events or an outdated monthly-tracked-user calculator. Use the current pricing estimator with the intended instrumentation and expected seasonal peaks.

Amplitude Growth and Enterprise

Growth is a custom-priced event-based tier for organizations that need deeper behavioral exploration, monitoring, SSO and project permissions. The current pricing page lists 20,000 monthly session replays at the baseline tier and additional Agent Analytics capacity. Advanced analysis and support may justify its price where a growing organization already uses analytics for high-impact decisions.

Enterprise is also custom-priced. It adds advanced user administration, data access controls, stronger governance, unlimited monitoring and alerts in the pricing matrix, and 50,000 monthly Session Replays before any relevant expansion. Dedicated customer management and other enterprise support terms should be checked in a signed order.

Amplitude advertises a one-year Growth scholarship for qualifying early-stage startups with less than $10 million in funding and fewer than 20 employees. Eligibility and what happens after that period matter; a free-year promotion is not a permanent rate. Also model expansions in session replay, activation, experimentation and AI separately where product-specific add-ons are billed.

Heap pricing: Free and Growth

Heap's standalone Free tier lists $0 and up to ten thousand monthly sessions. It includes core analytics charts, enrichment sources, Guides integrations, six months of historical data and SSO. A product with modest traffic can use it to evaluate the experience of working from captured interactions without buying an enterprise contract.

Heap Growth lists no universal numerical public monthly fee. Instead, the pricing flow asks the prospective customer to sign up and install the tracking snippet to obtain an estimate. Growth adds Contentsquare Sense AI features, unlimited users and reports, chart customization, CSV exports, a 12-month historical window and email support. It would be inaccurate to name a dollar price for Growth without a current vendor-specific estimate.

Session counts, not the volume of every separately captured event, form the principal commercial baseline. Ask what happens when sessions exceed the tier threshold, what constitutes billable sessions across website and app properties, and whether annual contracts, minimums, overages or cancellation notice apply.

Heap Pro and Premier: custom pricing and add-ons

Heap Pro uses custom session pricing and extends Growth with account analytics, an engagement matrix, report alerts and standard support. Its pricing page places Session Replay in an add-on category. Do not describe replay as included at no extra charge merely because the feature appears in the product portfolio.

Heap Premier also uses a custom session contract. Its published positioning adds data warehouse integration, behavioral targeting, unlimited projects, advanced user permissions, dedicated customer success management and region-specific storage. Its Session Replay is likewise shown as an add-on on the standalone page.

The difference between Pro and Premier may come down to governance, project structure or warehouse needs more than daily chart usage. Request quotes for a comparable number of projects, sessions, users and years of retention, and distinguish one-time implementation from recurring subscription charges.

Events versus sessions: why headline quotas cannot be directly compared

An Amplitude event is a tracked action: opening an application, viewing a page, clicking a button or completing a purchase. A Heap session represents a period of activity by a visitor or user, within the product's session definition. One session can contain one event or hundreds. There is no fixed conversion from two million events to ten thousand sessions.

Consider a hypothetical site with 8,000 monthly sessions and an average of 30 Amplitude-tracked events per session. That implies about 240,000 events, within the displayed Free limits of both products. With 50,000 sessions and 60 tracked events per session, the model becomes three million events. Both free allowances are exceeded, even though the tools measure different things. These numbers are illustrative arithmetic, not measured benchmarks or vendor prices.

A product team should instrument both candidates on a limited consented pilot, calculate daily sessions and events, then forecast at least a full year's growth. Include fluctuations after campaigns, product launches and changes to automatic capture, which can dramatically alter event totals.

Autocapture: Heap remains strong, but Amplitude supports it too

Heap pioneered a capture-first approach in which a snippet automatically records many clicks, taps, pageviews, form interactions and related browser behavior. Because those interactions are stored when they occur, a later analyst can attach a human-readable definition to previously captured behavior without asking engineering to redeploy tracking for every new question.

Amplitude now documents Autocapture across Browser, iOS, Android and Flutter SDKs, as well as visual labeling for previously captured web clicks. Its published browser schema includes page views, session starts and ends, form starts/submissions, element clicks or changes, file downloads, and configurable additional signals. It is therefore wrong to describe modern Amplitude as strictly manual instrumentation.

