tldx

Bulk domain availability checker via RDAP, DNS, and WHOIS with prefix/suffix permutations and regex.

Desktopfreeglobal

A desktop application for bulk domain availability checks, tldx uses RDAP, DNS, and WHOIS and supports prefix/suffix permutations, regex selection, file or stdin input, and multiple output formats. It helps founders naming a product and developers automating checks to generate and verify many domain/TLD combinations quickly from the CLI; it is free, self-hosted, and does not register domains.
