Free Heatmap Tools for Solo Founders

You shipped. Users are coming. But you have no idea where they're clicking, scrolling, or bouncing.

This is the brutal truth: without heatmaps, you're flying blind. You're guessing at what breaks the user experience. You're optimizing for feelings instead of data.

Heatmaps show you exactly where users click, how far they scroll, and where they rage-quit. They're the difference between a product that converts and one that hemorrhages users.

But hiring an agency to analyze user behavior? That's $5K-$15K you don't have. And building custom analytics? That's time you should spend shipping.

The good news: the best heatmap tools are now free. Not "free trial." Free forever. Microsoft Clarity, Hotjar, Lucky Orange, and others will show you everything you need to know about how users interact with your site—without touching your bootstrap budget.

This guide walks you through the free heatmap options, shows you how to set each one up, and helps you pick the one that fits your stack and workflow.

Prerequisites: What You Need Before You Start

Before you install a heatmap tool, make sure you have these basics in place:

Access to your website code or admin panel. You need to either add a tracking script to your site's header or install a WordPress plugin. If you're on Webflow, Framer, or Next.js, you'll need the ability to add custom code or use a plugin system.

Google Analytics 4 or similar analytics setup. Heatmaps work best when paired with traffic data. You should already know roughly how many visitors you get per day. If not, set up your free SEO tool stack first so you have baseline metrics.

A modern browser. Chrome, Firefox, Safari, or Edge. The heatmap tools work in all of them, but Chrome's developer tools will help you debug if something breaks.

Realistic expectations about sample size. Heatmaps need traffic to be useful. If you get 10 visitors a day, you'll have spotty data. If you get 100+ per day, you'll have reliable heatmaps within a week. Plan accordingly.

Privacy policy updated. Most heatmap tools record session replays and user behavior. You legally need to disclose this in your privacy policy and, in some regions, get user consent. This takes 10 minutes to add.

Once you have these in place, you're ready to pick a heatmap tool and start seeing how users actually interact with your site.

The Heatmap Landscape: What You're Actually Comparing

Before we dive into specific tools, understand what heatmaps actually measure. There are three types:

Click heatmaps. Shows every click on your page. Red zones = high-click areas. Blue zones = ignored areas. Instantly reveals whether users are clicking buttons, links, or random text.

Scroll maps. Shows how far down the page users scroll before leaving. Red at the top means people scroll past it. Red at the bottom means they're reading deep. This kills the "above the fold" myth and shows you where attention actually lives.

Session recordings. Video playback of real user sessions. Watch a user navigate your site, see where they hesitate, click the wrong button, or abandon the flow. This is the "why" behind the heatmap data.

Not all free heatmap tools include all three. Some give you clicks and scrolls but limit session recordings. Others cap the number of recordings you can view per month. This is where your choice matters.

The 15 best heatmap software tools compared in 2026 breaks down the feature differences clearly. The 12 best heatmap tools in 2026 also compares pricing tiers and what you actually get in each free plan.

Now let's look at the specific free options you should consider.

Option 1: Microsoft Clarity—The Truly Free Forever Choice

Microsoft Clarity is the rare exception: a heatmap tool with no catch. Unlimited heatmaps. Unlimited session recordings. Unlimited users. Free forever.

This sounds too good to be true. It's not. Microsoft built Clarity to compete with Hotjar and Crazy Egg, and they decided to give away the core product. Why? They're Microsoft. They can afford it. And they want your data to improve their AI models. Fair trade.

What Clarity gives you:

• Unlimited click heatmaps
• Unlimited scroll maps
• Unlimited session recordings (up to 30 days of retention)
• Rage-click detection (automatically flags frustrated clicks)
• Dead-click detection (clicks on non-clickable elements)
• Basic filtering by device, page, and user properties
• Integration with Google Analytics 4

What Clarity doesn't give you:

• Form analytics (which fields users abandon)
• Conversion funnels
• A/B testing tools
• Advanced segmentation
• Custom event tracking beyond what GA4 provides

For a solo founder, this limitation doesn't matter. You don't need form analytics to see that users are abandoning your signup page. You'll see it in the session recordings.

