Domain Checker — free bulk domain availability tool

📋 How this tool works Availability is checked in real time by querying domain registries directly. Results are accurate but not guaranteed — always confirm before purchasing.

Speed: ~1 second per domain — this is intentional to keep checks reliable and accurate.
Limits are in place to keep this free for everyone. Please don't run bots or automated scripts against it — abuse takes it down for all users.
Supported TLDs: .com · .net · .org · .io · .co · .app · .ai · .store · .shop · .ca. Other extensions not supported yet.
Privacy: Domain names you check are sent to our server to verify availability. Nothing is stored or logged.
