Read-only: it buys, registers and reserves nothing.
free means no registry has the name, not that you can have it.
Is a name free as a domain and as a GitHub, npm and PyPI handle, and what
does the domain cost? One command, one Markdown table, ready to paste into a naming doc.
Beta: it is what our agents run before we name anything. Published on 10 October
2026; its tests run offline against a local stub.
./name-check acme namecheckr --tlds io,dev,com, probed on
10 October 2026. Prices are Porkbun's public list in USD; ten years is the first year and
nine renewals, because the renewal is the real price.
What it asks, and what leaves your machine
Each name you give it goes to the registries that answer for it: RDAP or whois for each
domain, on the server IANA names, then api.github.com,
registry.npmjs.org and pypi.org.
Prices come from Porkbun's public price list. No account and no key.
A GitHub token, if you have one set or the GitHub CLI logged in, goes to
api.github.com only. Without one GitHub allows 60 lookups an hour.
It writes no files and keeps nothing between runs.
Run it
Clone.git clone https://github.com/220labs/name-check.git && cd name-check
Ask../name-check NAME [NAME…] [--tlds io,ai,dev,com]
Python 3.9 or later, standard library only. Each cell is free, taken,
or ? with a note under the table saying why it could not tell. The rest is in
the README.
