Domain appraisal tools: every major one compared
Every major domain appraisal tool compared: Atom, GoDaddy, EstiBot, HumbleWorth, NameWorth and more, plus human appraisals, why values disagree, and how to get a number you can trust.
Domain appraisal tools give you an instant estimate of what a domain might sell for. They're useful, free or cheap, and fast. But they disagree with each other, sometimes wildly, so the trick is knowing how to use them together. Here's every major tool, and how to get a number you can trust.
Automated appraisal tools
| Tool | What it's known for |
|---|---|
| Atom | Picked as the best overall by Domain Name Wire's 2026 review. Shows its work: comparable sales, how often the root word sells, registration counts and a separate quality "Domain Score." |
| GoDaddy Domain Appraisal | Free and quick. The dollar figures can miss, but it's good at ranking names against each other, which helps when sorting a big list. |
| EstiBot | One of the longest-running tools, popular with investors. Uses search volume, ad prices and past sales. Free searches with an account, paid plans for bulk. |
| HumbleWorth | A free AI appraiser that tends to give conservative, realistic numbers. |
| NameWorth | Automated valuations aimed at domain investors. |
| Dynadot | The registrar offers an appraisal tool alongside its search and marketplace. |
| Saw.com | A domain brokerage with its own appraisal tool. |
| Appraise.net | Known for valuations on the high side, so treat its numbers as optimistic. |
| GoExpired | Appraisals alongside expired-domain research. |
Domain Name Wire's 2026 review also looked at Appraise.software and Graen. It found several newer AI tools unreliable, including some that gave different values minutes apart or invented sales that never happened.
Human appraisals
- Sedo offers paid professional appraisals written by its staff.
- Domain brokers will often give you an honest opinion if your name is strong enough for them to sell.
- NamePros has an appraisal section where experienced investors give feedback. Blunt, but free and often very accurate.
Why appraisals disagree so much
Every tool uses different data and a different formula. Some weigh search traffic and ad prices, some lean on past sales, and some use AI models trained on very different examples. A name can show $500 on one tool and $15,000 on another. Neither is a promise. A domain is only worth what a real buyer will pay.
Watch out: be very wary of anyone who emails you an appraisal certificate, or says your domain is worth a fortune but you need to pay for an appraisal first. That's a common domain scam.
How to get a value you can trust
- Run 3 or 4 tools, including Atom and GoDaddy, and note the range rather than one number.
- Check real comparable sales on NameBio and SoldNames, with the same ending and similar length and words.
- Separate wholesale from retail. Another investor might pay 10% to 20% of what an end-user business would.
- Ask humans on NamePros if the name looks valuable.
- Set your price using our guide: what is my domain worth?

Questions
What is the most accurate domain appraisal tool?
No tool is reliably accurate. Domain Name Wire's 2026 review liked Atom best because it shows comparable sales and data. Use several tools plus real sales on NameBio.
Are free domain appraisals accurate?
They're rough estimates. Treat them as a starting point and check them against comparable sales.
Should I pay for a domain appraisal?
Only from a well-known source, like a professional appraisal from a major marketplace. Never pay a stranger who contacts you claiming your domain is worth a fortune. That's a common scam.