How to set up Microsoft Clarity:

1. Go to clarity.microsoft.com and sign in with your Microsoft account (or create one—it's free).
2. Click "Create a new project" and enter your website URL.
3. Clarity will generate a tracking code. Copy it.
4. Add the code to your website's <head> tag. If you're on WordPress, use a plugin like "Insert Headers and Footers." If you're on Webflow, use the custom code embed. If you're on Next.js, add it to your _document.js file.
5. Wait 5-10 minutes for Clarity to start collecting data.
6. Go back to your Clarity dashboard and refresh. You should see your first sessions within minutes.

Pro tip: Clarity integrates directly with Google Analytics 4. If you're already tracking GA4 events, Clarity will automatically sync those dimensions. This means you can filter heatmaps by "users who converted" or "users from paid ads." Powerful.

Option 2: Hotjar—The Industry Standard with a Real Free Tier

Hotjar is the heatmap tool everyone knows. It's been around since 2014. It has a massive free plan. And it's the closest thing to an industry standard in the heatmap space.

Why mention Hotjar when Clarity is free forever? Because Hotjar's free tier is genuinely useful, and some founders prefer it for specific reasons:

Hotjar's free plan includes:

• 3 heatmaps per site
• 100 session recordings per month
• Scroll maps and click maps
• Basic surveys and feedback polls
• Integration with Google Analytics
• Mobile heatmaps

Hotjar's limitations on the free plan:

• Only 3 active heatmaps (you can swap them, but not run them simultaneously)
• 100 session recordings per month (roughly 3-4 per day)
• No form analytics
• No conversion funnels
• No advanced filtering or segmentation
• No rage-click or dead-click detection

For a solo founder with moderate traffic (100-500 visitors per day), the 100 recordings per month is tight. You're sampling user behavior, not seeing the full picture.

When to choose Hotjar over Clarity:

• You want built-in surveys and feedback tools (Clarity doesn't have these)
• You prefer a more polished UI (subjective, but Hotjar's interface is more intuitive for non-technical founders)
• You need the credibility of the industry standard (Hotjar is more recognizable in investor conversations)
• You want mobile heatmaps specifically (Clarity has them, but Hotjar's mobile heatmaps are slightly better)

How to set up Hotjar:

1. Go to hotjar.com and sign up for the free plan.
2. Add your website URL and verify ownership (Hotjar will ask you to add a small HTML snippet or a DNS record).
3. Once verified, Hotjar generates a tracking code. Copy it.
4. Add the code to your website's <head> tag using the same method as Clarity (WordPress plugin, Webflow embed, Next.js _document.js, etc.).
5. Wait 5-10 minutes. Check your Hotjar dashboard for incoming sessions.
6. Create your first heatmap by selecting a page and choosing "click map" or "scroll map."
7. Let it collect data for 24 hours before drawing conclusions.

Pro tip: Hotjar's surveys are underrated. You get 1 survey per site on the free plan. Use it strategically. Instead of guessing why users bounce, ask them directly: "What would make you stay?" Put the survey on your exit page. You'll get 5-10 responses per week from real users. That's gold.

The official Hotjar site has detailed documentation on every feature. Start there if you get stuck.

Option 3: Lucky Orange—The Balanced Middle Ground

Lucky Orange sits between Clarity and Hotjar. It's not as famous as Hotjar, but it's more feature-rich than Clarity's free tier. And it's been around since 2010, so it's battle-tested.

Lucky Orange's free plan includes:

• 1 unlimited heatmap
• Unlimited session recordings
• Scroll maps and click maps
• Form analytics (which fields users abandon)
• Basic conversion funnels
• Mobile heatmaps
• 30 days of data retention

Lucky Orange's limitations on the free plan:

• Only 1 heatmap (you can only track one page at a time)
• Limited to 1,000 recorded sessions per month (higher than Hotjar, but still a limit)
• No A/B testing
• No advanced segmentation
• No custom event tracking
• No rage-click or dead-click detection

When to choose Lucky Orange over Clarity or Hotjar:

• You need form analytics (to see which fields users abandon in your signup flow)
• You want conversion funnels out of the box (to track where users drop off in a multi-step process)
• You prefer a lighter-weight tool that doesn't feel over-engineered
• You're willing to trade "unlimited heatmaps" for "better form insights"

Form analytics is the differentiator here. If your product has a complex signup flow or a multi-step checkout, Lucky Orange's form analytics will show you exactly where users bail. That's worth the trade-off of having only 1 active heatmap.

