## Description

**Cloudflare Optics** is a browser extension developed by Cloudflare, Inc. that offers insightful connection and website information while you browse. It inspects the HTTP response details such as the HTTP version (1, 1.1, 2, or 3), data compression format, and server IP address of the sites you visit.

If a website is proxied through Cloudflare, Optics further enhances your browsing knowledge by revealing additional Cloudflare-specific capabilities in use, such as the presence of Cloudflare's WARP or Gateway services for enhanced security and privacy. Optics operates by locally analyzing incoming website responses and verifying if the site uses Cloudflare's proxy infrastructure. This extension enables users to gain transparency about their browsing connections in real time, ensuring they understand how Cloudflare infrastructure is impacting website delivery and security features.

By installing Cloudflare Optics, users agree to Cloudflare’s Terms of Use and Privacy Policy, ensuring ethical and secure operation. This tool is particularly useful for security-conscious users and developers looking to monitor web connection details and Cloudflare integrations conveniently from their browser.
