Domain Availability Checker
Check whether domains are taken, using RDAP with a DNS fallback. Enter full domains or base names — one per line.
One per line. A line with a dot (e.g.
example.com, foo.co.uk) is checked exactly as typed.
A line without a dot (e.g. example) is a base name, checked across the TLDs below. Pasted URLs are reduced to their domain, and international names (café.com) are checked in their xn-- form.
Space- or comma-separated; the leading dot is optional (e.g.
com net org or .io, .dev). Used only for lines without a dot.

Queries use RDAP (Registration Data Access Protocol) with a DNS fallback for TLDs that run no RDAP. Nothing you type is stored or logged; all processing is stateless. A result is a strong signal, not a registrar guarantee — confirm at a registrar before you rely on it.
