Cloudflare Optics is a browser extension designed for Firefox, focusing on providing users with detailed connection and website information. It inspects incoming responses from visited websites to determine the HTTP version in use and identifies whether the site is being proxied by Cloudflare. The extension enhances user experience by offering insights into the data compression formats and server IPs utilized by the websites, making it a valuable tool for web developers and IT professionals.

In addition, if a website is using Cloudflare’s proxy services, Optics can retrieve extra information regarding the connection, such as the use of Cloudflare’s WARP or Gateway solutions. This extension operates under a subscription-based model and is categorized under Development & IT, specifically in web development, making it particularly useful for those who need to monitor and analyze their web traffic efficiently.