Where Heap still deserves careful consideration is the analyst-centered workflow for retrieving previously unplanned interaction evidence. Where Amplitude may be preferable is when captured UI events, carefully instrumented business events, experimentation and activation all need to operate in one governed platform. Test the same scenarios, selectors, dynamic components and cross-device identity rather than relying on a binary feature checklist.

Retroactive event definition is not time travel

Heap can let analysts define an event after the customer action happened if its instrumentation was already collecting that interaction and the underlying history remains available. It cannot recover a click from before the snippet was installed, an action it did not capture or data older than the retained window. Historical reconstruction also becomes harder if a site's markup changed and selectors no longer map cleanly.

Amplitude likewise supports retroactive visual labels for captured interactions and query-time transformations of data it has already received. The official transformations documentation describes retrospectively merging event names or properties without changing raw stored events. These are powerful analytical conveniences, but they cannot manufacture a confirmed purchase that never arrived from a server or browser.

If a business must analyze payment success, subscription cancellation, invoice status or seat entitlement, it should deliberately capture server-side facts in either platform. Autocapture is a complement to an accurate business-event specification, not a substitute for it.

Tracking plans, naming and governance

The greatest analytics risk is not an empty chart; it is a believable chart built from inconsistent definitions. Teams should define user identity, account identity, event names, event properties, revenue attribution, conversion windows and exclusion rules before comparing funnel rates. A sign-up button click should not silently become the team's official completed-signup metric.

Amplitude offers data planning, schema governance, transformations and access controls with capabilities by plan. Heap allows analysts to organize automatic interactions into defined events, but broad capture can generate overlapping interpretations such as checkout clicked, checkout started and checkout page viewed. An owner should certify which event serves as the reporting source of truth.

Use a small controlled taxonomy with event owners, descriptions, examples, expected volumes and test cases. Audit it after important releases, app navigation changes and privacy updates. That discipline improves both products more than another dashboard template would.

Funnels and conversion analysis

Both platforms can build multi-step funnels around activation or purchase. For a SaaS onboarding flow, that might be account created, workspace connected, teammate invited and first report delivered. For ecommerce, it might be product viewed, cart opened, shipping completed and payment confirmed. Both can segment those steps by customer context when the necessary attributes exist.

Heap's analysis is especially attractive when an analyst realizes that a particular click or navigation sequence matters only after a drop-off has emerged. Previously captured behavior may let the team construct additional funnel steps without waiting for a new collection cycle. Heap's Illuminate and journey tooling provide further behavioral exploration depending on plan.

Amplitude's advantage emerges when funnel findings can immediately inform a test, rollout, cohort, in-product guide or activation workflow. Choose based on the entire decision cycle, not just whether the funnel is drawn as a chart.

Retention, engagement and cohorts

Amplitude has mature retention analysis, segmentation and behavioral cohort workflows that are closely connected with experiments and downstream activation. A subscription software team can study whether inviting a colleague within three days predicts later retention and then use that finding to target a guided onboarding message or an experiment.

Heap offers retention, segmentation and behavioral exploration grounded in captured actions. That can expose unexpected usage patterns such as users repeatedly returning to a particular configuration page before upgrading. Its account-analytics and engagement features become stronger in higher tiers.

Neither product can determine customer retention accurately unless identity is stable and meaningful actions are defined. A returning anonymous browser cookie and a returning paid business account are not the same unit. Specify whether retention means a user, active workspace, paying company or completed recurring task.

Journeys and friction analysis

Heap has a compelling story around discovering journeys that were not planned in advance. Its captured interactions let analysts inspect how people move through pages and controls, build paths and investigate conversion blockers. A product designer who cannot get another engineering sprint for instrumentation may see faster time to a useful answer.

Amplitude offers journey analysis as well as deeper behavioral analysis on applicable plans. Its ability to connect paths to funnels, retention and user cohorts is useful when an organization already uses the same product-data layer for experiments and feature rollouts.

Evaluate whether each platform identifies the same frustrating loop in a real test: repeated form submission, navigation backtracking, failed search, page errors or multi-step abandonment. Vendor screenshots are not a substitute for this task-based evaluation.

