whoiz

Pretty whois for humans. Bulk lookups, EPP status decoding, redemption-period explanations, and a one-keystroke jump to a registrar when a domain is free.

npx @egebese/whoiz google.com

Features

• Bulk lookups — whoiz a.com b.io c.shop runs in parallel.
• Field queries — whoiz a.com status,period shows only what you asked for.
• EPP status decoder — every clientTransferProhibited etc. comes with a plain-language explanation.
• Lifecycle awareness — knows the difference between redemptionPeriod, pendingDelete, auto-renew grace, and gives an ETA for when a domain becomes registerable again.
• Available? Browser opens. — when a domain is free, whoiz opens a Spaceship search so you can grab it in one step. (--no-open to disable.)
• TUI mode — whoiz a.com b.com --tui for an interactive Ink-based viewer.
• Background watch — whoiz watch add domain.com installs a launchd / Schtasks / systemd-timer agent that re-polls on an adaptive cadence (weekly when 6 months out, daily near expiry, every 6h in redemption) and notifies on state change. Auto-uninstalls when nothing's left to watch.
• WHOIS history — every probe writes a snapshot, whoiz history domain.com shows every registrar / nameserver / status change since you started watching.
• Foreground watch — whoiz a.com --watch re-polls in place, default every 60s, for live monitoring in a terminal pane.
• ccTLD-aware — falls back to system whois for TLDs like .tr, .de, .fr, .nl, .it, .ru and decodes their non-EPP status codes.
• Shell completion — whoiz --completion bash|zsh|fish ships ready-to-source scripts.
• JSON output — --json for scripting.

Install

# one-off via npx
npx @egebese/whoiz google.com

# or install globally
npm i -g @egebese/whoiz
whoiz google.com

The CLI command is whoiz regardless of how you install it.

Usage

whoiz <domain> [<domain> …] [fields]

Single lookup

whoiz cloudflare.com

Bulk

whoiz cloudflare.com vercel.com github.com

Field-only output

Both comma and slash separators work:

whoiz google.com status,period
whoiz google.com status/period/expiry
whoiz google.com -f registrar,ns

Available field tokens: status, period, expiry, created, updated, registrar, ns, dnssec, links, raw.

TUI mode

Bare whoiz (no arguments) launches the interactive TUI. You can also start with domains preloaded:

whoiz                       # empty TUI, type to query
whoiz --tui                 # same thing, explicit
whoiz cloudflare.com --tui  # preload one or more lookups

In the TUI:

• Type a domain (or several, separated by space/comma) and press Enter to look up.
• Tab / Shift+Tab — switch between previous lookups.
• Ctrl+O — open the current domain on Spaceship in your browser.
• Ctrl+D — drop the current entry from history.
• Esc or Ctrl+C — quit.

JSON

whoiz cloudflare.com --json

Disable browser auto-open

whoiz somenewname.io --no-open

Force the register flow

whoiz mybrand.shop -r

Foreground watch

Polls the same domain(s) on a schedule and redraws the box in place. Best for short-lived monitoring inside a terminal — for set-and-forget monitoring use whoiz watch add (below).

whoiz google.com --watch              # every 60s (default)
whoiz google.com --watch -i 30        # every 30s
whoiz a.com b.com --watch -i 600      # check both, every 10min

Stop with Ctrl+C.

Background watch (launchd / Schtasks / systemd)

Adds a domain to a tiny on-disk watchlist and registers a single OS scheduler entry that wakes once an hour to process due entries. The polling cadence is adaptive:

Time-to-expiry	Probe every
> 1 year	30 days
180 d – 1 y	14 days
30 – 180 d	7 days
14 – 30 d	2 days
3 – 14 d	1 day
≤ 3 d / hold / redemption / pendingDelete	6 hours

whoiz watch add mydomain.com                 # start watching
whoiz watch add a.com b.com --note "personal"
whoiz watch list                             # see tier + next probe
whoiz watch run mydomain.com                 # manual probe now
whoiz watch remove mydomain.com              # stop watching
whoiz watch status                           # is the scheduler installed?
whoiz watch doctor                           # detailed diagnostics + recent log

Notifications use the OS-native channel — osascript display notification on macOS, Windows.UI.Notifications on Windows, notify-send on Linux — so no extra dependencies. State lives in ~/.whoiz/.

Self-cleaning: when the last watch is removed (or a watched domain becomes available) the scheduler entry is uninstalled automatically. Nothing keeps running once you've stopped watching.

Resource cost: hourly wake, ~50 ms of work per fire if nothing is due. Mac and Linux entries are marked LowPriorityIO / IOSchedulingClass=idle; Windows is LIMITED privilege.

History

Every probe (foreground or background) records a normalized snapshot to ~/.whoiz/history/<domain>.jsonl. whoiz history walks that and shows only the changes between snapshots:

whoiz history mydomain.com
whoiz history mydomain.com --json

2026-02-15T00:00:00Z  3 changes
  registrar  OldReg → NewReg
  expiry     2026-12-31T00:00:00Z → 2027-12-31T00:00:00Z
  ns         +c.example.com  -b.example.com

2026-04-01T00:00:00Z  2 changes
  state      registered → redemption
  statuses   +redemptionperiod  -clienttransferprohibited

History is local-only — there's no service to query for retroactive data, but once a domain is on your watchlist whoiz will catch every registrar / NS / status / expiry change going forward.

Shell completion

# bash
whoiz --completion bash > /usr/local/etc/bash_completion.d/whoiz

# zsh
whoiz --completion zsh > "${fpath[1]}/_whoiz" && compinit

# fish
whoiz --completion fish > ~/.config/fish/completions/whoiz.fish

How the lifecycle is interpreted

State	Meaning
AVAILABLE	TLD's whois says no record exists. Register link opens automatically.
REGISTERED	Active registration; expiry countdown shown.
REDEMPTION	redemptionPeriod set — owner can restore for a high fee, public can't grab.
PENDING DELETE	pendingDelete set — drop in ~5 days, then public registration opens.
PENDING TRANSFER	pendingTransfer set — transfer in flight (~5 days).
HOLD	clientHold / serverHold set — DNS suspended.
