WHOIS for the RDAP era. DNS for the modern one.
Whodis finds the right RDAP, WHOIS, or RWhois authority automatically, then goes further with a full DNS client, domain diagnostics, batch automation, and a native desktop workstation.

// WHY IT EXISTS
I needed quick WHOIS from the shell and kept hitting RDAP and RWhois compatibility walls. I also research sites for the practical stuff: who hosts them, where mail routes, whether DNS agrees, and what is broken. Whodis is what I built for that workflow. If you do the same kind of work, it will probably fit yours too.
// TERMINAL DASHBOARD
Default view adapts: wide shells get a multi-panel mosaic, narrow shells stack the same panels. Notices stay summarized until you pass --details.
// CAPABILITIES
Automatic registration routing
RDAP when available, WHOIS when needed, RWhois for delegated networks. One query, no protocol trivia.
A full DNS client
Query any record type over UDP, TCP, DoT, DoH, HTTP/3, DoQ, or DNSCrypt. Inventory a public zone or attempt an explicit AXFR or IXFR.
DNSSEC, compare, and trace
Verify signed answers locally, compare normalized results across resolvers, and follow delegation from embedded root hints.
Native desktop workstation
Qt Widgets follows the host theme on Linux, Windows, and macOS. The bundled engine means the CLI is optional.
Batch and automation
Check many targets, pull expires or other fields, write JSON, YAML, Markdown, TSV, CSV, or raw registry text.
Actionable domain diagnosis
Run bounded DNS, reachability, HTTP, TLS, SMTP, and mail-policy checks with evidence-backed findings instead of an opaque score.
