About this tool

Query Cloudflare, Google, Quad9 and more in parallel. See whether DNS records have propagated worldwide. Free, no signup. DNS Propagation Checker runs in the browser on DevTools. There is no signup, and your input stays on this device unless the tool explicitly performs a live network lookup.

What this tool does not do

  • DNS Propagation Checker is a free in-browser utility, not a hosted API. It does not keep server-side history and is not a substitute for production verification in your own stack.
