What NerdyData is
NerdyData searches millions of live domains for technologies, scripts, and HTML used on their pages. Searches can start with technology names, code snippets, script URLs, cookie names, or HTTP headers. Its proprietary crawler renders pages, including JavaScript, and indexes source code, cookies, headers, and network requests. Advanced searches support AND, OR, and NOT, and results can be filtered by country, domain, tech spend, industry, or date added or removed. The maker describes sales prospecting, competitive adoption monitoring, and market sizing as use cases. Free Chrome and Firefox add-ons show a website’s technologies and tech spend. The company also lists Gmail, Slack, LinkedIn Audience, an API, MCP Server, and Zapier integrations. The MCP server supports several AI clients and can export matching leads as CSV or look up domain profiles with company details and spend estimates. The free account is free and includes up to 500 rows per report and a free API account. NerdyData was founded in 2013 and is headquartered in New York.
