Due diligence for domain names
Know what you're buying.
Before you buy an expired domain, DomainDue checks its availability, reputation, history and risks. Each finding comes with its source and date; what could not be measured is listed, not hidden.

The dossier
What a dossier answers
The same questions for every domain, in the same order, with the source of each answer.
- 01
Can I get it?
Availability and registration price at the registrars we integrate, checked live.
- 02
Is it healthy?
Email blacklists, Google Safe Browsing and VirusTotal, each with its source and date.
- 03
What happened to it?
Age, registration history and archived snapshots from the Wayback Machine.
- 04
What is it worth?
An estimate built from comparable sales, given as a range.
- 05
What don't we know?
Every signal that could not be measured is listed, so an incomplete dossier never reads as a clean one.

Questions
Before you ask
What is in a dossier?
The answers to five questions, from 14 signals: email blacklists, Google Safe Browsing, VirusTotal, traffic rank, domain age, Wayback history, trademark and ownership checks, plus Google indexation, backlinks, social presence, past content and the biography of its archived past as they are measured. Every signal shows its source and date, and an incomplete analysis is labelled as such.
How is this different from ExpiredDomains.net?
ExpiredDomains.net lists expired domains with third-party metrics and leaves the checks to you: Safe Browsing, VirusTotal, blacklist checkers and the Wayback Machine, one site at a time. DomainDue runs those checks and shows each result with its source and date.
Can I trust the result?
We pull from public, authoritative sources: Google Safe Browsing, VirusTotal, Tranco, RDAP, DNS blacklists and the Wayback Machine. Each signal comes with its source and the date it was measured. If some signals are missing, the result says 'Incomplete analysis' and lists them.
What is free?
Every feature, for every account, with 50 analyses a day: the full dossier, the daily feed, lists and alerts, bulk checks and exports. An account needs an email address you verify.
What counts as an analysis?
Each new domain you check, alone or in a bulk check, each extension counted apart. A domain DomainDue analysed recently opens again without using one, while you have analyses left.
