What it is
NerdyData searches millions of live domains for the technologies, scripts, and HTML they use. Searches can start with a technology name, raw code snippet, script URL, cookie name, or HTTP header. Its crawler renders pages, including JavaScript, and indexes source code, cookies, headers, and network requests. Advanced search supports AND, OR, and NOT, with filters for 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. Integrations include Gmail, Slack, LinkedIn Audience, API, MCP Server, and Zapier. 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. A free account costs nothing and allows up to 500 rows per report, with a free API account. Basic costs $200 a month, Pro $300 a month, and Enterprise $1,000 a month. API access is pay-as-you-go and is not included with the monthly subscription. NerdyData was founded in 2013 and is headquartered in New York, United States.
