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.
