How It Works
We generate 100 unique 4-letter combinations — letters only or letters+numbers — and build full domain names with your chosen TLD.
Each domain is checked in real-time via Google DNS-over-HTTPS. NXDOMAIN (Status 3) means likely available; an A record means taken.
Results stream in as each domain is checked. Available domains are sorted to the top so you can act fast. Export the full list as CSV for further research.
Always verify with your registrar before purchasing — registry propagation delays can affect results.
