AdminKit vs who.is
who.is runs a free, no-account Whois/RDAP lookup backed by over 2 billion historical snapshots since 2007 (who.is, read 2026-10-29), plus paid domain-monitoring and API tiers; AdminKit's Whois/RDAP tool is a newer, free, no-account, fully client-side live lookup with no historical archive, monitoring or API, which this page states plainly rather than implying a feature set AdminKit doesn't have.
What each tool actually shows today
A live lookup on who.is, read 2026-10-29, returned full registrar, registration/expiry dates and nameserver data for a test domain without requiring a login — the same no-account pattern as AdminKit’s Whois/RDAP tool. Both are free for a single, current-state lookup.
Where who.is goes further is depth of history and account-based features: its own homepage claims “20 years of domain data” and over “2B+ Historical WHOIS & RDAP snapshots since 2007,” and its result pages offer a paid Domain Watch alert (“part of Pro, $9.99/month”) and a programmatic lookup API (“500 free lookups a month… paid plans from $29.00/month”). AdminKit’s Whois/RDAP tool does none of that — it is a live-only lookup, run entirely from your browser via the public rdap.org proxy, with no historical archive, no account system and no API.
The honest angle
This page is not claiming AdminKit matches who.is’s historical archive, monitoring or API. If you need past registration snapshots, ownership-change alerts, or programmatic access, who.is’s paid tiers are built for that and AdminKit currently isn’t. AdminKit’s angle is a free, no-account, privacy-forward current-state lookup: the query goes straight from your browser to the public RDAP network, not through AdminKit’s own servers.

Frequently asked questions
Does AdminKit's Whois tool keep historical WHOIS data like who.is?
No. who.is's own homepage advertises "20 years of domain data" and over "2B+ Historical WHOIS & RDAP snapshots since 2007." AdminKit's Whois/RDAP tool only shows the current live record, fetched fresh from the registry each time, with no archive of past registration states.
Do I need an account to see a full result on either tool?
No, for a single lookup on either. A live test of who.is's result page for example.com showed full registrar, date and nameserver data without logging in; AdminKit's Whois/RDAP tool has no account system at all for any of its checks.
Does AdminKit offer the same monitoring and API features as who.is?
No. who.is sells a Domain Watch alert feature ("part of Pro, $9.99/month" per the result page tested) and a paid lookup API ("500 free lookups a month... paid plans from $29.00/month"). AdminKit's Whois/RDAP tool is a one-off manual check with no monitoring, alerting or API product today.
Does this page use who.is's logo or brand assets?
No. who.is is referred to by name only (nominative use) to describe and compare publicly available tools. AdminKit is not affiliated with or endorsed by who.is.
