The domain appraisal of record

Type a domain, get the price it would likely sell for.

What is your domain
actually worth?

Type a domain and get the price it would likely sell for - based on recorded sales, not guesses. Then lock the price into a certificate anyone can check, no account needed.

For buyers, sellers, and brokers pricing a domain. Your first 3 price reports are free - no account needed. See a worked example first - no typing, no account.

How it works

You name a domain

The model prices it against real closing prices of comparable domains - not asking prices, not opinions. Same domain, same answer, every time.

You lock the price in

The price becomes a numbered certificate. It can never be quietly edited - a fresh price gets a new certificate, and the old one stays on record.

Anyone checks it

You send one link. The buyer, the broker, the bank - anyone can recompute the number themselves, live, with no account. That is the whole point.

Built for

Sellers who need a defensible ask, buyers weighing an offer, and brokers or lenders who need a number a third party will accept.

What this is not

Not a marketplace and not a broker - we don't buy, sell, or take a cut. The price report is the product, and it's the same for everyone.

Published appraisals

Published appraisals

Every published appraisal is a deterministic estimate with factor scores and comparable sales, and anyone can rerun it.

Accuracy, measured

Accuracy, measured

We don’t ask 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.

Rerun any domain and the engine returns the identical figure. Every report carries a SHA-256 digest anyone can recompute, byte for byte.

Back-tested

Every methodology revision is graded against held-out real sales before it ships. The full error table is public - median error, hit rates, and the misses.

Hash-chained

A certificate is never edited - only superseded. Your registry renders every file as a hash chain, recomputed in your browser, so a doctored figure has nowhere to hide.