Session Replay: a meaningful packaging difference

Amplitude's current public pricing includes ten thousand monthly replays on Free and Plus, twenty thousand on Growth and fifty thousand on Enterprise, before paid expansion where available. Its Replay documentation describes linking recordings to analytics charts, masking sensitive content and investigating concrete experiences behind behavior metrics.

Heap's standalone pricing table identifies Session Replay as an add-on for Pro and Premier. Contentsquare's wider Experience Analytics products have different replay packaging, which must not be silently imported into a standalone Heap pricing comparison. The purchaser should request an entitlement table for recordings, retention, targeting and any consent prerequisites.

Replay is helpful for discovering layout defects and user frustration, but it is not a substitute for aggregates. A few unusual recordings can bias decisions, so follow up with funnel frequency, affected-user counts and business impact. Also test masking and exclusion rules before capturing production sessions.

Heatmaps, surveys and experience feedback

Amplitude currently lists heatmaps on Plus and broader guides, surveys and feedback features across its platform with use and plan limits. These can help product teams pair numerical behavior with direct user sentiment, then decide whether a change deserves a controlled experiment.

Contentsquare is known for experience analytics, heatmaps, replay and voice-of-customer tools, but a Heap buyer should not assume the entire Contentsquare Experience Analytics bundle is included. Heap's standalone pricing lists Guides integrations, while the wider family sells related products with different entitlements.

For a team requiring scroll maps, rage-click diagnostics, in-app survey targeting and feedback response analysis, create a line-by-line contract comparison. Distinguish native features, integrations, add-ons and separate SKUs.

A/B testing and feature flags: Amplitude has the clearer native path

Amplitude Experiment supports feature-flag rollouts, controlled product A/B tests and web experiments. Teams can target cohorts, split traffic, define success metrics from their analytics events and decide whether to expand, revise or roll back a change. Experiment capabilities and volume limits vary by plan, and specialized experiments for guides and surveys can require add-ons.

Heap delivers analytics that can inform experiments, but its standalone offer is not a direct feature-flagging or full experiment-management replacement. Teams using Heap may connect a specialized tool for rollout and use consistent user IDs to analyze outcomes. That can be an effective architecture, but it introduces integration and governance effort.

If the buyer's primary objective is to go from insight to test to new experience without moving between tools, Amplitude has a stronger documented end-to-end story. If the organization already runs a mature experimentation platform, Heap's analytics specialization may be more important than duplicating native test controls.

AI features and their limits

Amplitude markets AI Agents, MCP access, analytics assistance and related agent or feedback products on current plans. Specific Agent Analytics sessions, feedback records, querying privileges and other limits differ by tier. AI can help formulate queries or summarize signals; it does not automatically validate every event definition or prove causation.

Heap Growth and higher standalone plans advertise Contentsquare Sense AI capabilities. Depending on the account, AI assistance can speed up navigation through behavioral questions and interpretation of product usage. A buyer must verify exactly which AI surfaces and usage limits are enabled under the chosen Contentsquare package.

A sensible evaluation asks each assistant to explain the same funnel change, identify the source events and filters, and show a reproducible chart. If the answer cannot be traced to reliable measurement, faster prose is not better analytics.

Web, mobile and cross-platform measurement

Amplitude documents web, iOS, Android and Flutter SDKs with automatic collection options, making it suitable for teams that need product behavior across devices. A product with mobile onboarding followed by desktop administration can attach consistent identified-user context, provided implementation and consent rules are designed correctly.

Heap publishes web and mobile measurement capabilities and positions autocapture as central to the experience. The exact automatically recorded action types, mobile SDK limitations and identity behavior still require confirmation on the planned operating systems and software versions.

Test the complete journey: first anonymous visit, install or open, sign-in, checkout, logout and reactivation on another device. Ensure sessions, users and businesses are not double-counted when identities merge.

B2B account analytics and group behavior

In B2B SaaS, measuring one person's repeated visits may be less useful than measuring workspace or account adoption. Amplitude documents group and account analytics capabilities with plan-dependent controls, enabling teams to consider which companies successfully activate several departments or teams.

Heap Pro lists account analytics, and Premier extends collaboration and enterprise governance. Heap can therefore be a serious option for organizations whose customers are businesses rather than individual consumers.

The prerequisite is a correct account identifier passed from the application, plus consistent ownership of multi-workspace users. An event tagged only with an anonymous device cannot reliably establish whether a customer organization is expanding or churning.

