Is Flowsery a Heap alternative?

They serve overlapping but different use cases. Heap is a product analytics platform with auto-capture aimed at understanding in-app user behavior. Flowsery is a privacy-first web analytics tool for tracking website traffic, conversions, and funnels without cookies. If privacy compliance and lightweight tracking are priorities, Flowsery is the better fit.

What is auto-capture and does Flowsery have it?

Auto-capture means Heap records every user interaction (clicks, form submissions, page views) automatically without you defining events in advance. Flowsery uses explicit event tracking — you define what to track. The tradeoff is that auto-capture collects more data but adds script weight and requires cookies, while explicit tracking is lighter and more privacy-friendly.

Does Heap require cookie consent?

Yes. Heap uses cookies for user identification and session tracking. Under GDPR and ePrivacy regulations, this requires a cookie consent banner. Users who decline cookies will not be tracked, which can lead to undercounting. Flowsery does not use cookies and tracks all visitors without requiring consent.

How does Heap's free tier compare to Flowsery's?

Both offer free tiers with 6 months of data retention. Heap's free tier allows up to 10,000 monthly sessions with core analytics. Flowsery's free tier allows up to 5,000 monthly events with a real-time dashboard, goal tracking, and unlimited sites. Flowsery's free tier does not require cookies and includes published upgrade paths.

Which is better for a content or marketing website?

Flowsery. Content and marketing websites benefit from lightweight scripts, cookie-free tracking, and web analytics dashboards that show traffic sources, top pages, geographic data, and conversion funnels. Heap's auto-capture is better suited for product analytics inside web applications.

TL;DR

Heap (now part of Contentsquare) is a product analytics platform known for its auto-capture approach — it tracks every user interaction automatically so you can analyze behavior retroactively without instrumenting events upfront.

Heap is the better choice if you want retroactive product analytics with auto-captured data and AI-powered insights.

Where Flowsery Wins

Cookie-Free Privacy Compliance

Flowsery never uses cookies and never requires a consent banner. Heap uses cookies and requires a cookie consent banner under GDPR and ePrivacy regulations. This means Heap may undercount visitors who decline consent.

Minimal Performance Impact

Flowsery's sub-1 KB script loads instantly and has negligible impact on page speed. Heap's auto-capture SDK is significantly heavier because it instruments and records every interaction on the page, which can affect load times and Core Web Vitals.

Transparent Pricing

Flowsery has clear, published pricing with a free tier and straightforward paid plans. Heap's pricing beyond the free tier is not publicly listed — you need to contact sales for Growth, Pro, and Premier plans.

Longer Free Tier Retention

Flowsery's free tier includes 6 months of data retention with upgrade paths to 2 years and unlimited. Heap's free tier also offers 6 months, but paid plan retention details and advanced features like session replay and heatmaps are locked behind opaque pricing tiers.

Where Heap Wins

Auto-Capture and Retroactive Analysis

Heap captures every click, pageview, form submission, and interaction automatically. You can define events and analyze behavior retroactively without having instrumented tracking in advance. This eliminates the risk of missing data because you forgot to track something.

AI-Powered Insights

Heap's Sense AI surfaces unexpected patterns, identifies friction points, and highlights opportunities in your data automatically. It proactively finds insights you might not have thought to look for.

Contentsquare Ecosystem
