Detect Cloudflare products and related web technologies using private, local browser signals. Techflare is a privacy-first developer tool that identifies browser-visible Cloudflare products used by websites. Open a website and click the Techflare toolbar button. The icon turns orange when at least one confirmed signal is found. The popup lists detected products, explains the evidence behind each result, and provides links to official documentation. Detectable products include: - Cloudflare Network and CDN Cache - Images and Stream - Turnstile, Access, and Bot Protection - Web Analytics and Zaraz - Pages, Workers, and R2 on official Cloudflare service hostnames - Waiting Room, Load Balancing, Rate Limiting, and Always Online Privacy by design: - Detection runs entirely inside the extension - No account, telemetry, analytics, DNS lookup, or server upload - No browsing data leaves your device - Results are retained only for the current browser session - Cookie values, query strings, Ray IDs, signed media tokens, and full resource URLs are never stored As pages load, Techflare observes requested hostnames, selected response-header presence, canonical DOM markers, and a small allowlist of Cloudflare cookie names. It does not store cookie values or page content. Techflare reports only documented, product-specific signals visible to a browser. “Not detected” does not mean that a product is disabled. Services that cannot be reliably identified—including WAF, DDoS protection, Argo, Tunnel, API Shield, and custom-domain Workers, Pages, or R2 deployments—are intentionally not guessed. Techflare uses an original icon and is not affiliated with, endorsed by, or sponsored by Cloudflare, Inc. Built by Listen Notes.