How to set up Lucky Orange:

1. Go to luckyorange.com and sign up for the free plan.
2. Add your website URL.
3. Lucky Orange generates a tracking code. Copy it.
4. Add the code to your website's <head> tag (same process as Clarity and Hotjar).
5. Within 5-10 minutes, you'll see your first sessions in the dashboard.
6. Create your first heatmap by selecting a page and the heatmap type.
7. Go to "Forms" to see which fields are being abandoned.

Pro tip: Lucky Orange's form analytics are real-time. As users fill out your form, you can see which fields they're struggling with, how long they spend on each field, and where they abandon. This is invaluable for optimizing signup conversion rates. If you see users spending 30 seconds on your "Company" field and then leaving, that field might be confusing or unnecessary.

The good free heatmap tools review compares Lucky Orange's free tier directly with other options and highlights its form analytics strength.

Option 4: Smartlook—The Lightweight Alternative

Smartlook is less famous than Hotjar or Clarity, but it's a solid free option if you want session recordings and heatmaps without bloat.

Smartlook's free plan includes:

• Unlimited heatmaps
• Unlimited session recordings
• Scroll maps and click maps
• Mobile heatmaps
• Basic filtering
• 30 days of data retention

Smartlook's limitations on the free plan:

• No form analytics
• No conversion funnels
• No surveys or feedback tools
• No rage-click or dead-click detection
• Limited to 500 recorded sessions per month

When to choose Smartlook:

• You want unlimited heatmaps and unlimited recordings (within the 500/month session limit)
• You prefer a minimal, lightweight tool
• You don't need form analytics or surveys
• You're building on a tech stack where Smartlook integrates better (it has good SDKs for React and Vue)

Smartlook is honestly a solid alternative to Clarity if you prefer a different UI or if you need better developer documentation for custom event tracking.

How to set up Smartlook:

1. Go to smartlook.com and create a free account.
2. Add your website URL.
3. Smartlook generates a tracking code. Copy it.
4. Add the code to your website's <head> tag.
5. Wait for data to start flowing (5-10 minutes).
6. Create your first heatmap from the dashboard.

Pro tip: Smartlook has excellent documentation for developers. If you're on React or Vue and want to track custom events (like "user clicked the pricing button"), Smartlook's SDK makes it easy. This is useful if you want to correlate user behavior with specific product interactions.

The G2 list of best free heatmap tools includes Smartlook with user reviews and comparisons to other free options.

Option 5: Plerdy—The Budget-Conscious Pick

Plerdy is a Ukrainian heatmap tool that's gained traction with bootstrappers because it's genuinely free and doesn't nag you to upgrade.

Plerdy's free plan includes:

• Unlimited heatmaps
• Unlimited session recordings
• Scroll maps, click maps, and move maps (heatmaps of mouse movement)
• Form analytics
• 30 days of data retention
• Mobile heatmaps

Plerdy's limitations on the free plan:

• Limited to 500 recorded sessions per month
• No conversion funnels
• No A/B testing
• No surveys
• UI is less polished than Hotjar or Clarity

When to choose Plerdy:

• You want form analytics plus unlimited heatmaps (like Lucky Orange, but free)
• You're okay with a slightly less polished UI
• You want to see mouse movement heatmaps (unique to Plerdy among free tools)
• You're bootstrapped and every dollar counts

Plerdy's move maps are interesting. They show where users move their mouse, which can reveal confusion or hesitation before a click. It's a subtle signal that most heatmap tools ignore.