Marketing attribution and revenue measurement

Both tools can help connect product behavior to acquisition campaigns if campaign parameters and user data are collected consistently. Amplitude includes product and web analytics and campaign reporting with entitlements by tier. It may be particularly attractive to teams that want acquisition cohorts to flow into experiments, activation and lifecycle journeys.

Heap is oriented more directly toward what visitors do within digital experiences; its strengths in click paths, conversion and friction can support landing-page and checkout improvement. It should not be presented as a complete native advertising attribution system merely because it knows that a visitor clicked a page element.

For paid media reporting, it may still make sense to operate a separate marketing analytics product alongside either platform. Reconcile conversions, consent effects, attribution windows and revenue amounts before comparing channel return.

Integrations, activation and warehouse access

Amplitude provides SDKs, APIs, data pipelines, cohort destinations and platform integration options. Its model is increasingly to move governed cohorts and event insights into experiments, guides or external tools. Access to particular connectors, real-time streaming, data controls and scheduled syncs can depend on plan or add-on.

Heap offers a broad integrations ecosystem and its Premier pricing highlights data warehouse integration. Snowflake, BigQuery and other storage systems may be part of an approved architecture, but licensing a warehouse integration does not include warehouse storage, data engineering or downstream compute bills.

List the actual systems that must share identifiers and properties: CRM, customer support, payment provider, CDP, experimentation, warehouse and marketing automation. A generic catalog count is less useful than a verified and supportable path for the five integrations the company truly needs.

Privacy, consent and sensitive-data handling

Autocapture increases the need to understand what behavioral and element data is collected. Review consent laws and regulatory obligations by jurisdiction, mask or exclude form values and personal information, and never assume a default setting is automatically sufficient for your business. Both platforms need privacy review before deploying high-volume interaction capture.

Amplitude's documentation includes user and event schema controls, replay masking and region-related capabilities. Heap's replay help describes the categories of activity captured and explains that input-field contents are not captured by default, with further page and element exclusions available. Verify settings against a real application with health, financial or credential fields.

Govern user deletion, data retention, subprocessors, cross-border processing and who can export data. If a tool records an event before a consent signal is honored, a polished privacy policy does not repair the engineering error.

Data history, retention and reporting continuity

Amplitude's current pricing matrix describes one year of data access on Free and two years on Plus, with longer or different enterprise entitlements at higher tiers. Replay retention is a separate dimension: the current baseline matrix lists one month, with add-ons for longer periods on eligible plans.

Heap standalone Free lists six months and Growth twelve months of analytics history, with longer historical options on higher levels. Some Contentsquare product analytics tables show a different window, and that discrepancy is precisely why buyers must verify the named plan rather than republish a blended allowance.

If the company studies seasonal retention or annual renewal cohorts, a six-month window may be insufficient. Plan for data warehousing or other approved archival strategy before the analysis period disappears, and test whether raw exports preserve the fields needed for future reconstruction.

Ease of setup: snippet is not the whole implementation

For a first web-only pilot, Heap's snippet and automatic capture can reduce the amount of custom tracking code needed before useful exploration. The analyst may begin defining events from observed behavior quickly. That strength can matter for a marketing-led product team without dedicated analytics engineering.

Amplitude can also start with SDK-based autocapture, but extracting its full value from experimentation and activation benefits from a carefully designed event model, identity strategy, rollout SDKs and trustworthy server-side outcomes. The process takes effort, yet it builds a repeatable platform for several teams.

Neither system is fully installed just because data points appear on a dashboard. Validate event semantics, mobile parity, time zones, authenticated identities, consent, bot filtering, and schema drift before executives rely on the reports.

Which is better for an early-stage SaaS startup?

A startup looking to understand activation without a large analytics budget has two compelling free starting points. Amplitude allows up to two million events per month with unlimited seats and access to several growth tools at limited volumes. Heap allows ten thousand monthly sessions and an appealing broad-capture approach.

Choose Amplitude when the founder plans to run feature tests, onboard cohorts and activate users from the same analytics layer. Choose Heap when the first urgent problem is understanding the exact pages and controls users touch and the team cannot predict in advance which interactions will matter.

