How useful was the Username Generator?

3

Add a keyword (optional)

Type your name, hobby, or brand word to personalise results. Toggle numbers, leet speak, separator, and case format to refine the style.

Click Copy on any card or heart it to save to Favourites. Use the platform check links to open that username's profile page and see if it's taken.

Frequently asked questions

Everything you need to know about choosing the perfect username.

A great username is short (under 15 characters is ideal for cross-platform use), easy to spell and say, memorable, and reflective of your personality or brand. Avoid using your real full name, date of birth, or location — these can link your accounts together and make you easier to track. Don't use numbers that look like substitutions for letters unless you want a specific aesthetic. The best usernames are the ones people remember after seeing them once.
Character limits vary by platform: X / Twitter — 15 characters (the tightest); Instagram — 30 characters; TikTok — 24 characters; Reddit and Roblox — 20 characters; Twitch — 25 characters; YouTube — 30 characters; Discord — 32 characters; GitHub — 39 characters; Steam — 32 characters. This generator enforces the selected platform's limit so every result you see will fit.
Each username card has a small platform check link — clicking it opens that platform's profile page for that username. If the page shows "user not found" or a 404 error, the username is likely available. This tool cannot do a real-time availability API check (which would require server calls), but the platform links are the fastest way to verify. It's also worth checking a username you like on all platforms even if you only plan to use one — securing it everywhere protects your brand.
Leet speak (or "l33t sp34k") replaces standard letters with visually similar numbers or symbols: a→4, e→3, i→1, o→0, s→5. It's useful when your preferred username is already taken — for example, if "dragon" is taken, "dr4g0n" may not be. It also makes your username harder to link to other accounts across platforms, improving privacy. Use it sparingly — too many substitutions make a username hard to read and remember.
For personal branding and content creation, a consistent username across platforms helps people find you and builds recognition. For privacy and security, using different usernames on different accounts prevents people from cross-referencing your activity and linking your real identity. The right approach depends on your goals — if you're building a public persona, be consistent; if you want privacy, vary them. Never use the same username for sensitive accounts (banking, email) as for public social media.
Each vibe draws from its own curated word bank. Gamer uses words like "shadow", "blade", "nexus", "frost". Aesthetic draws from "luna", "velvet", "bloom", "mist". Tech uses "byte", "dev", "node", "cyber". Cute uses "bunny", "mochi", "pudding", "daisy". Funny combines absurd pairings. Professional uses clean, credible words. Minimal produces short, punchy names. Each vibe combines these words with prefixes, suffixes, and your keyword to produce results that actually sound like that style.
No. Everything runs entirely in your browser — your keyword and all generated names are never sent to any server. Favourites are stored only in your browser's session memory and are cleared when you leave the page. No account, cookies, or personal data are required or stored. It's completely private.
