Show HN: Detect paid Cloudflare plans on any website via ECH(experiments.pawelpokrywka.com) A tool that checks if any website uses a paid Cloudflare subscription by examining their public /cdn-cgi/trace endpoint. Cloudflare only allows disabling Encrypted Client Hello (ECH) in paid plans, so sni=plaintext indicates a paid subscription. Works on any Cloudflare-proxied site. |
