7 Best Free Website Heatmap Tools in 2026: Complete Comparison

1. Microsoft Clarity — Best Overall Free Website Heatmap Tool

Microsoft Clarity is the only website heatmap tool that's genuinely, completely free with no session limits. There's no premium tier, no "upgrade for more sessions" nudge, and no artificial caps. You get unlimited heatmaps, unlimited session recordings, and built-in behavioral analytics for any number of websites. If you're looking for a website heatmap free of any cost or limits, Clarity is the clear winner.

Key Features

Limitations

Tip: Clarity's 30-day data retention can be a problem for trend analysis. Tools like ClarityInsights solve this by pulling and storing your Clarity data daily, giving you long-term behavioral data and automated weekly reports.

Verdict

For most websites, Clarity is the obvious first choice. Zero cost, no limits, and the behavioral signals (rage clicks, dead clicks) are features that competitors charge for.

2. Hotjar — Best Freemium UX Suite

Hotjar pioneered the heatmap-and-recording category and remains the most recognized name. Its free plan (Basic) gives you a taste of the platform, though the limits push you toward paid plans quickly.

Key Features

Free Plan Limitations

Verdict

Hotjar's free tier is best used as a trial. If you need surveys and feedback widgets alongside heatmaps, Hotjar's paid plans (starting ~$39/month) bundle them well. For heatmaps alone, Clarity offers more for free.

3. PostHog — Best for Developers

PostHog is an open-source product analytics platform that includes heatmaps and session recordings alongside event analytics, feature flags, A/B testing, and more. It's developer-centric, with a self-host option and a generous cloud free tier.

Key Features

Free Plan Limitations

Verdict

If your team already uses PostHog for product analytics (or wants a self-hosted option), adding heatmaps is a natural fit. But if you only need heatmaps and recordings, PostHog's complexity is overkill compared to Clarity.

4. Lucky Orange

Lucky Orange positions itself as an all-in-one conversion optimization suite for small businesses. Its free plan is modest but includes the core features.

Key Features

Free Plan Limitations

Verdict

The integrated live chat is a unique selling point. If you run a small business site and want chat + heatmaps in one tool, Lucky Orange is worth trying. The 500-session limit is tight for anything beyond a personal site.

5. Mouseflow

Mouseflow focuses on form analytics and funnel optimization alongside standard heatmaps and recordings. It's particularly strong at diagnosing why users abandon forms.

Key Features

Free Plan Limitations

Verdict

Mouseflow's form analytics on paid plans are best-in-class. The free tier is too limited for production use but works for evaluation. If forms are your primary conversion mechanism, Mouseflow's paid plans deserve consideration.

6. Smartlook

Smartlook (now part of Cisco) works on both websites and mobile apps, making it the strongest option if you need behavioral analytics across platforms.

Key Features

Free Plan Limitations

Verdict

If you have a mobile app alongside your website, Smartlook's cross-platform support is a real advantage. For web-only projects looking for a website heatmap free of session caps, Clarity's unlimited tier is more practical.

7. UXtweak

UXtweak combines heatmaps with usability testing tools like tree testing, card sorting, and first-click testing. It's designed for UX researchers who need more than just passive observation.

Key Features

Free Plan Limitations

Verdict

UXtweak is a niche tool for UX researchers who want testing methodologies beyond heatmaps. If you need tree tests or card sorts, it's unique. For pure heatmap use, other tools are more capable.

Are These Hotjar Alternatives?

Yes — every tool on this list works as a Hotjar alternative, but they each take a different approach. Hotjar popularized the heatmap-and-recording category, but its free tier (35 sessions/day) is no longer competitive in 2026. If you're searching for Hotjar alternatives that offer more generous free plans, here's how the main contenders stack up:

For most use cases, switching from Hotjar to Clarity gives you more data at zero cost. The main reason to stay with Hotjar is if you rely heavily on its survey and user interview features.

Can Google Analytics Replace a Heatmap Tool?

A common question is whether you need a dedicated website heatmap tool when you already have Google Analytics. The short answer: GA4 and heatmaps solve different problems, and you need both.

Google Analytics tells you what happens — which pages get traffic, where users drop off in a funnel, and what your conversion rates are. A website heatmap shows you why it happens — where users actually click, how far they scroll, and what elements they interact with (or try to interact with and fail).

GA4 does not include heatmap functionality. There is no "website heatmap Google Analytics" feature — Google discontinued its in-page analytics years ago and never replaced it. If you want click maps, scroll maps, or session recordings, you need a separate tool.

The good news: Microsoft Clarity integrates directly with Google Analytics. You can link your Clarity project to GA4 and see Clarity session recordings right from your GA4 reports. This gives you the best of both worlds — quantitative data from GA4, and qualitative visual data from a free heatmap tool — without replacing either one.

Our Recommendation

For most websites in 2026, the optimal free heatmap tool setup is:

  1. Start with Microsoft Clarity. It's free, unlimited, and gives you the core heatmap and recording functionality you need. The built-in behavioral signals (rage clicks, dead clicks, quick backs) are genuinely useful and exclusive to Clarity's free tier.
  2. Add a second tool only if you need a specific feature Clarity doesn't offer — surveys (Hotjar), mobile app tracking (Smartlook), self-hosting (PostHog), or form analytics (Mouseflow).
  3. Automate your analysis. The biggest challenge with any heatmap tool isn't collecting data — it's consistently reviewing it. Tools like ClarityInsights can pull your Clarity data automatically and send you weekly reports with AI-powered analysis, so behavioral issues don't go unnoticed.

Tip: Installing multiple heatmap tools simultaneously can slow down your page. If you're using Clarity as your primary tool, avoid adding more than one additional recording script. Check your page load times after installation.