A startup may outgrow either free tier quickly. Forecast actual sessions and events, compare costs after the allowance, and confirm which experiment or replay features remain available on the selected paid tier.

Which is better for a growing B2B product?

A growing B2B business has more than onboarding conversion to measure. Sales and customer success need workspace activation, account-level usage, feature adoption, expansion indicators and reliable company identity. Either platform can contribute if the account model is designed well.

Amplitude's connected experiments, behavioral cohorts and activation may work best when a product-led growth team needs to run an ongoing optimization program. Heap Pro account analytics can appeal to teams whose biggest challenge is learning from complex customer journeys captured automatically.

The deciding proof of concept should include an account hierarchy, several users per account and a permission-sensitive journey. Test the cost of adding SSO, governance, historical access and necessary integrations before selecting a multi-year contract.

Which is better for ecommerce and conversion optimization?

Ecommerce teams care about purchase funnels, repeat buying, checkout friction, product discovery, promotions and revenue outcomes. Heap's broad behavioral collection can reveal unexpected clicks and abandonment paths in storefront interfaces. Those insights are useful when the team modifies pages frequently or relies on third-party plugins.

Amplitude adds a stronger direct path toward testing conversion improvements and activating audiences, especially if the same team runs campaigns and in-product experiments. Accurate revenue and order-completion tracking still require authoritative commerce events rather than just browser button clicks.

If marketing attribution is central, pair the product platform with an appropriate campaign measurement system rather than assuming either replaces it. Ask for a demo based on abandoned checkout, repeat customer purchases and one testable conversion hypothesis.

Which is better for UX research and usability teams?

A UX research team may value behavioral context more than a marketing attribution dashboard. Heap's focus on retroactive events and journeys is attractive when researchers pose new questions after observing a confusing navigation pattern. It can reduce turnaround time between a qualitative finding and quantitative validation.

Amplitude's Session Replay integration and analytics-to-experimentation workflow are attractive when researchers help select a design change, compare treatment and control, and measure whether task completion improved. It can turn a usability observation into a measurable product decision.

Whichever platform is used, preserve qualitative interviews and accessibility testing. Click behavior alone cannot prove what a user intended or whether an interface was comprehensible to people using assistive technology.

Which is better for regulated or privacy-sensitive teams?

Both platforms may serve organizations with governance needs, but suitability must be established through current contracts, security documentation, data flow review and privacy configuration. Evaluate data region, deletion APIs, encryption, user roles, support for SSO, replay masking and restrictions on collected fields.

Amplitude offers stronger enterprise governance options in its Growth and Enterprise tiers. Heap Premier advertises more advanced permissions and region-specific storage. These are useful checklist items, not an automatic certification that every workload or regulation is supported.

Make the final decision with the legal, security and engineering teams. A no-code installation that collects restricted information incorrectly can create more risk than an explicitly controlled server-side integration.

Illustrative cost scenario: smaller web product

Assume a business records 6,000 sessions per month and 40 Amplitude events per session, for roughly 240,000 events. Both Free plan allowances are large enough at this modeled usage. That does not establish that the products are equivalent: the buyer still needs to compare analysis history, replay, experiments, team workflow and privacy requirements.

If actual event volume is closer to 200 events per session, the same traffic creates 1.2 million events, still under Amplitude's two-million Free cap, while Heap remains under ten thousand sessions. This demonstrates how rich autocapture can change event volume without changing the number of visitors.

No subscription cost should be invented for this scenario beyond the published free allowances. Other costs include implementation, engineering checks and optional data storage or services.

Illustrative cost scenario: high-engagement product

Consider 30,000 monthly sessions with 100 separately recorded Amplitude events each. This produces three million monthly events. Amplitude Free would be exceeded and Plus would require an estimate from the current live calculator. Heap's ten-thousand-session Free limit would also be exceeded; Growth would require a vendor estimate.

If the same team intentionally reduces redundant Amplitude events to 40 per session, the modeled Amplitude volume becomes 1.2 million. That could bring the usage under the free event threshold, although recording fewer events is worthwhile only if essential analytics questions remain answerable. Heap session counts would be unchanged in this example.

This is why cost modeling cannot be based on monthly visitors alone. The correct calculation comes from actual instrumented event volume, session definitions, free thresholds, contracted retention and required add-ons.

