## What it is
quien is a Go CLI and interactive TUI that replaces whois with a tabbed domain and IP intelligence tool covering WHOIS/RDAP, DNS, mail authentication, SSL/TLS, HTTP headers, SEO, Core Web Vitals, and tech stack detection. It also provides JSON subcommands for scripting and automated lookups.

## Use cases
- look up whois registration info for a domain
- audit SPF, DMARC, DKIM and BIMI email authentication records
- check SSL certificate expiry and SANs for a domain
- investigate IP ownership, ASN, and peering info
- run an SEO and Core Web Vitals audit on a website
- detect the tech stack behind a website
- script domain lookups with JSON output

## When to choose
- you want a modern, structured replacement for the whois command
- you need combined domain, DNS, mail, TLS, and SEO intelligence in one tool
- you want JSON output for automation and scripting
- you need IP/ASN intelligence with PeeringDB enrichment

## When to avoid
- you need a GUI or web-based domain dashboard
- you require deep bulk domain scanning at scale
- you only need a single narrow check better served by a dedicated tool

## Facets