How to set up Plerdy:

1. Go to plerdy.com and sign up for the free plan.
2. Add your website URL.
3. Plerdy generates a tracking code. Copy it.
4. Add the code to your website's <head> tag.
5. Wait 5-10 minutes for data to start flowing.
6. Create your first heatmap from the dashboard.

Pro tip: Plerdy's free plan doesn't have conversion funnels, but you can build a manual funnel by looking at session recordings. Watch 10 users go through your signup flow and note where they drop off. It's not automated, but it works.

The best heatmap tools overview mentions Plerdy as a strong free option for startups.

How to Choose: The Decision Framework

You now have five solid free heatmap options. How do you pick?

Use this decision tree:

Do you need form analytics (to see which fields users abandon)?

• Yes → Choose Lucky Orange or Plerdy
• No → Continue to next question

Do you want unlimited heatmaps and recordings with no monthly limits?

• Yes → Choose Microsoft Clarity
• No → Continue to next question

Do you want the industry standard with built-in surveys?

• Yes → Choose Hotjar
• No → Choose Smartlook or Plerdy

That's it. This framework will get you to the right tool for your stack.

But here's the real secret: you don't have to pick just one. Install Clarity (it's free and unlimited). Then add Hotjar or Lucky Orange if you need specific features. The tracking scripts don't conflict. You'll get redundant data, but that's actually useful for validation.

Step-by-Step: Installing Your First Heatmap (Using Clarity as the Example)

Let's walk through a real installation. We'll use Microsoft Clarity because it's the simplest.

Step 1: Create a Clarity account

Go to clarity.microsoft.com. Click "Sign in" and use your Microsoft account (or create one). If you don't have a Microsoft account, click "Create one" and follow the prompts. This takes 2 minutes.

Step 2: Create a new project

Once you're logged in, click "Create a new project." Enter your website URL (e.g., https://example.com). Click "Create project."

Clarity will ask you to verify ownership of the site. You have two options: add an HTML meta tag to your site's <head>, or add a DNS record. The HTML tag is faster.

Step 3: Get your tracking code

Clarity will generate a tracking code that looks like this:

<script async src="https://www.clarity.ms/tag/xxxxxxxx?ref=beanstalk"></script>

Copy this entire code block.

Step 4: Add the code to your website

Where you add this depends on your platform:

If you're on WordPress: Install the plugin "Insert Headers and Footers" (it's free). Go to Settings → Insert Headers and Footers. Paste the Clarity code into the "Headers" section. Click Save.

If you're on Webflow: Go to your project settings. Click "Custom code." Paste the Clarity code into the "Head code" section. Click Save and publish.

If you're on Next.js: Open your _document.js file (or create one in the pages directory). Add the Clarity code inside the <Head> component. Redeploy.

If you're on a custom HTML site: Open your site's main HTML file and paste the code into the <head> section, right before the closing </head> tag. Save and upload.

If you're on Shopify: Go to Settings → Online Store → Preferences. Scroll to "Additional scripts." Paste the Clarity code. Click Save.

Step 5: Verify installation

Go back to your Clarity dashboard. Click "Verify installation." Clarity will check if the code is on your site. If it finds it, you'll see a green checkmark. If not, wait 5 minutes and try again (it takes time to propagate).

Step 6: Wait for data

Once verified, Clarity starts collecting data immediately. Go back to your site and navigate around. Refresh the Clarity dashboard after a few minutes. You should see your own session recorded.

Step 7: Create your first heatmap

In the Clarity dashboard, click "Heatmaps." Select the page you want to analyze. Choose "Click heatmap" or "Scroll map." Click "Create heatmap."

Clarity will start collecting heatmap data. Wait 24 hours for meaningful data (you need at least 50-100 users to see patterns).

Step 8: Interpret your heatmap

Once you have data, look for:

• Red zones on buttons you want users to click. Good. Users are engaging.
• Red zones on text or images you don't want users to click. Bad. You might have misleading UI.
• Scroll maps that drop off before your CTA. Bad. Move your CTA higher or make it more compelling.
• Scroll maps that go all the way to the bottom. Good. Users are reading your content.

Take screenshots of your heatmaps. Share them with your co-founder or your team. Discuss what you're seeing. Then make one change based on what you learned. Wait a week. Check your heatmap again. Repeat.

