Surface AI and Crazy Egg are both used to improve website conversions — but they approach the problem from fundamentally different directions. Crazy Egg is a qualitative research platform: it shows you what visitors are doing through heatmaps and session recordings. Surface AI is an experimentation platform: it runs continuous tests to find what actually converts better. Most teams need both; many start with one and later add the other.
Quick Overview
Crazy Egg is a visual analytics tool built around heatmaps, scroll maps, click reports, and session recordings. It helps teams understand visitor behavior qualitatively. It also offers basic A/B testing functionality, added to the platform after its initial launch as a behavior analytics tool.
Surface AI is an AI-driven conversion optimization platform focused on continuous multivariate experimentation. It uses bandit testing algorithms to automatically allocate traffic to better-performing variants during the test — finding winners faster without manual review cycles.

Setup and Implementation
Crazy Egg installs via a JavaScript snippet added to your site's <head>. Full setup — installing the snippet, configuring recording rules, and setting up your first heatmap — typically takes 30–60 minutes. The recording settings (which pages to record, sampling rate, devices to include) require some upfront configuration to avoid capturing irrelevant sessions.
Surface AI installs via script tag, Next.js integration, or Shopify app. From install to first live experiment takes approximately two minutes. No goal configuration or campaign setup is required — the platform starts optimizing automatically once the script is running.
What Each Tool Does Best
Crazy Egg excels at:
- Understanding where visitors click, how far they scroll, and where they get confused
- Diagnosing usability problems before you know what to test
- Identifying rage clicks and dead zones that signal specific UX issues
- Building a qualitative evidence base to inform test hypotheses
Surface AI excels at:
- Running controlled experiments to determine which version actually converts better
- Continuously optimizing across multiple page variants without manual test management
- Allocating traffic intelligently to winning variants during the experiment
- Generating headline, copy, and CTA variant suggestions with AI
When to Use Each (or Both)
The most effective CRO programs use qualitative tools to inform hypotheses and experimentation platforms to validate them. In that workflow:
- Crazy Egg (or a similar heatmap tool) reveals that visitors aren't scrolling past the hero section on your pricing page — a behavioral insight
- Surface AI tests whether a shorter hero, a repositioned CTA, or different headline copy fixes the problem — a quantified answer
Teams with limited budgets typically start with whichever addresses their current gap. If you don't understand what your visitors are doing, start with Crazy Egg. If you already have qualitative insight and need to run experiments, start with Surface AI.
Pricing
Crazy Egg's plans start at $99/month (billed annually) for basic heatmaps and recordings. Higher plans include more recordings per month, more tracked pages, and team features.
Surface AI starts at $99.99/month with full A/B and multivariate testing capabilities, AI variant generation, and automated bandit optimization.
Who Should Use Each Tool?
Choose Crazy Egg if:
- You're at an early stage and don't yet understand where your conversion problems are
- You want visual insight into visitor behavior to build a qualitative evidence base
- You need session recordings to watch how real users interact with your site
- You want to supplement an existing experimentation platform with behavioral data
Choose Surface AI if:
- You already have hypotheses and want to test them at scale
- You want continuous, automated optimization without managing individual test campaigns
- Your team doesn't have bandwidth for manual A/B test management
- You want AI to generate variant ideas and deploy winners without a manual review cycle
Many teams use both tools: Crazy Egg for behavioral research, Surface AI for continuous experimentation.
