## Heap alternatives at a glance

| Alternative | Best for | Standout | Biggest weakness | Learning curve | Price |
| --- | --- | --- | --- | --- | --- |
| Heap (the incumbent) | product teams that want non-technical staff to build and adjust event funnels retroactively, without waiting on engineering to instrument new tracking code | Autocapture records every interaction from install without requiring events to be pre-defined, so teams can build new funnels against historical data instead of only data collected after an event was manually tagged. | Pricing above the 10,000-session free tier is not published; Growth, Pro, and Premier all require a sales conversation, and reviewers report costs climbing sharply as session volume scales, prompting some teams to switch at renewal. | Low | Free |
| Amplitude | product teams that need behavioral analytics, session replay, and lightweight experimentation in one tool, and prefer usage-based pricing tied to event volume over per-seat licensing | Bundles product analytics, session replay, and feature experimentation under one usage-based pricing model, plus native MCP connectivity so AI coding tools like Claude and Cursor can query product data directly. | Pricing above the free 2-million-event tier is usage-based and largely hidden behind "contact sales" for Growth and Enterprise, making it hard to budget for a scaling product without a sales conversation; heavy instrumentation can also drive event volume, and cost, up faster than teams expect. | Moderate | Free |
| Mixpanel | product teams tracking funnels, retention, and feature adoption across web and mobile without writing SQL | Behavioral cohorts and multi-touch attribution built on Mixpanel's proprietary Arb query engine, fast enough for ad hoc exploration across tens of millions of monthly events. | Growth-plan pricing is not published as a flat number; it scales with event volume through a calculator, which makes budgeting harder to predict than a fixed per-seat price, and event-based pricing can get expensive fast for high-traffic products compared to flat-rate competitors. | Moderate | Free |
| PostHog | product and engineering teams who want analytics, session replay, feature flags, and error tracking in one platform instead of stitching together separate tools | One platform combining product analytics, session replay, feature flags/A-B testing, error tracking, and a data warehouse, each billed on its own usage-based rate that drops at higher volume. | Usage-based pricing across many separate products (events, replays, flags, surveys, data warehouse rows) makes total monthly cost harder to predict than a single flat per-seat price, and some enterprise features live in a separate proprietary ('ee') license rather than the fully open-source core. | Moderate | Free |
| FullStory | product and UX teams who need to watch actual user sessions to diagnose friction, not just aggregate funnel metrics | Captures every session by default with no pre-defined event tracking, so teams can retroactively search and replay any past user behavior instead of only what they thought to instrument in advance. | Published pricing stops at the free 30,000-session tier — every paid plan (Business, Advanced, Enterprise) requires a sales quote, and reviewers on G2 and Capterra repeatedly cite cost jumping sharply once a site exceeds the free quota. | Low | Free |
| Contentsquare | enterprise and mid-market brands (retail, financial services, travel, B2B) that need AI-prioritized experience analytics across web and mobile without manual event tagging, and have budget for a custom enterprise contract | Automatic, no-tag capture of full user interactions combined with Sense, an AI agent that prioritizes which friction points to fix rather than leaving a human analyst to sift through raw heatmaps and session replays. | Pricing is entirely custom-quote with nothing published, so buyers can't self-serve a cost estimate the way they can with Hotjar or Mouseflow, and reviewers report that setting up webpage mapping and tracking variables requires significant initial effort and close coordination with development teams. | Moderate | Custom pricing |

## 1. Amplitude — best Heap alternative for product teams that need behavioral analytics, session replay, and lightweight experimentation in one tool, and prefer usage-based pricing tied to event volume over per-seat licensing

Amplitude is the best Heap alternative for product teams that want behavioral analytics, session replay, and lightweight experimentation bundled under one usage-based pricing model. Amplitude's Free plan covers up to 2 million tracked events per month with no credit card required, well beyond Heap's own free tier cap of 10,000 monthly sessions, and Amplitude holds a 4.6/5 rating from 68 Capterra reviews, edging out Heap's 4.5/5 from 42 Capterra reviews. Amplitude also ships native MCP connectivity so AI coding assistants like Claude and Cursor can query product data directly, a capability Heap's platform doesn't list, and its Plus plan scales usage-based pricing up to 70 million events/month with published mechanics, compared with Heap's Growth, Pro, and Premier tiers, which are all custom-quoted through sales with no published numbers. Heap is still the better choice for teams that specifically want to avoid instrumenting events at all: Heap's autocapture records every click, tap, and form submission from install with no manual event tagging, letting non-technical staff build brand-new funnels against historical data, while Amplitude's event tracking still relies on its SDKs (TypeScript, Python, Go, Swift, Kotlin) capturing what's been instrumented.

