Crazy Egg, Croct, and Omniconvert Explore compared: heatmap diagnostics and React-only developer testing versus Shopify-native eCommerce CRO measured in revenue per visitor.
Answer Capsule

Crazy Egg is a heatmap and session recording tool with basic two-variant A/B testing on any webpage. Croct is a developer-first testing and personalization platform for React and Next.js applications. Omniconvert Explore is the Shopify-native eCommerce CRO platform: it runs A/B, multivariate, and checkout experiments no-code on product pages, cart, and checkout, measured in revenue per visitor.

Key Takeaways
  • Crazy Egg is a heatmap and session recording tool with basic two-variant A/B testing, and holds a 4.2 out of 5 G2 rating. [G2, 2026]
  • Croct is a developer-first A/B testing and personalization platform for React and Next.js applications, and holds a 4.7 out of 5 G2 rating. [G2, 2026]
  • The two tools solve opposite problems for different teams, but leave the same gap: the standard Shopify store's product, cart, and checkout path.
  • Neither runs multivariate experiments on Shopify Liquid themes or measures results in revenue per visitor, the metric that actually moves store revenue.
  • Omniconvert Explore is Shopify-native and no-code first, running A/B, multivariate, and server-side experiments on product, cart, and checkout, measured in revenue per visitor: pick it for a standard Shopify store.

Teams comparing Crazy Egg vs Croct are usually stuck between two very different testing ceilings. Crazy Egg gives them cheap heatmaps and a basic two-variant test that never reaches Shopify checkout. Croct gives them developer-first component testing that only runs on React or Next.js code. Neither is built for a standard Shopify store whose marketing team needs controlled, revenue-focused experiments on product pages, cart, and checkout, which is where Omniconvert Explore fits.

What is Crazy Egg, and what is it actually good at?

Crazy Egg is a heatmap and session recording tool with lightweight A/B testing. It shows where users click, scroll, and engage on a page, and includes a basic two-variant test in every plan at an entry price around $49 per month. It is aimed at non-technical marketers on any website. [Crazy Egg, 2026]

Crazy Egg is a behavior analytics tool first and a testing tool second. It holds a 4.2 out of 5 rating on G2 across 144 reviews. [G2, 2026] Its strength is making click, scroll, and engagement data easy to see for teams without an analyst, at a low entry price.

The A/B testing it includes is deliberately simple: single-page, two-variant tests. That suits a marketer who wants to compare one headline against another, not a program of experiments across a store funnel.

Heatmaps defined

A heatmap aggregates where visitors click, move, and scroll on a page into a visual overlay, so a team can see attention and friction at a glance. Crazy Egg does this well and pairs it with recordings. It is a diagnosis layer, distinct from running a controlled revenue experiment on product, cart, and checkout pages.

Where Crazy Egg is genuinely strong

  • Heatmaps and scroll maps: a clear, visual read on where clicks and attention land.
  • Session recordings: watch real sessions to see where users hesitate on a page.
  • Low entry price: accessible plans that small businesses can start on quickly.
  • Basic A/B testing included: a simple two-variant test in every plan for light experiments.

Where Crazy Egg hits its ceiling for an eCommerce store

  • Testing is basic: no multivariate testing, no server-side testing, and no advanced audience targeting.
  • No checkout experiments: it cannot run tests on the Shopify product, cart, or checkout flow.
  • Analytics first: teams serious about CRO outgrow its experiment features quickly.
  • Generic conversion focus: no concept of revenue per visitor as a tested outcome.

What is Croct, and what is it actually good at?

Croct is a developer-first A/B testing and personalization platform built specifically for React and Next.js applications. It integrates at the component level through a code-first API and is popular with headless eCommerce engineering teams. Experiments, personalization, and feature flags are all configured in code by developers. [Croct, 2026]

Croct is an engineering tool, not a marketing tool. It holds a 4.7 out of 5 rating on G2 across 47 reviews. [G2, 2026] Its strength is that it feels native to a modern React or Next.js codebase: engineers wire experiments into components the same way they ship features, with server-side execution and a free tier for smaller usage.

What Croct is not is a tool a Shopify marketing team can use on its own. Every test lives in code, there is no visual editor, and standard Shopify Liquid themes are out of scope unless the store replatforms to a headless React front end.

Developer-first testing defined

Developer-first testing means every experiment, variant, and audience rule is defined in the application codebase and shipped through the normal deploy pipeline. Croct does this well for React and Next.js teams. It is a code-owned execution layer, distinct from a marketer-run experimentation platform on Shopify's product, cart, and checkout pages.

