FAQ

Random domain generation, explained.

Random short alphanumeric domains are ideal for URL shorteners, invite links, web app short codes, gaming handles, and modern tech brands looking for concise, high-impact web addresses.
You can set the generator down to 1 character. While 2-letter and 3-letter domains in popular TLDs (.com, .io, .ai) are rarely available, targeting 4 to 6 characters yields a high rate of available, brandable domains.
Standard registration fees are per TLD extension, not character length. However, registry-designated premium short names (like 2-letter or 3-letter domains) may carry higher premium renewal and purchase prices.
Yes. Choose "Alphanumeric" to mix letters (a–z) and numbers (0–9). You can also attach static text as a prefix or suffix to lock in specific brand keywords while generating random core strings.
No. Our generator deduplicates all character outputs within a single batch run. Every click uses a fresh random seed to ensure you only see new, unique domain combinations.