Integrating Heatmaps with Your Broader SEO Stack

Heatmaps are powerful, but they're just one piece of your SEO and conversion optimization puzzle. They work best when paired with other tools.

You should already have Google Search Console set up to track which keywords drive traffic. You should be running Lighthouse audits to check your site speed. You should have PageSpeed Insights configured to monitor Core Web Vitals.

Now add heatmaps to this stack:

1. See which keywords drive traffic (GSC) → See where those users click (Heatmaps) → Optimize the user flow (Make changes, re-test)
2. Track site speed (Lighthouse, PageSpeed Insights) → Watch users interact with slow pages (Heatmaps) → Identify if speed is causing bounces (Session recordings)
3. Monitor SEO metrics (GA4, rank tracking) → See what pages convert (Heatmaps + GA4 integration) → Double down on high-converting content

This is the founder's SEO workflow. You're not guessing. You're watching real users and iterating based on what you see.

If you haven't set up your broader SEO tool stack yet, start with the free SEO tool stack every founder should set up today. It covers GSC, GA4, Lighthouse, and keyword research. Then come back to heatmaps.

Once you have heatmaps running, you can also set up rank tracking on a bootstrapper's budget to track which keywords are moving. Pair that with heatmaps and you'll see the full picture: which keywords drive traffic, which pages those users land on, and where they convert or bounce.

Common Mistakes and How to Avoid Them

Founders make predictable mistakes with heatmaps. Here's how to avoid them:

Mistake 1: Not waiting for enough data before drawing conclusions.

You install Clarity, get 5 session recordings, and optimize based on what you see. Don't do this. Wait for at least 50-100 sessions before making changes. Heatmaps show you patterns, not individual outliers.

Mistake 2: Optimizing for the wrong metric.

You see that users click a lot on your "Pricing" button. You make it bigger and more prominent. But users clicking "Pricing" doesn't mean they're converting. Watch the session recordings. Do they click Pricing, look at your prices, and leave? Then your pricing is the problem, not the button visibility.

Mistake 3: Installing a heatmap tool and forgetting about it.

Heatmap tools only work if you actually look at the data. Set a recurring reminder: every Monday, spend 15 minutes reviewing your heatmaps. Look for new patterns. Watch 2-3 session recordings. Make one small change. That's it.

Mistake 4: Not combining heatmaps with qualitative feedback.

Heatmaps show you what users do. Surveys and user interviews show you why. Use both. Install a Hotjar survey on your exit page: "What would make you stay?" Get 5-10 responses. Combine that with your heatmap data. Now you have context.

Mistake 5: Tracking too many pages at once.

If you're on Hotjar's free plan, you get 3 heatmaps. Don't spread them across 10 pages. Pick your 3 most important pages: your homepage, your main product page, and your pricing page. Track those. Once you've optimized them, move to the next 3.

Pro Tips for Getting the Most Out of Free Heatmaps

Tip 1: Combine heatmaps with Google Analytics events.

If you're using Clarity, connect it to GA4. Then you can filter heatmaps by user properties. Show me heatmaps for only users who came from paid ads. Show me heatmaps for only users who spent more than 30 seconds on the page. This is powerful segmentation without paying for it.

Tip 2: Use session recordings to debug UX issues.

You notice that users are clicking on something that's not clickable (a dead click). Instead of guessing why, watch a session recording. Maybe the styling makes it look like a button. Maybe it's a confusing interaction pattern. The video will show you.

Tip 3: Track the same page across different traffic sources.

Use Clarity's filters to compare heatmaps for users from organic search vs. paid ads vs. direct traffic. Do organic users scroll further than paid users? Do they click different elements? This tells you something about user intent and content relevance.

Tip 4: Export heatmap images for your roadmap.

Take screenshots of your heatmaps before and after you make changes. Put them in a Google Doc. This becomes your UX optimization roadmap. You can show investors or your team: "Here's what we found. Here's what we changed. Here's the result."

Tip 5: Set up alerts for rage clicks.

