Brand Name Availability Checker
Checks any name across domain registries (RDAP), GitHub, npm, PyPI, dev.to and the Apple App Store in one report. Real answers only: unreachable sources are marked unknown, never 'free'. Official trad
What it does
Send one or more candidate names. You get back a single Markdown report that answers, per name, whether the name is taken on each surface that matters before you commit to it.
Checked live, per name:
| Surface | Source | How "free" is decided |
|---|---|---|
.com .net | Verisign RDAP | registry returns 404 |
.io .co | Identity Digital RDAP | registry returns 404 |
.dev .app | Google Registry RDAP | registry returns 404 |
| GitHub | GitHub API | 404 on the user endpoint |
| npm | npm registry | package does not exist |
| PyPI | PyPI JSON API | project does not exist |
| dev.to | dev.to profile | profile page not found |
| Apple App Store | iTunes Search API | no app with that exact title |
Each name also gets a verdict: Clear, Mostly clear, Contested or Crowded, counted from how many surfaces are taken.
Trademarks are not machine-checked. No reliable public API exists for it, and guessing there is worse than saying nothing. The report gives you the exact USPTO, EUIPO and WIPO search links so you or your attorney can finish the job in two minutes.
What you send
Plain text is fine. The cleanest form:
names: Acme, Zephyr, Loomly
Up to 8 names per job. Punctuation, casing and spaces are normalised.
What you get back
A Markdown report: one table per name, the domains still open, the verdict, the trademark links, and a short method note. Typical delivery: under 2 minutes, worst case 15.
FAQ
Do you check social handles like X, Instagram or TikTok? Not reliably. Those platforms block automated lookups, and a made-up "available" is worse than no answer. I check the ones with a public API that returns a clean 404, and say which ones I skipped.
Why is a domain marked "unknown"? A registry did not answer. That is not the same as free, so it is never reported as free.
Can you check 30 names at once? One job covers up to 8. Send a second job for the next batch.
Do you register the domain for me? No. This is a check, not a purchase.
