Username Generator
Username Generator — runs in your browser. Inputs are not stored.
Username generator
Enter values, then press Calculate.
Builds ID suggestions by adding prefixes, suffixes, and numbers to the keyword. Does not check whether they are taken on real services.
How to use
- Type a word you want in Keyword. Examples are short words such as sky, 별, or coder.
- Spaces are removed; Hangul, letters, digits, dots, underscores, and hyphens are kept. Other symbols are dropped.
- Set Count. The default is 12 and the cap is 40. Anything above 40 is clipped to 40.
- Press Generate to fill the candidate box one line at a time. Prefix, suffix, number, and reversed-string patterns are mixed.
- If the keyword is empty, you are asked to enter a keyword. At least one character is required to make candidates.
- Reset clears the keyword and result area. The count field may stay as it is.
Key concepts
The username generator attaches prefixes such as the, pro, and neo, suffixes such as hub, lab, io, and kr, plus numbers and separators, to your keyword to make ID candidates. Some patterns reverse the keyword letters and append a small number.
Within one generation, the same string is not emitted twice. It does not check whether that ID exists on a real site. Check duplicates on the service before you sign up. Values stay only in the browser. Duplicates are skipped only inside the current batch; they are not compared with candidates you made earlier. Sign-up length limits, banned words, and domain availability are not checked either.
Example
Keyword star and count 12 can produce variations such as thestar, starhub, star2048, prostars, and star.io7. Hangul keywords such as 별 also work, but on sites that accept English only, an English keyword is safer. Copy a line you like, then check availability on the actual service. Keyword coder with count 12 can produce procoder, coderlab, coder391, and similar. Copy a line you like, then confirm it is free on the real site.

Frequently asked questions
Does the username generator check whether an ID is taken?
No. It only makes candidates. Check sign-up availability on that site. It cannot tell whether someone else already uses the ID.
Can I use Hangul in the username generator keyword?
Hangul is kept. Many services accept only letters and digits, though, so use an English keyword in those cases. Emoji and most special characters are dropped.
What is the maximum username generator count?
Up to 40 at a time. Duplicate lines are skipped inside the same batch. Press Generate again if you need more.
How does the name generator differ from the username generator?
The name generator combines fantasy words; the username generator attaches prefixes, suffixes, and numbers to the keyword you entered. Use one for character names and the other for IDs.
Are username generator results saved?
No. They are created only in the browser and are not sent to a server. Closing the page also clears the candidate list.
Does the username generator filter banned words or profanity?
No. It concatenates the keyword with prefixes and suffixes as-is. Read the result yourself before using it as a public nickname.
