N.01/07> The problem

Picking a name is the fun part. Checking it is not.

  • Fifteen tabs for one name

    A registrar for the domains, then Instagram, then X, then six more. By the time you reach the last one you have forgotten what was free at the start. Then you think of a better name and do it again.

  • Answers that look right

    A profile that loads does not mean the handle is taken, and a 404 does not mean it is free. Removed, reserved and banned handles render exactly like unregistered ones on several platforms.

  • Stale by the time you decide

    You check on Monday, sit on it, and register on Friday. Good names move in between and nothing tells you. Checking once is not the same as knowing.

Handleyo does all 25 at once, reads each platform properly rather than guessing from a status code, and gives you one straight answer per target. One name, one pass.

Five questions, asked in order.

A registrar search box asks one source and shows you what it said. This asks up to four, tries to contradict itself, and refuses to guess when none of them answer.

Ask who is authoritative

Every extension is resolved against the IANA bootstrap rather than a hardcoded list, so the lookup goes to the registry that actually runs it. A confident answer from a server that does not serve the extension is indistinguishable from a real one.

Five questions, asked in order.

A registrar search box asks one source and shows you what it said. This asks up to four, tries to contradict itself, and refuses to guess when none of them answer.

  1.  01 · BOOTSTRAP 

    Ask who is authoritative

    Every extension is resolved against the IANA bootstrap rather than a hardcoded list, so the lookup goes to the registry that actually runs it. A confident answer from a server that does not serve the extension is indistinguishable from a real one.

  2.  02 · REGISTRY 

    Ask the registry directly

    RDAP first, at the registry's own endpoint. Verisign for .com and .net, the Public Interest Registry for .org, Identity Digital for .io and .ai, Google's registry for .app and .dev. No reseller, no aggregator between the question and the answer.

  3.  03 · SECOND 

    Ask a second source

    When the first source is inconclusive the registry's WHOIS is asked on port 43, and twenty-five country extensions are answered that way as their primary source. One source that says 'not found' for everything looks perfect right until it hands somebody a free name that is not free.

  4.  04 · CONTRADICT 

    Try to prove it wrong

    A domain reported free is checked against live DNS before it is believed, because a registered domain is always delegated. Handles get the same treatment: a platform that cannot prove a name is free may only ever prove it is taken.

  5.  05 · REFUSE 

    Refuse rather than guess

    If the ladder ends without a verified answer, the result is reported as taken. Being wrong that way costs you a name you could have had. Being wrong the other way costs a registration fee, a rebrand, and the thing you were building on.

What one check covers25 targets

One name, asked everywhere at once.

Up to 4 independent sources behind a single answer, and a plain refusal when none of them can agree.

0113 extensions

Domains

Every extension is asked at the registry that actually runs it, resolved through the IANA bootstrap rather than a list we maintain. Any extension publishing RDAP can be asked for by name.

  • Registry RDAP
  • WHOIS
  • DNS check
0212 platforms

Handles

One adapter per platform, each isolated, so a platform that breaks takes nothing else down with it. Where a platform cannot prove a handle is free, it is allowed to say only that it is taken.

  • Profile pages
  • Crawler UA

The verdict

A ranked shortlist rather than a wall of ticks. The .com outweighs every other target combined, and anything we could not verify is left out of the score instead of counted against a name.

Everything here can be opened and counted.

The two figures that can drift are imported from the same file the checkers are tested against, so a platform cannot be added without this section changing with it.

Want a specific one? Type the full domain, like yourname.in or yourname.de, and it is checked alongside these.

N.05/07> Two answers

A straight answer, every time.

  • Available

    Nobody has claimed it. You are free to register the domain or create the handle.

  • Taken

    Someone already has it. Move on or pick a different name.

Domains are read from the registry itself. Handles are read from the live profile page. We never guess, so check before you register.

What it will not doNo exceptions

The limits, in the same place as the promises.

If we cannot verify it, we show it as taken.

Guessing wrong the other way costs a registration fee and a rebrand.

Every result, every target
Instagram, Facebook, Threads can only ever prove a handle is taken.

Logged out, they serve a registered account and a free one identically.

Named under your results
Results are indicative. Confirm before you register.

A 404 can occasionally mean a removed or suspended account.

Said once, under the board
We do not sell domains, and nothing here is an affiliate link.

Nothing on this page earns more when it tells you a name is free.

No registration flow, by design
Signed out, nothing you check is written down.

Signed in, it exists only so we can tell you when something frees up.

N.07/07> FAQ

Questions.

How accurate are the results?

Domains come from registry data, which is authoritative. Handles are read from the live profile page, which occasionally misreads a removed or banned account. Strong enough to decide on, worth a look before you pay.

Do you always get an answer?

Yes. Every check returns available or taken, never a shrug. If a platform blocks the first request, handleyo retries, then routes the check through a residential connection. In the rare case a platform stays unreachable, the name is shown as taken, because sending you to register a name somebody already holds is the worse mistake.

Do you store what I search?

Signed out, nothing is stored: the names are checked and not written down. Signed in, your checks are kept as a history on your account so we can tell you when something comes free, and you can switch that off or delete it whenever you like. Either way we keep a random cookie value and a one-way hash of your IP address to make the free checks run out rather than last forever. Clerk holds your account and Stripe holds the payment. We never see your card.

How many names can I check at once?

Up to 25 in a single run, on the free checks and on Pro alike. Enter more than one and handleyo ranks them against each other, with a recommended pick at the top. The difference is how many runs you get: 3 free, then unlimited on Pro.

What happens after my free checks?

You sign in and subscribe to Pro at $9 a month for unlimited checks. Cancel any time from your account, and you keep access until the period you paid for ends.

Do I need an account?

Not for your first check. That one asks for nothing at all, so you can see the tool work before deciding anything. Checks two and three are also free but need an account, and from the fourth you subscribe. All 3 free checks cover up to 25 names each, exactly like Pro.

Can I check a country domain like .in or .de?

Yes. Type the whole thing, like yourname.in, and that exact domain is checked alongside the 13 defaults. It works for every extension whose registry publishes availability data, which is over a thousand of them. For the few that publish none, we say so rather than guess.

Can I register a name through handleyo?

No. handleyo only checks availability. When something is free, we link you to the registrar or platform to claim it yourself.

Check it before you commit to it.
