Anti-Frontrunner is a client-side domain search tool. We designed it so your searches never pass through our servers.
Nothing about your domain searches. There is no Anti-Frontrunner backend, account system, or search log.
Your browser may store a region preference (Global, US, UK, etc.) in localStorage so TLD ordering stays consistent between visits. That value never leaves your device unless you clear site data.
When you search, your browser sends DNS-over-HTTPS queries directly to:
Those providers receive the domain names you look up and your IP address, under their own privacy policies. Anti-Frontrunner does not proxy or log those requests.
If you use a URL with ?q=, the search term appears in the address bar, browser history, and any link you share. Treat shared links like any other URL that contains a query string.
Some Register links are affiliate links. When you click through to a registrar, that site’s cookies, analytics, and privacy policy apply. We do not control third-party sites.
We load typefaces from Google Fonts. Google may receive your IP address when those files are fetched. You can block this with a browser extension or network filter.
Results are DNS-based estimates, not registrar confirmations. Always verify availability at checkout.
