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. 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.