Where Croct is genuinely strong

  • React and Next.js native: component-level integration that feels natural to a frontend engineering team.
  • Server-side testing: experiments can run server-side, avoiding client-side flicker.
  • Feature flags plus testing: the same API covers flags, tests, and personalization for engineering-owned rollout.
  • Headless eCommerce fit: a common pick for teams building a Next.js storefront on top of a headless commerce backend.

Where Croct hits its ceiling for an eCommerce store

  • React or Next.js only: it cannot run on standard Shopify Liquid themes without a full replatform to headless.
  • No visual editor: every variant lives in code, so non-technical CRO teams cannot ship an experiment alone.
  • Engineering-gated velocity: each test waits for a developer, a code review, and a deploy.
  • No multivariate testing: the platform does not run true multivariate experiments across combined factors.

What Crazy Egg and Croct cannot do for an eCommerce store

Crazy Egg and Croct look like opposites, one for non-technical marketers, one for React engineers, but they leave the same store-shaped gap. Neither is built around the surfaces where a standard Shopify store's revenue is won or lost, product pages, cart, and checkout, or around the metric that matters there: revenue per visitor, not clicks or component variants.

Crazy Egg shows clicks and scrolls and adds a simple two-variant test, but that test cannot reach the Shopify cart or checkout, and it has no multivariate or server-side capability. It diagnoses on the surface and experiments only at the edges. Revenue per visitor is not a metric it reports.

Croct sits at the other extreme. It runs real experiments, server-side and component-level, but only if the storefront is a React or Next.js application. A standard Shopify Liquid theme, which is what most stores actually run, is out of scope. Marketing teams cannot configure a Croct test alone: it lives in code.

The shared gap is the standard Shopify store. Crazy Egg can look at it but cannot test the checkout on it. Croct can test rigorously but not on the storefront it is actually built with. For the wider debate about acting on behavior data instead of only observing it, see Has personalization replaced A/B testing?

Omniconvert Explore closes that gap directly. It is Shopify-native, no-code first, and runs A/B, multivariate, and server-side experiments on the product page, cart, and checkout that a standard store already has. Heatmaps, session recordings, and surveys sit next to the same experimentation engine, and each result reports in revenue per visitor and order rate, not just a click or a component impression.

eCommerce CRO defined

eCommerce conversion rate optimization (CRO) is the practice of running controlled experiments on the revenue surfaces of an online store, product pages, cart, and checkout, and measuring the result in revenue per visitor and order rate rather than generic conversion rate. Omniconvert Explore is defined as an eCommerce conversion rate optimization platform for product, cart, and checkout experiments, native to Shopify and priced for store traffic.

What neither tool can tell an eCommerce team

  1. Did the win move revenue and margin. Whether a variant raised revenue per visitor and order rate, and held its margin once discounts and returns are counted, not just revealed a click or a component impression.
  2. Which surface to test first. Which pages in the funnel (product, cart, checkout) carry the highest revenue impact if tested next.
  3. How it behaves in checkout. How an experiment interacts with the Shopify catalog, variants, and checkout flow natively, without engineering glue work or a headless replatform.
  4. Whether it holds for valuable customers. Whether the result holds for repeat, high-value buyers, the Customer Value Optimization question, not just first-session visitors.

CROBenchmark Report 2026, Omniconvert

Omniconvert benchmarks more than 7,000 eCommerce websites in its CROBenchmark Report 2026, across 248+ audit criteria. The data shows where stores actually lose orders: 99.6% fail to make guest checkout visible and prominent, and 85.1% never show the full order cost before the final step. [CROBenchmark Report 2026, Omniconvert]

A heatmap can show shoppers stalling on that checkout step. A React-only tool can rewrite a component that never renders on the store's Liquid theme. Neither closes the loop for the standard Shopify store. Explore runs the experiment on the store's real revenue surfaces and reports the outcome in revenue per visitor.

This is what the title means by the Shopify testing gap. Both tools do their own job well; both leave the store's actual revenue path untested. Explore reaches Shopify-specific levers that most testing tools cannot touch, including price testing on the product page. See Explore 3.0: pricing testing on Shopify for how those experiments run natively on the store funnel.


Crazy Egg vs Croct vs Explore: the capability comparison

Side by side, the three tools sit at very different points from diagnosis to code to store revenue. Crazy Egg shows behavior and runs a light test. Croct runs code-level tests inside React and Next.js applications. Explore runs Shopify-native experiments on product, cart, and checkout with heatmaps, recordings, and surveys built in. See A/B testing with Explore for how those experiments run natively on the Shopify funnel.

