Crazy Egg
Crazy Egg is a website optimisation tool that records how visitors behave on a page: heatmaps, scroll maps, click reports, session recordings and simple A/B tests.
Websites with Crazy Egg installed are run by people who actively work on conversion: e-commerce stores, SaaS companies, lead-generation sites, agencies and marketing teams. Because it costs money every month and is useless unless someone reads the reports, its presence shows a marketing budget, measurable goals and someone responsible for the website; small brochure sites rarely carry it.
Sellers who need this audience are vendors of complementary conversion software (A/B testing, personalisation, surveys, form analytics, chat), CRO agencies and freelancers, UX research services and competing analytics suites. A site that recently added Crazy Egg has just started an optimisation effort and is collecting data it will want to act on; a site that dropped it has either finished the project or switched tools and may be comparing alternatives.
Crazy Egg is installed on 231,896 websites, which is 0.7% of all Analytics detections we record. Websites measured with Crazy Egg are most often served from United States (206,242), Germany (4,532) and Canada (3,425), and .com, .org and .net are the most common domain endings.

Questions about Crazy Egg websites
How many websites use Crazy Egg?
As of November 2, 2026, 231,896 websites load the Crazy Egg script on their homepage. The number is recalculated every night from our own crawl of the web.
Who buys lists of websites using Crazy Egg?
Vendors of analytics, A/B testing, consent and personalisation tools, agencies that sell conversion optimisation, and data products that plug into Crazy Egg. A website that measures itself has a team that looks at numbers; one that just added Crazy Egg is building that capability, one that dropped it has switched tools.
Where are Crazy Egg websites hosted?
United States leads with 206,242 websites, followed by Germany (4,532) and Canada (3,425). The country is where the website is served from; sites on a hosted platform show the platform's country.
How do I find websites that just added Crazy Egg?
The New tab on this page lists websites where our crawler saw Crazy Egg for the first time in the last days, newest first; the Dropped tab lists the sites that removed it. Both download with a subscription and refresh every morning.
How do I get a list of websites using Crazy Egg?
A free BetaScan account downloads a {sample_rows}-row sample. A subscription from $69 a month gives the full list of 231,896 domains, or a dataset with emails, phones, country, hosting and ranks, filtered by country, TLD, rank and registration date. See pricing.
How does BetaScan detect Crazy Egg?
Our crawler fetches the homepage of every domain we track and matches the page and its response headers against the signatures of 7,636 technologies. A website counts as using Crazy Egg when its latest crawl shows the signature; when the signature disappears, the site moves to the dropped list.
How can you tell a website uses Crazy Egg?
The page loads a small tracking script from script.crazyegg.com, usually a URL of the form pages/scripts/XXXX/XXXX.js that is tied to the account. It is often inserted through a tag manager, in which case it still appears in the rendered requests but not in the raw HTML. Our crawler looks for the script reference on the homepage and in the response.
What can you sell to Crazy Egg users?
Anything that turns behaviour data into changes: A/B testing and personalisation platforms, landing page builders, UX design and CRO consulting, user research panels, on-site surveys and feedback widgets, and analytics tools that go deeper than heatmaps. The account holder is usually a marketing manager or growth lead, so the buyer persona is clear.
Is Crazy Egg used by large companies or small ones?
The core audience is small and mid-sized businesses and agencies; the plans are priced for individual sites and teams rather than enterprises. Larger companies with dedicated analytics teams tend to run full product analytics or experience platforms instead. A Crazy Egg install therefore usually points to a company that is big enough to care about conversion but small enough to buy tools without a procurement process.
