Score: 4.3/10 (Innovation: 4, Technical: 5, Documentation: 6, Utility: 4)

Techflare is a Chrome extension that detects Cloudflare products and technologies used by websites by analyzing browser-visible signals like hostnames, headers, DOM markers, and cookie names, all locally without any data leaving the device. It is interesting for its privacy-first approach and detailed evidence-based detection, though it serves a relatively niche audience.

Target audience: web developers, security researchers, devops