Compared to Heap: free tier covers 2M events/month vs Heap's 10,000-session cap, slightly higher Capterra rating (4.6/5 from 68 reviews vs 4.5/5 from 42), native MCP integration for Claude and Cursor

- Wins: Free tier covers 2 million events/month with no credit card, vs Heap's 10,000-monthly-session free cap · 4.6/5 rating from 68 Capterra reviews vs Heap's 4.5/5 from 42 Capterra reviews · Native MCP connectivity lets AI coding assistants like Claude and Cursor query product data directly, which Heap doesn't list
- Loses: No autocapture-by-default model; Amplitude's event tracking relies on SDK instrumentation rather than capturing everything automatically like Heap · Growth and Enterprise pricing is still usage-based and requires navigating a calculator or sales conversation for exact numbers, similar to Heap's own unpublished tiers · Setup and event-taxonomy design require more upfront planning than Heap's retroactive, no-instrumentation approach
- Pros: Free tier covers 2 million events/month with no credit card required, generous compared to many analytics competitors.; Session replay and feature experimentation are built in, reducing the need for separate tools.; Native MCP support lets AI coding assistants query product analytics data directly.; SDKs across TypeScript, Python, Go, Swift, and Kotlin cover most product stacks.
- Cons: Growth and Enterprise pricing is not published; both require a sales conversation to get a quote.; Usage-based pricing means costs can rise with instrumentation depth, not just company size or seats.; Advanced session replay volume (beyond the free tier's 10,000/month) requires moving to a paid plan.; Setup and event-taxonomy design require more upfront planning than simpler analytics tools.
- **Pricing:** Free (verified undefined NaN, NaN) — Free up to 2M events/month vs Heap's free tier capped at 10,000 sessions/month; both vendors' paid tiers are usage-based and not published as flat numbers
- Ratings: Capterra 4.6/5 (68 reviews)

## 2. Mixpanel — best Heap alternative for product teams tracking funnels, retention, and feature adoption across web and mobile without writing SQL

Mixpanel is the best Heap alternative for teams that want a genuinely forever-free tier with real usage headroom, rather than Heap's narrower 10,000-monthly-session free cap. Mixpanel's Free plan requires no credit card and covers up to 1 million events per month with 10,000 session replays included, and it holds a combined review base of 4.5/5 from 146 Capterra reviews and 4.9/5 from 90 Product Hunt reviews, more third-party review volume than Heap's 4.5/5 from 42 Capterra reviews. Mixpanel's proprietary Arb query engine is built for fast ad hoc queries across large event volumes, and MCP integrations connect Mixpanel data directly into Slack, Claude, ChatGPT, and Cursor. Heap is still the better choice for teams that don't want to plan an event-tracking taxonomy in advance: Mixpanel requires disciplined event naming up front, and poorly named events make later analysis messy, a setup cost Heap's autocapture model avoids entirely by recording every interaction from install and letting non-technical staff define funnels retroactively against historical data, without waiting on engineering to instrument new tracking code.

