grep(1) for the public web
Regex over the HTML and JavaScript of millions of sites, answered in milliseconds. Find every store on a platform, every page loading a script, every site sharing a tracking ID: from the browser, the API, or your agent over MCP.
Real matches from pages in Common Crawl. Every result links back to the line that matched.
Full RE2 syntax over raw page source: script tags, attributes, inline JSON, comments, anything a browser downloads.
An inverted trigram index reads only the pages that can match, so most searches come back before you lift your finger off the key.
Every search is an API call and an MCP tool. Your agent queries the same index you do, with the same credits.
