How do I come up with a good username?

Start with something you like — your name, a hobby, an animal — and pair it with a word that fits your vibe. Type it into the generator to get combinations like 'MightyMia' or 'mia.moonlit', then pick one that's short and easy to spell.

Does it follow Instagram, TikTok and Roblox rules?

Yes. Choose your platform and every username stays within its length and character rules — for example 30 characters for Instagram, 24 for TikTok, and 3–20 with at most one underscore for Roblox.

Can it tell me if a username is taken?

No — availability can only be checked on each app. If your favorite is taken, add a number, a prefix like 'its' or 'the', or switch the format to dots or underscores.

Yes. The word lists are hand-picked and filtered, and names are checked so no rude words appear, even when words are joined. For privacy, avoid using your full name, age, or school in a username.

Is it free to use the names?

Yes. The generator is free with no sign-up, and every name is original — use it for stories, games, social media, or anything else. Everything runs in your browser.

How to choose a good username

Keep it short and easy to spell — people should be able to find you after hearing it once.
Use the same one everywhere so friends and followers recognize you on every app.
Protect your privacy. Avoid your full name, birth year, school, or city — especially for kids and teens.
Check it’s free. Popular names are often taken; adding a number or a prefix like its or the usually helps.
