Brand Name Checker: Domains, Handles, Apps & Trademarks

Send one or more candidate names. You get one report with a table per name, and the time of every check.

What we check

• Domains: default .com, .io, .ai, .co, .net. Ask for any other extension. Checked live against the registry (RDAP, or registry WHOIS when a registry has no RDAP). "Available" only when the registry says the name is not registered.
• Social handles: default X, Instagram, TikTok, YouTube, GitHub, LinkedIn. GitHub and YouTube are checked through their official APIs. Platforms with no public or permitted check (X, Instagram, TikTok, LinkedIn, Facebook, Threads, Reddit, Twitch) show "couldn't confirm" with a direct link, never a guess.
• App stores: apps with the same name on the Apple App Store (official search API) and Google Play.
• Trademarks: the USPTO trademark database (identical, contains-the-name and similar-spelling marks), each with serial and registration number, live/dead status, owner and a TSDR link. EU (EUIPO) is coming soon; other countries get a link to the WIPO Global Brand Database.
• Variations (optional): say "suggest variations" and we only list names that are free on every requested domain and every platform we can check.

How to ask

Check "Lumora" and "Brightwell" on .com, .io and .app, X, Instagram and GitHub, US trademarks. Suggest variations.

If you send only names, we use the defaults above.

FAQ

Do you register or reserve the names I search? No. We never register, reserve or buy any domain or handle, and we never share or sell the names you search. You register the names you choose.

Why "couldn't confirm" for Instagram, TikTok or X? These platforms show the same page for taken and free handles, block automated checks, or forbid them in their terms. We give you the direct link to check by hand instead of guessing.

Is "available" final? It is the state at the time shown. A registry can still reserve a domain or sell it at a premium price, and a platform can block a suspended or reserved handle.

Is the trademark section legal advice? No. Trademark results are a starting point, not legal advice. Whether a mark is "too similar" is a legal judgment; talk to a trademark attorney before you file.

How many names per job? Up to 10 names. One round of changes is included.

How fast? Usually a few minutes.
