Free Heatmap Tools Guide: Session Replay, Privacy, Limits, UX Research, and Upgrade Signals (2026)
Compare free heatmap tools by session replay, click/scroll maps, privacy controls, sampling limits, UX research fit, product analytics, and upgrade signals using current market signals.
Heatmap and session-recording tools are useful only when their sampling, privacy, and retention model match the decisions you need to make. This guide was refreshed with vendor pricing-page research on May 24, 2026, and avoids brittle session-limit claims.
How we picked them
We focused on tools that offer a permanent free plan (not just a 14-day trial), capture at least clicks and scroll behavior, and integrate with the most common stack (Shopify, WordPress, Google Tag Manager). We checked 2026 plan pages directly for current limits.
Free heatmap tools to compare in 2026
1. Microsoft Clarity
Clarity is the easiest free starting point for click maps, scroll maps, recordings, rage-click and dead-click insights. The trade-off: data lives inside Microsoft’s analytics platform, so privacy review is required for serious rollouts.
2. Hotjar
Hotjar is a polished UX-research workflow with heatmaps, recordings, feedback, and surveys. Verify current free and paid capture limits before using it on a full site.
3. Smartlook
Smartlook is useful when you need web and mobile session behavior with funnels and recordings. Verify current capture, retention, and mobile SDK limits.
4. Mouseflow
Mouseflow combines heatmaps, funnels, form analytics, and recordings. Check current free and paid limits for recordings, retention, and domains.
5. Lucky Orange
Lucky Orange is a trial or paid path for heatmaps, recordings, chat, and conversion tools. Include it when you want an all-in-one CRO workflow.
6. Crazy Egg
Crazy Egg is worth comparing if you want a polished, focused-on-CRO interface with heatmaps and testing-oriented workflows.
7. FullStory
FullStory is stronger as session replay and product analytics than as a pure heatmap tool. Verify current session, retention, and workspace gates.
8. PostHog
PostHog is open-source product analytics with heatmaps and session recordings available. It fits product and engineering teams that want event analytics, SQL-style access, and self-hosting as an option.
9. UXtweak
UXtweak fits teams that want to combine heatmaps with task-based UX research. Verify current study, participant, and analytics limits.
10. Inspectlet
Inspectlet is a lean heatmap and session-recording option. Verify current capture, retention, and plan availability.

How to choose
Three questions to settle the call:
- How much traffic do you have? Higher-traffic sites should verify session, event, retention, and sampling limits because many free plans work best for early-stage testing.
- Do you need session recordings or just heatmaps? Heatmaps alone come standard everywhere. Full recordings push you toward Clarity, Smartlook, or FullStory.
- What is your privacy posture? If you process EU traffic and have strict consent requirements, prefer tools with built-in masking and EU data residency (Smartlook, Mouseflow EU, PostHog self-hosted).
Where heatmaps fit in your conversion stack
Heatmaps tell you which sections people read and which they ignore. Pair them with your email and onsite data to find leverage. For example: a heatmap shows that visitors never scroll to the cart upsell on your product page, while your Brevo data shows your abandoned cart email is your top revenue trigger. The fix is probably moving the upsell above the fold and refining the cart-recovery email copy. If your Shopify store syncs into Brevo through Tajo, you can match heatmap insights to the customer segments that actually convert and prioritize fixes that move revenue, not vanity metrics.
FAQ
Is Microsoft Clarity really free? Yes. Microsoft offers Clarity free as part of its broader advertising and analytics ecosystem. There is no paid tier and no session cap. Data is hosted by Microsoft and is GDPR compliant when configured correctly.
Can I run two heatmap tools at once? You can, but it adds page weight and creates duplicate consent prompts. Most teams pick one and stick with it for at least a quarter to gather meaningful data.
Will heatmaps work on a Shopify store? Yes. Clarity, Hotjar, Smartlook, and Mouseflow all install via a single script tag or a Shopify app and start capturing within minutes.
Do heatmaps respect cookie consent? Tools like Hotjar, Smartlook, and Mouseflow include consent-mode integrations. Clarity respects DNT and offers GDPR cookie consent settings, but configuration is on you.