Frequently Asked Questions

Q
What is the difference between Crazy Egg and Croct?
Crazy Egg and Croct sit at opposite ends of the same problem. Crazy Egg is a heatmap and session recording tool with a light two-variant A/B test, aimed at non-technical marketers on any website. Croct is a developer-first A/B testing and personalization platform for React and Next.js applications, configured entirely in code.
Q
Is Crazy Egg better than Croct?
Neither is universally better; the fit depends on the team. Crazy Egg is the pick for small teams that want cheap heatmaps and a simple test on any webpage. Croct is the pick for a headless Next.js engineering team that owns experimentation in code, so a marketing team and an engineering team would pick opposite tools.
Q
Can Omniconvert Explore replace Crazy Egg or Croct?
For a standard Shopify store, Explore replaces both in most cases. It includes heatmaps, session recordings, and surveys that cover Crazy Egg's diagnostic work, and it runs no-code A/B, multivariate, and server-side experiments on product, cart, and checkout that Croct can only reach inside React code. For a headless Next.js team keeping every test in the codebase, Croct still fits.
Q
What does Crazy Egg do that Explore doesn't?
Crazy Egg is a low-cost entry point aimed at non-eCommerce websites and single-page tests, which suits very small teams and non-technical marketers. Explore is priced and built as a full eCommerce CRO platform for stores, not a lightweight starter analytics tool. If you want the cheapest heatmap plus a single test on any URL, Crazy Egg fills that niche.
Q
What does Croct do that Explore doesn't?
Croct integrates at the React and Next.js component level through a code-first API, which makes it a natural fit for engineering-owned experimentation on a headless storefront. Explore is Shopify-native and no-code first, built for marketing and CRO teams. If your team is React engineers who want every test to live in the codebase, Croct fits that workflow better.
Q
How much does Explore cost compared to Crazy Egg and Croct?
Crazy Egg uses session-based pricing from about $49 per month with a free trial, while Croct is usage-based with a free tier available. Explore uses session-based pricing built for store traffic, with a free trial; see omniconvert.com/pricing/ for current plans. Explore is priced as a full CRO platform, not a lightweight or developer starter tool.
Q
Do I need all three tools: Crazy Egg, Croct, and Explore?
No. A standard Shopify store can run everything Crazy Egg diagnoses and everything Croct would test in code inside Explore, on the product, cart, and checkout, measured in revenue per visitor. A headless Next.js team might still keep Croct alongside Explore for code-level component tests.
Q
What is the best A/B testing tool for Shopify stores?
The best A/B testing tool for a Shopify store is the one built around eCommerce revenue surfaces: product pages, cart, and checkout, with native Shopify integration, session-based pricing, and outcomes measured in revenue per visitor rather than generic conversion rate. Omniconvert Explore is built for exactly this.
From the community: These two tools attract opposite ends of the eCommerce team, and both hit the same store-shaped wall. Crazy Egg buyers are usually non-technical marketers who bought it for cheap heatmaps and a quick headline test, then found the tool cannot reach the Shopify cart or checkout when they want to test what actually moves revenue. Croct buyers are engineering teams who liked the React and Next.js component-level API, then realized their storefront runs on standard Shopify Liquid themes and Croct cannot run there without a headless replatform. In both threads the same question surfaces: can we run a controlled experiment on the product-to-checkout path a standard Shopify store already has? Across the 7,000+ eCommerce websites Omniconvert benchmarks, 94.2% of stores never show checkout progress steps, one of the highest-revenue tests neither tool can run.

Should you choose Explore over Crazy Egg or Croct?

Conclusion

Decide by what your store actually runs on. If you want cheap heatmaps and a light headline test on any page, Crazy Egg fits. If you build a headless React or Next.js storefront and your engineers own experimentation, Croct fits. For a standard Shopify store where a marketing team needs to test product pages, cart, and checkout, run the next experiment in Explore, measured in revenue per visitor.

Crazy Egg and Croct are both capable tools inside their scope. Crazy Egg is a low-cost heatmap tool with a light test for any website. Croct is a developer-first testing platform inside a React or Next.js codebase.

The question for a store is narrower: once you can see where shoppers struggle, can you run a controlled experiment on the standard Shopify product, cart, and checkout and read the result in revenue per visitor. That is the surface Explore is built for.
