What is NerdyData
NerdyData is a technographic search engine that scans the source code of websites to reveal which tools and platforms they run. Teams use it to build targeted lead lists based on the software their prospects already use. The database covers over 20 million sites and more than 1,000 technologies.
Overview
NerdyData lets you search the actual HTML, JavaScript, cookies, and other code fingerprints across millions of rendered webpages. You enter a technology name like Shopify or Stripe, and the engine returns every site that runs it. This makes it useful for competitive analysis, lead generation, and domain enrichment. Data updates daily to maintain accuracy. Every paid plan includes unlimited downloads, with row limits scaling by tier. A free browser extension lets you analyze any site’s tech stack while you browse. The platform focuses purely on data sourcing and does not send emails or run campaigns.
How to use NerdyData
Enter a technology or code snippet into the search bar to generate a list of matching websites. Apply filters to narrow results by company size, location, or other criteria. Export the list as a CSV and upload it to your CRM or outreach platform for downstream prospecting.
