# NerdyData

NerdyData is a search engine for the web's source code. It lets developers, marketers, and researchers find websites that use specific technologies, code snippets, JavaScript variables, cookies, HTTP headers, or HTML patterns.

## What NerdyData does

- Search across billions of indexed web pages for any code fingerprint (HTML, JavaScript, CSS, HTTP headers, cookies, global variables).
- Identify which websites use a given technology (e.g. "find all sites running Shopify", "find all sites with Intercom installed").
- Look up the full technology stack for any domain.
- Compare two technologies side by side to see market share and overlap.
- Access data programmatically via the NerdyData API or MCP server.
