What we check

Adding a little sanity to domain investing

Buying a domain name without running due diligence checks is just plain nuts. In the time it would take you to open and log into a website, you can have verifiable due diligence data in the palm of your hand. Our search returns the following data:

Blacklists

Whether the domain is listed for malware or abuse — how many URLs, when the listing started, and a link straight to the record so you can see it for yourself.

Registration

Registrar, creation and expiry dates, nameservers and transfer status. Whether it's available, taken, or about to lapse.

Ownership history

Who held it before, how often it changed hands, and when its infrastructure moved — deduplicated so a registrar renaming itself doesn't look like a sale.

Trademark

Live US marks matching the name, with owners and registration classes. It shows you the records; it does not pretend to clear a name.

DNS & mail

Where it points now, where its mail goes, whether it resolves at all — and whether it's been quietly parked.

Archive history

How far back the public web archive goes for this domain, and a tap straight through to browse what it used to look like.

Market estimates

Independent value estimates shown side by side — and when they disagree, we say so instead of averaging them into one confident-looking number.

Why it's different

Findings you can check, not a score you have to trust

No number to hide behind

There's no 0–100 score. A single figure averages an active malware listing and a thin archive into the same result. You get the findings, and you decide.

It won't tell you to buy

Whether a live trademark or a sketchy past owner matters depends on what you intend to do with the name — which only you know. Domainity reports; you judge.

Sources are tested, not trusted

Every data source is checked on a schedule against domains known to be malicious. One widely used commercial API failed that test and was dropped before launch.

An unanswered check is never a pass

If a source times out or rate-limits, the report says so on the same line as the results. You always know how much of the picture you're actually looking at.

Where that last one came from

Domainity began as a private tool that got this wrong. In a run across 211 domains, three came back marked available to register — because the lookup had failed, and the failure was read as an answer.

Nothing in the output said anything was missing. That defect is the reason for every design decision above, and it's why a failed check is now the loudest thing on the screen instead of the quietest.
