domainhack
Find domain hacks hiding in real words, and check them live against the registries.
Some words have a secret: they end in a top-level domain. The Spanish word plato (plate) becomes pla.to. Abasto (supply) becomes abas.to. Grato (pleasant) becomes gra.to. domainhack finds those words, asks the registry whether each domain is really free, and tells you what to register.
Install
pipx install domainhack # or: pip install domainhack
uvx domainhack name myname # run without installing
brew install pabloalaniz/tap/domainhack # Homebrew (macOS, Linux)
Python 3.10 or newer. No API keys, no accounts, no captchas: domainhack talks to the registries directly.
Why domainhack
- It asks the registry, not a reseller. Every generic TLD is checked over RDAP through the IANA bootstrap, and 170 of the 248 country-code TLDs over RDAP or port-43 WHOIS, each verified live with a registered and a random name. Requests are paced per host, back off on 429/503 as RFC 7480 asks, and a circuit breaker skips a host that stops answering.
- It knows when "available" lies. A public-DNS cross-check flags names the registry calls free but that already have nameservers. Taken names come with their registration date, expiry date, registrar, the parking or aftermarket service behind them, and whether they are about to drop (redemption or pending delete).
- One command for a name.
domainhack name acme checks the exact name under a set of TLDs, finds hacks that spell it (acme + studio -> acmestud.io), optionally tries brand variants, and ends with a ranked recommendation.
- It works from an AI agent too.
domainhack-mcp exposes the same checks as MCP tools, so Claude or Cursor can find a domain while it helps you name a project. See Use it from an AI agent.
- It handles the hard cases. Second-level suffixes (
com.ar, co.uk), IDNs (ñandú.de), per-TLD label rules, a SQLite cache with TTLs that match how fast each kind of result goes stale, and CSV, JSON Lines, markdown and JSON output.

"Not documented" means the project's README or site did not say so in October 2026; corrections are welcome in an issue.
Find a domain for a name
You have a name and want a domain for it. One command checks the exact name under a set of TLDs, looks for domain hacks that spell it, optionally tries brand variants, and recommends what to register:
domainhack name sumanda
domainhack name sumanda --tlds startup,latam --variants --format markdown --output sumanda.csv
