DNS-based estimate—confirm at checkout.

Your search stays on your device
Most domain tools send your ideas to a server that can keep a record. Anti-Frontrunner doesn’t—lookups run in your browser and we never see what you type.
-
No sniping your names
We check availability through public DNS, not registrar systems. Sellers only enter the picture when you hit Register.

Real DNS, not guesswork
Your browser asks Cloudflare and Google directly whether a name is taken—across 16 popular endings, with no Anti-Frontrunner server in the middle.
Extensions Anti-Frontrunner checks
Anti-Frontrunner looks up all 16 endings below in one search—from your browser via public DNS, never our servers. “Available” means no DNS record was found; always confirm price and registration at checkout.

What does “available” mean?
It means Cloudflare or Google DNS returned no record for that name—a signal the domain may be unregistered. Parked, premium, or reserved names can still show as available or taken incorrectly. Treat results as estimates.
Why DNS instead of registrar search?
Registrar lookups run on someone else’s server and can log what you type. DNS queries leave your device directly; Anti-Frontrunner never sees your keywords. The tradeoff is accuracy versus privacy.
Does Anti-Frontrunner log my searches?
No. There is no Anti-Frontrunner backend. Queries go to public DNS resolvers; your region preference is the only setting stored locally in your browser.
Can I check a single extension?
Yes. Type a full domain like yourname.ai in the search bar, or pick an extension below and we’ll scroll you back to search with TLD priority adjusted where it helps.
