Summary
This replaces the old whois command with a modern Go tool that gives you tabbed TUI views and JSON output for domain registration, DNS records, mail config (SPF, DMARC, DKIM), SSL certificates, HTTP headers, tech stack detection, and IP/ASN lookups. It uses RDAP first before falling back to WHOIS, so you get cleaner data for most TLDs. The JSON subcommands (quien dns, quien mail, quien tls) make it easy to script audits or pipe into jq for batch domain checks. Good for security reviews, debugging mail delivery, or just replacing your muscle memory whois alias with something that actually shows you everything in one place.
