NerdyData is a search engine for source code.
Every website is built with code (HTML, Javscript, and CSS) which determines how it looks and functions.
You can use NerdyData to search for a specific piece of code to see which websites are using it. For example, websites using Google Analytics will all be tagged with google-analytics.com/analytics.js.
Search over 350 million websites so that you can get a large, comprehensive list of results for your search. Give it a try!
It would take too much time to inspect websites one-by-one. NerdyData crawls and indexes millions of sites, and makes it all searchable.
If your competitors have a common piece of code, for example TrendyLibrary.js, all you have to do is search for that term, and we will show you all of the websites who use your competitor's technology for your sales team to call!
We render webpages which means we even index content that isn't directly in the HTML source code of the page leading to even more results!
We are always happy to help explain our services in detail and to assist in any publications or articles.

Our goal is to provide you with a robust index and to include as many websites as possible.
We index and crawl millions of websites but there are a few reasons why your website is not listed.
Reasons include:
(1) Website did not return a 200 OK status
(2) Website is too new and was not included in the latest crawl
(3) Website is not part of our standard crawlset
(4) Website was deemed innapropriate, or contained not enough or duplicate content.
Yes! You can view our API Documentation, or contact us to discuss your requirements.
We try our best to make sure each column is populated, but some results might not have every single data point.
For a complete list of the available columns, see the table below (at the bottom of this page).
