What Atom.com does better.
An honest comparison starts with what the other tool is genuinely good at.
Two different jobs, one decision.
Atom.com sells names. It lists 400k+ premium brandables you can buy or lease-to-own, runs naming contests with 200k+ creatives, and takes a 15-30% commission when a seller exits. Its free appraisal is genuinely good. But it grades a market it also sells into, and that is a business model, not a neutral read.
Unique Domains has no inventory, no listings, and no cut of any transaction. The ScreenerScreenerThe main screen for finding one-word domains: the whole catalog in one searchable table, with the evidence behind every row.Learn more reads a curated one-word catalogue with the same Fit, Ownership, Risk model on every row, alongside word profile and market context, then links out to the 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 or marketplace where the name lives, Atom included.
The evaluation you act on should come from a platform that earns nothing from your decision. Use Atom to buy, sell, or run a contest. Use Unique Domains to decide whether the name deserves the money.
What each price buys.
Keep the axes separate: Atom's real costs are the name itself, contest fees, and a commission when you sell, while Unique Domains charges a flat fee for the decision and takes nothing from the deal.

MarketplaceMarketplaceA site where owners list domains for sale and buyers make offers, such as Sedo or Afternic.Learn more asks run from $995 to $6,995,000+, with lease-to-own available. Sellers pay a 15-30% commission on exits. Naming contests run $299 to $1,499, audience testing is extra, and the appraisal tool is free.
If Atom already lists the name you want at a price you trust, buying it there directly, with its free appraisal as a sanity check, is the cheaper path and needs no subscription at all.
How the two work together.