Illustrative cost scenario: multiple products and business units

A company with three applications, different data regions, dozens of analysts, account-level reporting and multiple business units may need features that neither free plan provides. Amplitude Growth or Enterprise may be appropriate for SSO, access control and cross-product analysis. Heap Premier may be appropriate for unlimited projects, warehouse integration and stronger governance.

The procurement exercise should compare two tailored quotes. For Amplitude, forecast events and product-specific replay or activation add-ons. For Heap, forecast counted sessions, projects, history, replay add-ons, warehouse access and services. Both quotes should specify renewal and overage behavior.

A single per-month headline figure would conceal critical differences, so avoid publishing a numeric winner without those quotes.

Migration from Heap to Amplitude

A migration should begin with an inventory of Heap's defined events, captured interactions, data properties, identities, account hierarchies, dashboards and integrations. Separate interactions that can be reproduced using Amplitude autocapture and visual labeling from business events that require explicit server-side instrumentation.

Implement Amplitude alongside Heap long enough to compare the same funnel and active-user numbers. Differences may come from session boundaries, identity stitching, selection of event filters or how UI changes affect automatic capture. Do not turn off Heap until required historical reports, alert owners and operational workflows have been replaced.

Heap's historical raw activity does not automatically appear in Amplitude merely because the new SDK is installed. Check official import paths and historical storage before promising seamless migration or chart parity.

Migration from Amplitude to Heap

Start by classifying Amplitude events into automatically capturable interactions and authoritative business events. Confirm how to replicate the second group using Heap's supported custom event and identity mechanisms, especially purchases, subscriptions, cancellations and customer-account roles.

Rebuild key funnels and retention cohorts in Heap with consistent time zones, measurement windows and cohort membership. Use a side-by-side period to identify discrepancies between amplitude event counts and Heap session-oriented reporting rather than assuming numbers will match exactly.

Also identify any lost platform functionality. If the company currently depends on Amplitude Experiment, feature flags, activation or Guides, it may need separate tools after the move. The purchase decision should include the cost and operational risk of replacing those workflows.

Can a business use both tools?

It is possible to run Amplitude and Heap together, particularly during a migration or when different teams have distinct needs. Heap might support rapid behavioral exploration while Amplitude supports governed experiments and product activation. Such a setup can be useful in a complex company but should be justified by specific decisions each tool enables.

Dual measurement has real costs: duplicated SDK or tag complexity, consent configuration, differing active-user definitions, additional privacy surfaces, inconsistent event governance and the time analysts spend reconciling figures. Choose a source of truth for each KPI and document why the second platform exists.

If a team cannot describe which question requires each product, it probably should not pay for both long-term.

Implementation checklist before you buy

Choose three important business questions before opening trials: where activation breaks, which product behavior predicts retention, and whether a specific product change improves conversions. Identify the minimum verified events and properties needed for each question. Include server-authoritative outcomes rather than just clicks.

Set up a consented pilot with staging and production separation. Compare automatic collection coverage, mobile and web identity, conversion results, replay masking, analyst effort and how much time a new question takes. Measure actual monthly event and session usage after excluding test traffic and duplicates.

Finally request the exact contract entitlements and a forecast at six, twelve and twenty-four months. Confirm historical retention, support, add-ons, cancellation notice, renewal increases and export access. The best tool is the one that reliably answers important questions with sustainable cost and data stewardship.

Strengths and tradeoffs in practice

Amplitude advantages include a large permanent free event allowance, unlimited seats, a more unified platform for analysis and action, and native experimentation and activation. Its tradeoffs include potential event-volume cost escalation, growing product complexity, and higher-tier access requirements for SSO, advanced governance and certain data capabilities.

Heap advantages include automatic interaction capture, flexible retroactive event organization, journey exploration and strong appeal to teams that are frequently blocked by missing events. Its tradeoffs include lower public pricing transparency for paid tiers, data-overload and taxonomy risks, and replay or warehouse capability depending on an add-on or higher package.

Neither vendor's competitive marketing should settle the decision. Both have autocapture; both support useful product funnels. A fair comparison checks the full workflow, the exact SKU and source-of-truth measurement rather than claims that one provider completely lacks a familiar chart.

