CRO isn’t one tool. It’s a stack. Here’s what each category does and which tools are actually worth your budget.

CRO Tools overview

CRO tools fall into four categories, and confusing them is how most teams waste money. Analysis tools tell you what’s wrong. Behavior tools show you how visitors interact. Testing tools validate which fix works better. Builder tools help you implement changes without engineering.

Most teams only need one tool from each category. Start with analysis (find the problems) and behavior (understand the problems), then add testing once you have enough traffic to run statistically significant experiments.

Here’s the stack, organized by category. We’re honest about where roast.page fits — we’re in the analysis category. We don’t do heatmaps, A/B testing, or page building. Different tools for different jobs.

1.

roast.page

By us

AI-powered page analysis that evaluates conversion potential across 8 dimensions. Identifies specific issues with your headline, CTAs, trust signals, and visual hierarchy. The starting point: find out what’s wrong before you start fixing.

Best for: Identifying conversion issues before investing in testing or redesign

Free (3 analyses) · Packs from $40

2.

Hotjar

The most popular behavior analytics tool. Heatmaps show where visitors click, move, and scroll. Session recordings show individual visitor journeys. Surveys let you ask visitors directly. The free tier is generous enough for most small teams.

Best for: Understanding how visitors actually interact with your page

Free (35 daily sessions) · From $32/mo

3.

Microsoft Clarity

Completely free heatmaps and session recordings, backed by Microsoft. No traffic limits, no sampling. Integrates with Google Analytics. The data quality matches Hotjar for most use cases. Hard to justify paying for heatmaps when Clarity exists.

Best for: Free heatmaps and session recordings with no limits

Free, forever

4.

VWO

Full experimentation platform: A/B testing, multivariate testing, split URL testing, personalization. The visual editor lets non-developers create test variants. Server-side testing for SPAs. The pricing jumps fast, but the testing capabilities are enterprise-grade.

Best for: Teams ready for serious A/B testing programs

Free (limited) · From $199/mo

5.

Optimizely

Enterprise experimentation platform. Feature flags, A/B testing, personalization, content management. Overkill for most startups but unmatched for organizations running dozens of concurrent experiments across multiple teams.

Best for: Enterprise teams running large-scale experimentation programs

Custom pricing (typically $50K+/year)

6.

Crazy Egg

Heatmaps, scroll maps, confetti reports, session recordings, and a basic A/B testing feature. The A/B testing integration with behavior data is unique — you can test based on what heatmaps reveal. Less feature-rich than VWO for testing, but simpler.

Best for: Teams who want heatmaps and basic A/B testing in one tool

From $49/mo (no free tier)

7.

Unbounce

Landing page builder with Smart Traffic — AI that automatically routes visitors to the page variant most likely to convert for them. Not traditional A/B testing; more like AI-powered personalization. Only useful if you build pages on Unbounce.

Best for: Building and optimizing landing pages in one platform

From $74/mo

8.

Lucky Orange

Combines heatmaps, recordings, form analytics, and live chat. The form analytics feature is standout — shows exactly where visitors abandon forms, which fields cause hesitation, and which error messages frustrate users.

Best for: Diagnosing form abandonment and conversion friction

Free (limited) · From $32/mo

9.

AB Tasty

Experimentation and personalization platform positioned between VWO and Optimizely. Feature flags, A/B testing, personalization, and widget deployment. Good middle ground for mid-market companies that need more than basic A/B testing but less than Optimizely’s full stack.

Best for: Mid-market teams who’ve outgrown basic A/B testing

How to choose

Start with diagnosis, not testing

Running A/B tests without knowing what’s wrong is like prescribing medicine without a diagnosis. Start with analysis (find issues) and behavior data (understand context), then test fixes.

Match tool to traffic volume

A/B testing requires statistical significance. Below 1,000 visitors/month per variant, tests take too long to be useful. Focus on analysis and best practices first. Test when you have the traffic.

Free tiers are surprisingly good

Microsoft Clarity (free, unlimited) and roast.page (3 free analyses) give you behavior data and conversion analysis without spending anything. Start free, upgrade when you hit limits.

Don’t buy the all-in-one promise

Tools that claim to do everything (heatmaps + testing + personalization + analytics) usually do each thing at 60% quality. Purpose-built tools in each category tend to be better.

Common questions

What CRO tools does a startup actually need?

Start with roast.page or similar for analysis, Microsoft Clarity for behavior data, and Google Analytics for baseline metrics. That’s it until you have enough traffic for A/B testing (usually 5,000+ visitors/month).

Is A/B testing worth it for small sites?

Not until you have at least 1,000 conversions per month. Below that threshold, tests don’t reach statistical significance fast enough to be useful. Focus on best practices and expert analysis instead.

Hotjar vs. Microsoft Clarity — which one?

Clarity is free with no limits. Hotjar’s paid plans add surveys, feedback widgets, and better UX. If you only need heatmaps and recordings, Clarity. If you want built-in user feedback tools, Hotjar.

How do I know if my CRO efforts are working?

Track conversion rate over time in Google Analytics. Compare before and after specific changes. Set up goal tracking for your primary conversion action. Don’t rely on tool scores alone — revenue is the real metric.

What order should I build my CRO stack?

Month 1: analysis tool + free behavior analytics. Month 3: form analytics if relevant. Month 6+: A/B testing if traffic supports it. Year 2: personalization if you’ve validated through testing.
