How does runsonwhat know a company uses Cloudflare?
We read public traces only. For Cloudflare that means a domain-verification record in the company's DNS, the company's email records (SPF, MX, DKIM), a subdomain that points at Cloudflare, the company's DNS name servers, code loaded on the company's website, including tag managers, the website's response headers and the company's published subprocessor list. Every match keeps the record it came from.
