About this project
Browser caching, DNS propagation and the like can make it tricky to tell if Cloudflare is enabled correctly. This tool will make it easier — the only caveat is that the DNS must have propagated to our networks. By scanning a website you are agreeing to our usage policy.
Some websites use asset domains
(e.g. https://static.domain.com/image.jpg) that use Cloudflare instead of their primary domain, so you may need to check these as well. You can enter full file URLs to check if a particular file is served by Cloudflare.
Find out how and why we created this tool over at our studio blog.