Compared to Heap: forever-free tier with 1M events/month and 10,000 session replays vs Heap's 10,000-session cap, more combined third-party reviews (146 Capterra + 90 Product Hunt vs 42 Capterra), proprietary Arb engine for fast ad hoc queries

- Wins: Forever-free tier (no credit card) covers 1M events/month plus 10,000 session replays, vs Heap's 10,000-monthly-session free cap · 146 Capterra reviews at 4.5/5 plus 90 Product Hunt reviews at 4.9/5, more combined review volume than Heap's 42 Capterra reviews · Proprietary Arb query engine enables fast ad hoc queries across tens of millions of monthly events
- Loses: Requires a disciplined event-tracking taxonomy set up in advance; poorly named events make later analysis messy, unlike Heap's no-instrumentation autocapture · No SQL access on lower tiers limits users who want warehouse-style custom queries directly · Growth plan pricing is usage-based and not shown as a flat number, similar to Heap's own unpublished tiers
- Pros: Free tier genuinely usable up to 1M events/month with core funnel and retention analysis included.; Fast ad hoc queries across large event volumes via the proprietary Arb engine.; Session replay and A/B testing built into the same product as the analytics.; MCP integrations connect Mixpanel data directly into Slack, Claude, ChatGPT, and Cursor.
- Cons: Growth plan pricing is usage-based and not shown as a flat number on the pricing page, making costs harder to forecast.; Event-based pricing can climb quickly for high-traffic consumer apps compared to flat-rate tools.; No SQL access on lower tiers limits users who want to run custom warehouse-style queries directly.; Requires disciplined event-tracking taxonomy up front; poorly named events make later analysis messy.
- **Pricing:** Free (verified undefined NaN, NaN) — Free forever up to 1M events/month vs Heap's free tier capped at 10,000 sessions/month; both vendors' paid tiers require a sales quote or usage calculator rather than published flat rates
- Ratings: Capterra 4.5/5 (146 reviews) · Product Hunt 4.9/5 (90 reviews)

## 3. PostHog — best Heap alternative for product and engineering teams who want analytics, session replay, feature flags, and error tracking in one platform instead of stitching together separate tools

PostHog is the best Heap alternative for engineering-led teams that want product analytics, session replay, feature flags, error tracking, and a data warehouse bundled in one MIT-licensed, open-source platform. PostHog's core is published on GitHub under the MIT license, with a dedicated posthog-foss repository for teams that want strictly open-source code, and its Free plan requires no credit card while covering 1 million analytics events, 5,000 session replays, and 1 million feature flag requests per month, more generous across more product areas than Heap's 10,000-monthly-session free cap. PostHog holds a 5.0/5 rating from 253 Product Hunt reviews, a far larger sample than Heap's 4.5/5 from 42 Capterra reviews, and teams can choose a US or EU cloud region or self-host it entirely. Heap is still the better choice for non-technical teams that want the simplest possible entry point: PostHog's breadth of bundled tools means a wider surface area to learn than Heap's single-purpose, no-code autocapture approach, and PostHog's usage-based pricing spans multiple separately billed products (events, replays, flags, surveys, warehouse rows), making total monthly cost harder to forecast than Heap's simpler free-then-custom-quote structure.

Compared to Heap: MIT-licensed open-source core with self-hosting option, larger review sample (5.0/5 from 253 Product Hunt reviews vs 4.5/5 from 42 Capterra reviews), free tier bundles analytics, replay, feature flags, and error tracking

- Wins: MIT-licensed, open-source core published on GitHub, with an official self-hosting option Heap doesn't offer · 5.0/5 rating from 253 Product Hunt reviews, far more review volume than Heap's 4.5/5 from 42 Capterra reviews · Free tier bundles analytics, session replay, feature flags, error tracking, and surveys, more product areas than Heap's free tier covers
- Loses: Breadth of bundled tools creates a wider surface area to learn than Heap's single-purpose, no-code autocapture approach · Usage-based pricing spans multiple separately billed products, making total monthly cost harder to forecast than a single free-then-custom-quote structure · Some enterprise features live behind a separate proprietary 'ee' license rather than the fully open-source core
- Pros: Combines analytics, session replay, feature flags, error tracking, and surveys in one platform.; Generous free tier: 1M analytics events and 5,000 session replays per month with no credit card required.; MIT-licensed core with source available on GitHub, plus a dedicated posthog-foss repository for strictly open-source use.; Choice of US or EU cloud region, or self-hosting.
- Cons: Usage-based pricing spans multiple products independently, making total monthly cost harder to forecast than flat per-seat pricing.; Some enterprise features are gated behind a separate proprietary license (the 'ee' directory), not the fully open-source core.; Self-hosting PostHog at scale requires more operational overhead than using the managed cloud.; The breadth of bundled tools (analytics, replay, flags, surveys, data warehouse) means new users face a wider surface area to learn than a single-purpose analytics tool.
- **Pricing:** Free (verified undefined NaN, NaN) — Free tier (1M events, 5,000 replays, 1M feature flag requests) vs Heap's free tier capped at 10,000 sessions/month; PostHog's paid usage starts at $0.00005/event, Heap's paid tiers are unpublished custom quotes
- Ratings: Product Hunt 5/5 (253 reviews)

