Find available single-word domains without living in registrar search boxes.

Check one word or scan 11,822 bundled names across any delegated TLD. Unclaimed uses RDAP and WHOIS, saves every result locally, and lets long searches pick up where they stopped.

Unclaimed checks domain registries directly and keeps the answers in a local SQLite catalogue. Use it for one focused lookup, a resumable word-list scan, or an interactive terminal view of the names worth keeping.

Timeouts and unclear replies stay unknown. They are never quietly reported as available.

Quick start

Requires Node.js 24 or newer.

npm i -g unclaimed
unclaimed check orbit --tlds io,ai,dev

Run unclaimed without a command to open the interactive interface. Tab moves between checking a word, browsing saved names, and updating the local catalogue.

You can also try one check without installing anything:

npx unclaimed check orbit.dev

Search more than one word

The bundled catalogue contains 11,822 common and brandable English words. sweep checks new and unresolved rows, saves each result as it arrives, and resumes safely after a stop.

.bot has RDAP but no WHOIS service. Use Namecheap bulk checks so free names can be confirmed instead of left as unknown:

unclaimed sweep --tlds bot --fast
unclaimed available --tlds bot --max-len 8 --sort commercial --limit 500

unclaimed sweep --tlds io,ai,dev
unclaimed available --sort commercial --limit 50
unclaimed available --singular --max-len 8 --no-premium

Bring your own newline-separated or JSON word list when the bundled corpus is not the right fit:

unclaimed sweep --words-file ./words.txt --tlds design,tools

Use any delegated TLD

Pass any suffix directly or load a longer list from a file:

unclaimed check orbit --tlds co.uk,design,tools
unclaimed sweep --tlds-file ./tlds.txt

Unclaimed discovers normal WHOIS routes through IANA. The local config supports explicit RDAP, WHOIS, availability-pattern, and pacing overrides for unusual registries.

Understand the answer

| Result | Meaning | | --- | --- | | available | The registry indicates that the domain is not registered. | | registered | The registry returned a record or a reserved-name signal. | | unknown | The lookup failed, timed out, was rate-limited, or could not be classified. |

Confirm an available result at a registrar before buying. Reservations, premium prices, and fresh registrations can change the final answer.

An automatic check confirms an RDAP not-found response through WHOIS. If the registry has no WHOIS service, the result stays unknown.

Install the agent skill

npx skills add iannuttall/unclaimed

The packaged skill teaches agents to use explicit commands, preserve uncertainty, and avoid running an expensive full refresh unless you requested one.