Final recommendation: choose by the decision cycle

Choose Amplitude when product, growth and engineering teams intend to measure usage, create segments, test new features and target follow-up experiences as one repeatable operating cycle. It is particularly compelling for growth teams that value a broad free plan and want one shared set of behavioral metrics across analytics, experimentation and activation.

Choose Heap when you need to investigate previously unanticipated user behavior, reduce dependence on a developer for every UI interaction event and understand unexpected paths through a website or application. It is strongest where capture-first investigation materially speeds decisions and the Contentsquare package matches the team's actual needs.

Run a parallel trial when the decision is consequential. Time the three real questions, compare reliable answers and forecast both billing units at the planned scale. No universal product winner exists independent of data quality, workflow priorities, compliance obligations and price quote.

How Toollers prepared this comparison

We compared current public pricing and vendor documentation from Amplitude, Heap and Contentsquare, then checked both live Toollers tool profiles and related Review, Pricing and Alternatives resources. We emphasized concrete constraints such as free event/session allowances, add-on entitlements, retroactivity limits, experimentation capabilities and tier-dependent governance.

This is a research-based buying guide, not a laboratory benchmark. We did not operate both platforms against the same customer dataset or verify independent query timings, uptime, support response, data accuracy, conversion lift or sales quotes. Such outcomes depend on implementation details and cannot responsibly be invented.

Pricing and packaging change. Recheck the live Amplitude pricing, Heap pricing and Contentsquare pricing pages before committing to a purchase.

Frequently asked questions

Is Amplitude or Heap better for SaaS product analytics?

Amplitude often fits SaaS teams that want connected behavioral analysis, experimentation, feature flags, activation and AI. Heap is compelling when product analysts need automatic interaction capture and flexible historical behavioral exploration. The right choice depends on workflow, governance and costs.

How much does Amplitude cost?

Amplitude Free provides two million events per month at $0. Plus starts at $0 for its first two million monthly events, then scales with event volume through a live estimator. Growth and Enterprise require custom quotes. Add-ons and replay limits can affect the total bill.

How much does Heap cost?

Heap Free supports up to 10,000 monthly sessions. The standalone Growth offer requires a usage-informed estimate after installation, while Pro and Premier have custom session pricing. There is no universal official numeric paid entry price on the current standalone pricing page.

Does Amplitude have autocapture?

Yes. Modern Amplitude supports Autocapture for common web and mobile interactions and visual labeling for previously captured clicks. Some business outcomes still require deliberate server-side instrumentation and a sound tracking plan.

Can Heap define events retroactively?

Yes, when the relevant interaction was automatically captured and remains in the retained historical data. It cannot create activity that was never collected or that predates instrumentation.

Which platform is better for A/B testing?

Amplitude has a clearer native experimentation system with feature flags, web tests and behavioral metric integration, subject to plan limitations. Heap can measure experiment outcomes but its standalone platform is not an equivalent native full experiment-management suite.

Which platform has a more generous free plan?

The free quotas measure different things: Amplitude includes two million events per month, while Heap includes ten thousand sessions per month. Compare projected event volume, session counts and required features rather than converting the limits directly.

Does Heap include session replay for free?

The standalone Heap pricing matrix lists Session Replay as an add-on for Pro and Premier, not as a universally included Free entitlement. Other Contentsquare experience products have different replay packaging, so verify the named contract.

Is Heap the same thing as Contentsquare?

Heap is part of Contentsquare and its capabilities appear in Contentsquare Product Analytics. Standalone Heap plan descriptions and newer Contentsquare Experience Analytics offers are not identical, so buyers should confirm the SKU, quotas, history and add-ons.

Can Amplitude change historical event data?

Amplitude supports query-time transformations and retroactive visual labels for data already captured. That does not invent missing source events or rewrite raw warehouse exports; historical corrections have defined limits.

Can a company use Amplitude and Heap together?

Yes, but teams should designate which system owns each KPI, implement consistent consent and identity rules, and justify duplicated collection and cost. Running both is often sensible during evaluation or migration.

Which should I choose for a small startup?

Start with Amplitude Free when you want a broad analytics-plus-experimentation foundation and can keep event volume within its allowance. Try Heap Free when capturing many interactions with minimal planning is the urgent need. Re-evaluate paid pricing using measured events and sessions.
