Stay free if you only need up to 10,000 monthly sessions and 6 months of data history. Upgrade if you need advanced analytics including heap illuminate and session replay add-on available. Most solo builders can start free.
Why it matters: Auto-capture generates massive data volumes which can drive significantly higher costs at scale compared to intentional event tracking approaches

Why it matters: Session replay and Heap Connect are paid add-ons rather than included features in lower tiers, increasing the effective price for full functionality

Why it matters: Free tier is limited to 10,000 monthly sessions and 6 months of data history — restrictive for products beyond early-stage validation

Why it matters: Contentsquare integration means Heap's roadmap is increasingly tied to the parent company's strategy, creating uncertainty about long-term standalone direction

Why it matters: Pricing is not publicly listed for Pro and Premier plans, requiring sales conversations that slow procurement compared to self-serve competitors

Heap's lightweight JavaScript SDK (or mobile SDK) records every user interaction — clicks, taps, page views, form changes, and field inputs — automatically when installed via a single snippet. Each interaction is captured with rich contextual metadata like element properties, page URL, DOM hierarchy, and user attributes. You can then retroactively define events and build analyses on any captured interaction, even months after it occurred. This contrasts with traditional analytics tools where you must define and instrument events before they can be measured, missing any behavior you didn't anticipate tracking.
Heap's SDK is designed to be lightweight and asynchronous, loading after page-critical resources and minimizing performance impact. For most websites the impact is negligible — typically under 50ms added to page load. However, for very high-traffic sites or performance-sensitive mobile applications, it's worth testing the SDK's impact during implementation. Heap provides configuration options to exclude certain pages, throttle event capture, or disable specific interaction types if needed for performance optimization.
The key difference is Heap's auto-capture vs Amplitude/Mixpanel's instrumented approach. Heap captures everything automatically enabling retroactive analysis, while Amplitude and Mixpanel require deliberate event tracking but offer more precise, intentional data collection. Amplitude has a more generous free tier (up to 50K MTUs) and stronger native experimentation features, while Mixpanel offers more flexible event-based pricing. Heap is favored by teams that want rapid time-to-insight without engineering dependencies, especially since the Contentsquare acquisition added integrated session replay and heatmaps.
Heap was acquired by Contentsquare in 2024 and now operates as the Product Analytics pillar of Contentsquare's Experience Intelligence Platform. Heap continues to operate as a product with its own pricing and plans, but customers gain access to Contentsquare's Sense AI, CoPilot, integrated session replay, heatmaps, and error analysis capabilities. Existing Heap customers can continue using the platform with these added features. The combined platform is positioned as the only solution offering complete visibility into both quantitative analytics and qualitative experience data in a single tool.
Heap offers four main tiers: a Free plan with 10,000 monthly sessions and 6 months of data retention, a Growth plan for early-stage startups, a Pro plan with advanced features and longer data history, and a Premier plan for enterprise needs with unlimited sessions and dedicated support. Session replay and Heap Connect (warehouse sync) are available as add-ons primarily on Pro and Premier plans. Specific pricing for Growth, Pro, and Premier tiers requires contacting Heap's sales team, which is standard for enterprise SaaS analytics platforms in this category.
