Three steps
How it works
Get an estimated range
Enter a domain to see its estimated value, a low-to-high range, and the strength of the available evidence.
Understand the reasoning
Inspect the name's scored factors and supporting recorded sales. When close comparables are missing, treat the estimate with more caution.
Put the result to work
Save an appraisal in this browser, compare domain names, or share a certificate of the recorded result. Sign in to manage your plan and appraisal allowance.
Built for
- BuyersWeighing an offer
- SellersConsidering an asking price
- Portfolio ownersDeciding which names deserve closer research
What this is not
An estimate is a starting point for research, not a guaranteed sale price. Buyer demand, negotiation, and rights to a name still need your judgment.

Buy and sell
A domain sale where the card is held, not charged
List a name with its appraisal attached. The buyer’s card is charged only once the transfer is proven, and if nothing is proven by day 7, the hold is released and the buyer pays nothing.
- Day 0
Listed with its appraisal
The asking price sits beside the name's estimated range, so a buyer sees both.
- Day 0
Card held, not charged
The buyer pays by card. The amount is held on the card, not taken.
- Day 1-5
Transfer code handed over
The seller posts the transfer code on the order page; the buyer starts the move at their registrar.
- On proof
Charged only when it moved
On the buyer's confirmation or, up to $2,000, when the registry shows the name at the buyer's registrar and their proof record appears, or 48 hours after that move if the buyer reports no problem.
Day 7Nothing proven? The hold is released and the buyer pays nothing.
Selling
5% when it sells. Nothing to list.
Connect your own Square account: the buyer pays you directly and the money never passes through audit.domains. Card processing is Square’s, an estimated 2.9% + $0.30. Each name gets a for-sale page carrying its appraisal and DNS proof of control.
List a name for saleBuying
Pay once the name is yours.
Every listing shows the asking price beside a re-runnable appraisal and the seller’s DNS proof of control. Your card is charged only when the transfer is proven.

Every published appraisal is a deterministic estimate with factor scores and comparable sales, and anyone can rerun it.
Held-out back-test
Accuracy, measured
Nothing here asks you to take the numbers on faith. Every methodology revision is back-tested against held-out real sales before it can ship, and the full error table is public - median error, hit rates, and bias, reproducible from the committed evaluation set.

Verifiable certificates
The proof ledger
Rerunning the same domain with the same methodology, reference time, data, and settings produces the same result. Updates can change the estimate.
Certificate and integrity check
A matching digest shows that a record's contents match its supplied hash. It does not establish who issued it, the domain's sale price, or the estimate's accuracy.

Your registry computes a chain of certificate digests in this browser. A matching digest checks the record's contents; it does not establish the issuer's identity or the accuracy of its valuation.
