One name, every source at once

Unique Domains sends every name to several independent appraisers in one pass and plots their answers on a single axis. Only HumbleWorth returns a range, covering auction, marketplace and brokerage, while the others return one figure each. Where they overlap is the estimate you can explain.

HumbleWorth $6.9k to $41.8k, GoDaddy $17.4k. Illustrative example with sample figures, not a live listing. The second opinion is drawn to show how two sources read together; only HumbleWorth runs today.

The range model puts this name at $24.3k; the registrar’s own basis says $17.4k. Neither is wrong, they are answering slightly different questions. The range where they overlap is the number you can stand behind in a negotiation.

Every appraiser is looking at something different

Each appraiser was built on a different slice of the market and rewards different qualities in a name, so each is confident in a different place and blind in a different place. One number hides which of those you are looking at.

How an appraisal run works

1

Bring the names

Paste a list, upload a CSV and map the domain column, or pull the saved names of a Watchlist or a Radar. Names do not have to exist in the Unique Domains database.

2

Choose the sources

One source gives you a number. Two or more is the point of the tool: their disagreement becomes a sortable column. Only HumbleWorth answers with a range, the others return one figure each.

3

Run once

Your list is split into the batch size each source accepts and sent for you. HumbleWorth takes 100 names per request. Names appraised before come straight back from cache without a call.

4

Read them together

Each row draws the floor-to-ceiling range on one shared scale, with every other source pinned onto that same scale, so agreement and disagreement are visible at a glance.

Appraisal sources compared

No single source is authoritative, and they do not answer in the same shape. Running them on the same list is how you tell a confident number from a contested one.

Questions investors ask

Everything the appraisal actually promises, and everything it does not.

How is a domain appraised on Unique Domains?

Each name is sent to HumbleWorth’s price-predict-v1 model, run through Replicate. The model returns three figures per domain: an auction value, a marketplaceMarketplaceA site where owners list domains for sale and buyers make offers, such as Sedo or Afternic.Learn more value and a broker-negotiated price. Further sources can be added to compare independent opinions on the same name.

Is a domain appraisal a guaranteed price?

No. Every figure is a directional AI estimate trained on historical sales. It is not an offer and not a formal appraisal. The appraisal does not read the sales archive: the figure is the model's own. What names actually sold for is on the sales page. Treat it as an anchor for your own judgement.

What is the difference between auction, marketplace and broker-negotiated price?

Auction is the lowest quick-sale price, what a name plausibly fetches in a seven-day expiry auction. MarketplaceMarketplaceA site where owners list domains for sale and buyers make offers, such as Sedo or Afternic.Learn more is what a listed name plausibly closes at given patience. Brokerage is a brokered outcome to a matched end buyer: rare, slow, and the top of the range.

Can I appraise domains I do not own?

Yes. The model takes plain domain strings, so a name does not need to exist in the Unique Domains database, in your portfolio, or even be registered.

Why do two sources disagree on the same name?

Because they are answering slightly different questions. One is trained on realised sale prices market-wide, another on a single registrarRegistrarThe company you buy and renew a domain through, such as Namecheap or GoDaddy. It does not own the name, it only registers it for you.Learn more’s transactions, another on keyword demand. A tight agreement is a number you can stand behind; a wide gap usually means the name is unusual enough that no single method has much to go on.

Which appraisal sources return a range rather than one number?

Only HumbleWorth. Its price-predict-v1 model returns an auction, a marketplaceMarketplaceA site where owners list domains for sale and buyers make offers, such as Sedo or Afternic.Learn more and a broker-negotiated price for every name. GoDaddy, Estibot and DomainIndex each return a single point estimate, so on a shared axis HumbleWorth draws a bar and the others land as single points.

How many domains can be appraised at once?

Each source has its own batch size and Unique Domains splits the run to match it, with HumbleWorth accepting 100 domains per request. A 500-name list therefore becomes 5 HumbleWorth requests, handled for you. Your plan sets how many names one run can carry.

Does re-running the same name cost again?

No. A successful estimate is immutable for a given model version, so re-running the same name returns the stored figure at no cost. A new model version creates a new appraisal.

Do you sell or share the names I paste?

No. Your list is yours. Appraisal requests carry the domain strings only, with no account or portfolio context attached.

Terms on this page

Domain appraisal
An estimate of what a domain name would sell for, produced by a model or an analyst rather than by an actual sale.
Auction value
The price a name plausibly reaches in an expiry auction, where the buyers are mostly other investors.
Marketplace value
The price a listed name plausibly closes at when an end buyer eventually arrives.
Broker-negotiated price
The price a broker could negotiate with a matched end buyer, typically the top of the range.
Price gap
The distance between the floor and the ceiling estimate for one name. A wide gap signals a hard-to-sell, judgement-heavy name.
Lowest quick-sale price
The figure you could realistically convert to cash quickly, which for most domains is the auction value.
Range model
An appraiser that answers with several figures for one name instead of a single price. HumbleWorth is the only range model wired in.
Point estimate
A single-figure appraisal with no stated range around it. GoDaddy, Estibot and DomainIndex all answer this way.
Multi-source appraisal
Valuing one name with several independent methods and reading them together, rather than trusting a single tool’s output.
Realistic range
The range where independent appraisal methods overlap. Narrower than any single tool’s range and easier to stand behind in a negotiation.

Stop trusting one number.
