Domain Checker tools (3)

write = sends, deletes, buys or posts

Read from the package source without running it. The installed server may list more.

  • check_domains

    Check if domains are available for registration. Uses DNS + RDAP/WHOIS for accuracy.

  • check_domains_quick

    Quick DNS-only check without RDAP/WHOIS verification. Fast but may have false positives for 'available'.

  • check_names

    Check base names across popular TLDs (e.g., ['myproject'] checks myproject.com, .io, .net, etc.)