## 4. FullStory — best Heap alternative for product and UX teams who need to watch actual user sessions to diagnose friction, not just aggregate funnel metrics

FullStory is the best Heap alternative for product and UX teams that need to watch actual user sessions to diagnose friction, not just review aggregate funnel metrics. FullStory's free FullstoryFree tier covers up to 30,000 monthly sessions and 12 months of data retention with no credit card required, three times Heap's own free-tier cap of 10,000 monthly sessions with only 6 months of history. FullStory also holds a much larger review base than Heap: 4.5/5 from 1,048 G2 reviews and 4.6/5 from 67 Capterra reviews, compared with Heap's 4.5/5 from just 42 Capterra reviews. StoryAI, FullStory's natural-language AI assistant, answers behavioral questions in plain language instead of requiring analysts to build a custom dashboard. Heap is still the better choice for teams that want SSO included on a genuinely free plan: Heap's free tier explicitly bundles SSO and unlimited enrichment sources, while FullStory's free tier description doesn't list SSO, and FullStory's paid Business, Advanced, and Enterprise tiers are entirely custom-quoted through sales, just as Heap's Growth, Pro, and Premier tiers are.

Compared to Heap: free tier covers 30,000 sessions/month and 12 months of history vs Heap's 10,000 sessions/6 months, far larger review base (1,048 G2 + 67 Capterra vs 42 Capterra), StoryAI natural-language querying

- Wins: Free FullstoryFree tier covers 30,000 monthly sessions and 12 months of retention, vs Heap's 10,000-session, 6-month free tier · 4.5/5 from 1,048 G2 reviews and 4.6/5 from 67 Capterra reviews, far more review volume than Heap's 42 Capterra reviews · StoryAI answers behavioral questions in plain language without requiring a custom dashboard build
- Loses: Free tier doesn't list SSO the way Heap's free plan explicitly includes it · Paid Business, Advanced, and Enterprise tiers are entirely custom-quoted, just like Heap's unpublished Growth, Pro, and Premier tiers · Mobile analytics is a separate add-on rather than included by default
- Pros: Retroactive session search finds and replays any past user behavior without pre-defining tracked events.; StoryAI answers behavioral questions in plain language instead of requiring a custom dashboard build.; Free tier covers 30,000 sessions/month and 12 months of retention with no credit card required.; Reviewers consistently rate the interface as intuitive enough for non-technical team members to use directly.
- Cons: No published pricing above the free tier; Business, Advanced, and Enterprise all require a sales quote.; Reviewers report costs escalate sharply once a site outgrows the 30,000-session free tier.; High-traffic sites generate enough session volume that finding actionable insights can become overwhelming.; Mobile analytics is a separate add-on rather than included by default.
- **Pricing:** Free (verified undefined NaN, NaN) — Free up to 30,000 sessions/month vs Heap's free tier capped at 10,000 sessions/month; both vendors' paid tiers require a custom sales quote
- Ratings: Capterra 4.6/5 (67 reviews) · Product Hunt 4.7/5 (3 reviews)

## 5. Contentsquare — best Heap alternative for enterprise and mid-market brands (retail, financial services, travel, B2B) that need AI-prioritized experience analytics across web and mobile without manual event tagging, and have budget for a custom enterprise contract

