Social Media Username Generator

Generate handles that are easy to say, easy to type and structurally valid across the platforms you care about. Use Universal Strict for Instagram + TikTok + X + YouTube compatibility, or switch to a platform-specific rule set when you want more freedom.

Universal Strict modeProduces 5–15 character Latin handles using letters, numbers and internal underscores so one format can satisfy the strictest overlap of Instagram, TikTok, X and YouTube.

No fake availabilityFormat validity is not availability. #550 never claims a username is free unless the platform itself confirms it.

Taken-handle rescueTurn a claimed core handle into clean fallbacks using brand, niche, location or professional modifiers before random digits.

Sayability + future-proofingFlags punctuation load, random digits, confusing lookalikes, years, excessive length and over-local naming.

Generation is fully local. No username is sent to a platform, no account is queried, and no suggestion is labelled “available” without a real platform check.