If you're using Clarity, it automatically detects "rage clicks" (when a user clicks the same non-clickable element multiple times in frustration). These are goldmines. If users are rage-clicking something, it's broken or confusing. Fix it immediately.

Building Your Heatmap Workflow

Don't just install a heatmap tool and hope it magically improves your site. Build a repeatable workflow:

Week 1: Install and collect baseline data.

Pick your heatmap tool (use the decision framework above). Install it. Let it collect data for a full week. Don't make any changes yet.

Week 2: Analyze and identify patterns.

Spend 1-2 hours reviewing your heatmaps and session recordings. Look for:

• Pages with high bounce rates (are users leaving immediately?)
• Elements with lots of clicks (are they supposed to be clickable?)
• Pages where users don't scroll (is your content above the fold compelling?)
• Rage clicks or dead clicks (are you confusing users?)

Write down your top 3 observations.

Week 3: Make one change per observation.

Don't change everything at once. Pick one observation and make one small change. If users aren't scrolling past the fold, move your CTA higher. If users are rage-clicking a button, make sure it's actually clickable. If users are bouncing on a landing page, rewrite the headline.

Week 4: Measure the impact.

Let your change run for a week. Check your heatmap again. Did scroll depth improve? Did rage clicks decrease? Did engagement increase? Compare before and after.

If the change helped, keep it and move to the next observation. If it didn't help, revert it and try something else.

Repeat every month.

This is the founder's conversion optimization loop. It's not flashy. It's not sexy. But it works.

Heatmaps and SEO: Why This Matters for Organic Growth

You might be wondering: "How does user behavior on my site affect my SEO rankings?"

Direct answer: it doesn't. Google doesn't use heatmap data to rank your site.

But here's the indirect effect: heatmaps help you build a better user experience, which increases time on site, reduces bounce rate, and improves conversion rate. These are signals that Google notices. A site where users spend 3 minutes and convert is more valuable than a site where users bounce after 10 seconds.

Plus, if you're optimizing based on heatmap data, you're probably also improving your content quality, page speed, and mobile experience. All of these are ranking factors.

So the workflow is: use heatmaps to improve UX → users spend more time on your site → bounce rate decreases → conversion rate increases → Google notices the engagement signals → rankings improve.

This is why heatmaps belong in your SEO toolkit alongside technical audits, rank tracking, and site speed monitoring.

You can also use heatmap insights to inform your content strategy. If you see that users are scrolling all the way to the bottom of your "How to X" guide, that tells you the content is engaging. Double down on that format. If users are bouncing halfway through, the content isn't delivering. Rewrite it.

Comparing Heatmap Tools Head-to-Head

Let's put the five tools side-by-side so you can see the differences clearly:

Based on this table:

• Best overall: Clarity (unlimited everything, free forever)
• Best for surveys: Hotjar (built-in feedback tools)
• Best for forms: Lucky Orange or Plerdy (form analytics)
• Best for developers: Smartlook (excellent SDKs)
• Best for budget: Any of them (all genuinely free)

Wrapping Up: Your Next Steps

You now have everything you need to pick and install a free heatmap tool. Here's what to do right now:

1. Pick a tool using the decision framework above. If you're unsure, start with Microsoft Clarity. It's the safest choice.

2. Install it using the step-by-step guide above. This takes 10 minutes.

3. Let it collect data for 24-48 hours. You need at least 20-30 sessions to see patterns.

4. Review your first heatmap. Watch 3-5 session recordings. Write down what you notice.

5. Make one small change based on what you learned. Don't overthink it.

6. Measure the impact after a week.

7. Repeat monthly.

This is the founder's conversion optimization workflow. It's not fancy. It doesn't require an agency. But it works.

If you want to go deeper, check out the SEO bootcamp for busy founders, which includes a full 14-day playbook for improving your site's organic visibility. Or read from busy to cited: a founder's roadmap from day 0 to day 100, which shows you how to build a complete SEO foundation in 100 days.

But start with heatmaps. They're free. They're powerful. And they show you exactly what your users are doing. That's the foundation of everything else.

Now go install one. Your users are waiting to tell you what's broken.
