FAQ
Is it free?
Yes. There are no ads, no accounts and no paid tier.
What data does it collect?
None. The domain you look up is sent only to the DNS resolver you pick (Cloudflare or Google) to get the answer. Your settings and recent lookups stay on your device. See the privacy policy.
Why does it need permission to access the current tab?
The activeTab permission lets it read the address of the tab you're on, and only when you click the icon, so it can fill in the domain for you. It can't read page content or your browsing history.
Why might results differ from my computer's DNS?
The extension asks a public resolver directly. Your network, router or VPN may use a different resolver, local overrides or split-horizon DNS, so internal hostnames may not resolve.