Contentsquare is the best Heap alternative for enterprise and mid-market teams that want AI-prioritized experience analytics across web and mobile, with a dedicated AI agent that drafts recommendations instead of leaving all analysis to a human. Contentsquare holds a 4.6/5 rating from 604 G2 reviews and 4.8/5 from 116 Capterra reviews, far more review volume and a higher score than Heap's 4.5/5 from 42 Capterra reviews, and its Sense AI agent bundles session replay, product analytics, error monitoring, and voice-of-customer feedback into one platform rather than requiring separate tools. Contentsquare serves 3,000+ customers, mostly enterprise and mid-market brands in retail, financial services, and travel. Heap is still the clearly better choice for smaller teams and anyone without enterprise budget: Contentsquare has no free tier at all, unlike Heap's free plan covering up to 10,000 monthly sessions and 6 months of history, and every Contentsquare price requires a sales conversation and demo, with initial setup for webpage mapping and tracking variables demanding significant effort and close developer coordination, a heavier lift than Heap's single-snippet install.

Compared to Heap: higher combined review base (4.6/5 from 604 G2 + 4.8/5 from 116 Capterra vs 4.5/5 from 42 Capterra), Sense AI agent drafts recommendations automatically, bundles session replay, product analytics, and voice-of-customer feedback in one platform

- Wins: 4.6/5 from 604 G2 reviews and 4.8/5 from 116 Capterra reviews, far more review volume than Heap's 42 Capterra reviews · Sense AI agent prioritizes friction points and drafts recommendations rather than leaving all analysis to a human · Bundles session replay, product analytics, error monitoring, and voice-of-customer feedback in one platform, more modules than Heap lists
- Loses: No free tier at all, unlike Heap's free plan covering up to 10,000 monthly sessions and 6 months of history · Every price requires a sales conversation and demo; no published tiers or numbers at all, unlike Heap's at least-documented free tier · Initial setup for webpage mapping and tracking variables demands significant effort and close developer coordination, a heavier lift than Heap's single-snippet install
- Pros: No-tag automatic capture removes the manual event-tagging overhead of traditional web analytics setup.; Sense AI agent prioritizes friction points and drafts recommendations rather than leaving all analysis to a human.; 4.6/5 rating from 604 reviews on G2 and 4.8/5 from 116 reviews on Capterra, with customer support quality rated 9.4/10.; Bundles session replay, product analytics, error monitoring, and voice-of-customer feedback in one platform rather than requiring separate tools.
- Cons: No published pricing; every quote requires a sales conversation, ruling out self-serve evaluation for budget-conscious teams.; Initial setup for webpage mapping and tracking variables requires significant effort and close developer coordination, per reviewers.; Some users report alerts break after a few weeks and need manual reconfiguration.; Positioned and priced for enterprise budgets, putting it out of reach for the small-business and solo-marketer segment that tools like Hotjar or Mouseflow serve.
- **Pricing:** Custom pricing — Contentsquare: custom quote only, no free tier; Heap: free tier up to 10,000 sessions/month, paid tiers also custom-quoted

## FAQ

### Is there a free alternative to Heap?

Yes — Amplitude (2 million events/month), Mixpanel (1 million events/month, forever free), and PostHog (1 million events plus 5,000 session replays) all offer free tiers more generous in volume than Heap's own 10,000-session cap.

### What is the closest alternative to Heap?

Amplitude, since it matches Heap's core positioning as a behavioral product analytics platform with session replay, a comparably free-friendly tier, and a slightly higher 4.6/5 rating from 68 Capterra reviews versus Heap's 4.5/5 from 42.

### Can Amplitude replace Heap?

Yes for most product analytics use cases, since Amplitude covers funnels, retention, and session replay with a larger free tier. Teams that specifically want zero-instrumentation autocapture should stay with Heap, since Amplitude still relies on SDK-based event tracking.

### Which Heap alternative has the best free tier?

PostHog and Mixpanel both offer roughly 1 million free monthly events — PostHog forever with no credit card plus 5,000 session replays, Mixpanel forever free with 10,000 session replays — more generous than Heap's 10,000-session cap.

### Why do people switch away from Heap?

The most-cited reason is unpublished pricing above the free tier: Growth, Pro, and Premier all require a sales quote, and reviewers report costs climbing sharply as session volume grows.

### Do any Heap alternatives include an AI agent for analysis?

Yes — FullStory's StoryAI and Contentsquare's Sense both use AI to answer plain-language questions or automatically draft recommendations about behavioral data, capabilities Heap's own listing doesn't describe.
