One name. Every platform.
360username.com is a free set of tools for claiming a consistent digital identity — a username checker, an AI name generator, a bulk domain search, and a handful of text utilities. No account, no paywall, no upsell.
Why this site exists
Picking a name used to be a one-platform decision. Now a single identity has to survive across a dozen social networks, a code host, a newsletter, a storefront, and a domain — and the cost of getting it wrong is paid later, quietly, in split audiences and dead links.
The usual workaround is a browser session with thirty tabs open, typing the same string into thirty signup forms to see which ones bounce. It is slow, it is easy to get wrong, and it pushes people into registering a name on one platform before they know whether they can hold it anywhere else.
This site started as a personal script to answer that one question — is this name free everywhere I care about? — and grew into the tools on it now. Everything here exists because the alternative was tedious enough to be worth automating.
What you will find here
Enter one name and see where it is free across social networks, developer platforms, marketplaces, and the major domain extensions — in a single pass instead of 150 browser tabs.
Open tool →AI Name GeneratorDescribe your niche or drop in a keyword and get brandable name candidates back, each one checked for availability as it appears, so you are picking from names you can actually register.
Open tool →Bulk CheckerPaste a shortlist of up to 50 names and compare them side by side across every major TLD. Built for the naming session where you have 40 ideas and 20 minutes.
Open tool →Unicode Text GeneratorConvert plain text into gothic, cursive, small caps, monospace and other Unicode letter styles for bios and profiles on platforms that do not support formatting.
Open tool →Invisible CharactersCopy zero-width spaces, Hangul filler and other blank code points for blank display names and spacing tricks in games and chat apps.
Open tool →PUBG Name CheckerGenerate gaming handles and check them against KRAFTON's own lookup so you find out a name is taken before you spend a rename card on it.
Open tool →How the availability check actually works
We think you should know what a result means before you act on it, so here is the honest version.
For social platforms, we request the public profile URL for the handle you typed and read what comes back. A 404 or an explicit “user not found” state means the handle is very likely free. A live profile means it is taken. That is the same signal you would get by visiting the URL yourself — we just do it across every platform at once.
For domains, availability comes from registrar lookups rather than guesswork, which is why domain results are the most reliable thing on the page.
For PUBG, the check goes through KRAFTON’s own player lookup, so a “taken” result reflects their live data.
Where this method has limits
- Reserved and banned names look free. A handle can return a 404 and still be blocked at signup because the platform reserves it, or because it was released from a suspended account.
- Rate limiting and geoblocking can produce false results. If a platform throttles us, we would rather show an uncertain state than invent a confident one.
- Availability is a snapshot, not a hold. Nothing here reserves a name. A handle that is free when you search can be gone an hour later.
- Platforms change their pages. When a site redesigns its profile or error pages, detection for that platform can drift until we update it.
Treat results as a strong signal that saves you an afternoon — then confirm on the platform itself before you build a brand on a name.
What we don’t do
- ✕We don’t sell or broker accounts. Buying and selling social handles violates the terms of essentially every platform, and the account can be reclaimed after money changes hands. We will not help with it.
- ✕We don’t require an account. There is no signup on this site. Every tool works anonymously, which also means there is no user database here to leak.
- ✕We don’t sell your searches. Queries are processed to return your results and are not sold or traded. See the privacy policy for specifics.
- ✕We don’t claim a name is legally yours. Availability is not a trademark clearance. A free handle can still infringe someone else’s mark.
How the site pays for itself
The tools are free and there is no paid tier. Running them is not free — availability checks, registrar lookups, and AI name generation all cost money per search — so the site carries display advertising to cover hosting and API costs.
Ads are labelled and kept out of the results themselves. We do not accept payment to rank a registrar higher, to mark a name as available, or to change what a tool reports. If that ever changes, it will be disclosed on this page before it ships.
Some outbound links to domain registrars may be affiliate links. They never affect availability results or pricing, and you can register anywhere you like.
About the guides
The blog covers the decisions around naming: what makes a handle last, when a personal brand beats a business name, how platform handle rules differ, and where “available” is not the same as “safe to use”.
Articles are written in-house by the person who builds the tools, based on the platform rules and registrar behaviour we deal with directly. Where an article touches trademark, legal, or financial territory, it says plainly that it is not professional advice — because it isn’t.
Platform rules change constantly. If something here is out of date or wrong, tell us and we will correct it — corrections are noted on the article.
Who’s behind it
360username.com is built and maintained by an independent developer — not a company, not a team, and not a venture-backed startup. It is a small project run by one person who got tired of checking thirty tabs by hand and kept improving the thing that replaced them.
That means fixes usually land quickly, and it also means the site is honest about its limits rather than pretending to a scale it does not have. If a platform check breaks, one person is fixing it.
Questions, corrections, bug reports, and partnership enquiries all go to the same place.
