The verdict
Atom is a strong place to buy a brandable name and a fair place to sell one; Unique Domains is where you decide, because the platform scoring the name should not be the one selling it.
Replace or pair, depending on your job
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 Screener reads a curated one-word universe with the same Fit, Ownability, Risk model on every row, alongside word profile and market context, then links out to the registrar 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.

Marketplace 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.
How the two work together.
Nobody has to switch: founders pressure-test an Atom shortlist here before buying, and investors keep selling on Atom while sourcing their next buys with a Radar.
Step 1
Bring your shortlist
Take the names you are weighing on Atom, contest winners or marketplace picks, search each word in the Screener, and save the matches to a Watchlist with tags and notes.
Step 2
Read every row
Each matched row shows the word profile, ask versus estimated resale range, renewal cost, spread, liquidity, and risk flags, the same columns whether the name sits on Atom or anywhere else.
Step 3
Decide, then transact anywhere
Make the call with the Fit, Ownability, Risk bands, buy wherever the name lives, Atom included, and set a Radar so Signals surface comparable supply before you overcommit.
