Best Heatmap Tools 2026: 6 Picks Compared (Hotjar, Microsoft Clarity, CrazyEgg + 3 More)

Heatmap tools answer one question: where do visitors look, click, and drop off on your pages? Six tools dominate the market in 2026, and the right pick depends on whether you need a free entry point, a paid CRO suite, a click-map specialist, a form-funnel detective, an enterprise platform, or a mobile-app SDK.

This comparison covers the six tools we use most often in client engagements: Microsoft Clarity, Hotjar, CrazyEgg, Mouseflow, FullStory, and Smartlook. Each entry follows the same format, best-for, what it gets right, what it gets wrong, pricing, so you can compare like-for-like.

1. Microsoft Clarity

Best for: Teams without budget who need a serious heatmap tool from day one.

What it gets right: Clarity is fully free, uncapped on sessions, and integrates cleanly with Google Analytics 4. The dead-click and rage-click detection is genuinely useful for diagnosing form friction. Privacy-compliant by default with built-in PII masking. Microsoft's scale means it absorbs traffic spikes without throttling.

What it gets wrong: No native A/B testing. Session recordings buffer can lag on high-traffic sites. The UI prioritises Microsoft conventions over CRO-team conventions, segmentation feels less intuitive than Hotjar.

Pricing: Free.

2. Hotjar

Best for: CRO teams under £200/month who want heatmaps, recordings, and on-page surveys in one suite.

What it gets right: The heatmap-plus-recording-plus-survey bundle is the strongest paid offering at its price point. Hotjar's segmentation is genuinely good, filter by traffic source, device, or custom event without writing code. The integration with Slack, HubSpot, and Optimizely is mature.

What it gets wrong: Session sampling on the Business plan caps visible sessions at 500 per day, which becomes a constraint above 100K monthly visitors. Heatmap rendering can take 24-48 hours to populate, which slows feedback loops on landing-page tests.

Pricing: £75/month (Plus), £200/month (Business), £400/month (Scale).

3. CrazyEgg

Best for: Agencies running structured A/B tests on landing pages where click distribution is the primary hypothesis.

What it gets right: CrazyEgg's confetti view, every click as a coloured dot, filterable by traffic source, remains the single best UI for diagnosing why a landing page underperforms. The built-in A/B test editor is lightweight but functional. Scroll-depth maps render faster than Hotjar's.

What it gets wrong: No session recordings on the Basic plan. Form analytics are a separate add-on. The platform's evolution has slowed, fewer feature releases than Hotjar or Clarity in the past 24 months.

Pricing: £29/month (Basic), £49/month (Standard), £99/month (Plus), £249/month (Pro).

4. Mouseflow

Best for: SaaS teams optimising signup and onboarding flows where funnel friction is the bottleneck.

What it gets right: Funnel-friction detection is class-leading, Mouseflow auto-flags rage-clicks, dead-clicks, and frustration-clicks across a defined funnel, then surfaces the highest-friction step. Form analytics show drop-off per field. The friction score lets you compare across funnels.

What it gets wrong: Heatmap rendering aggregates clicks differently than Hotjar, counts can look lower on the same traffic. Pricing scales aggressively past 100K sessions per month.

Pricing: £31/month (Starter), £109/month (Growth), £219/month (Business), Quote-only (Enterprise).

5. FullStory

Best for: Enterprise CRO teams running 30+ tests per quarter who need a digital-experience platform with heatmaps bundled in.

What it gets right: The session-replay engine is the most accurate in the market, sub-pixel-accurate mouse tracking, accurate scroll depth, and full DOM capture. Behavioural data feeds into a queryable warehouse you can SQL against. Anomaly detection auto-surfaces unusual user behaviour without you setting alerts.

What it gets wrong: Enterprise-only pricing puts it out of reach for sub-£10M revenue businesses. The product is over-engineered if you only need heatmaps. Implementation requires engineering time, not a paste-the-snippet install.

Pricing: Quote-only. Typical entry £25K/year, scaling to £150K+/year.

6. Smartlook

Best for: Mobile-app teams who need heatmaps inside iOS and Android apps, not just on web.

What it gets right: The mobile SDK is the best in class, native iOS and Android heatmaps, tap-density visualisation, and gesture replay. Web heatmaps are competent. Free plan available with 1,500 sessions per month, which is enough for initial validation.

What it gets wrong: Web heatmap features lag behind Hotjar and Mouseflow. The UI feels split between web and mobile workflows, neither is fully optimised. Customer-support latency has been reported as inconsistent in 2026 community threads.

Pricing: Free (1,500 sessions/mo), £45/month (Startup), £125/month (Business), Quote-only (Ultimate).

Quick-pick summary

How we use heatmap data in CRO engagements

At GoGoChimp, heatmaps are step 2 of a 4-step diagnostic: page-speed audit → heatmap analysis → A/B hypothesis generation → 99-Rule statistical test. Heatmaps alone don't lift conversion, they generate hypotheses. The lift comes from the test that follows.

The pattern we see most often: clients pick the wrong heatmap tool first (usually Hotjar by default), use it for 6 weeks, then realise they actually needed CrazyEgg's click-map specificity or Mouseflow's funnel-friction detection. Pick by use case, not by brand recall.

FAQ

Is Microsoft Clarity really free, or is there a paid tier?

Genuinely free. Microsoft monetises Clarity by feeding aggregated, anonymised behavioural data into Bing's ranking signals, they want the data more than they want subscription revenue. No paid tier exists in 2026.

Can heatmap tools replace A/B testing?

No. Heatmaps tell you what visitors do; A/B tests tell you what causes a lift. Use heatmaps to generate hypotheses, then test the hypothesis with statistical rigour (we use the 99 Rule, 99% statistical significance before declaring a winner).

Do heatmap tools slow down your site?

Marginally. Most modern heatmap scripts load asynchronously and add 30-80ms to page-load time. The exception is FullStory, which captures full DOM and can add 150-300ms, worth measuring on your Largest Contentful Paint before committing.

Which heatmap tool integrates best with Webflow?Hotjar and Microsoft Clarity both have native Webflow integrations. CrazyEgg requires a manual paste of the tracking script into the site-wide custom code. Mouseflow and Smartlook also paste manually.
