What NameBio does better.
An honest comparison starts with what the other tool is genuinely good at.
Two different jobs, one decision.
NameBio answers one question better than anyone else. What did this kind of domain actually sell for? Millions of recorded sales, over $3B in reported value, and history back to the early 2000s make it the archive the whole industry quotes in negotiations.
Unique Domains answers a different question. What should you buy now? The ScreenerScreenerThe main screen for finding one-word domains: the whole catalog in one searchable table, with the evidence behind every row.Learn more covers a curated one-word catalogue with live status, ask priceAsk priceThe price the current seller is asking today. It is where a negotiation starts, not what the name finally sells for.Learn more, and renewalRenewalThe yearly fee that keeps a domain yours. You pay it for as long as you hold the name, and on some endings it costs far more than the first year did.Learn more, plus an estimated valueEstimated valueA model’s estimate of what a name could sell for. It is an estimate and nothing more: never an offer, and never a price anyone has actually paid.Learn more, and every row is evaluated for Fit, Ownership, and Risk in simple score ratings.
That makes this a pairing, not a rivalry. NameBio documents yesterday's sales. Unique Domains turns today's live supply into a decision, with RadarRadarA saved search or a naming brief that keeps running. It carries the brief, a deadline, your saved names, your finalists and a client review link, so you keep watching a market instead of rebuilding the same search.Learn more storing your search, SignalsSignalsWhat your Radars bring back: a new matching name, a price move, a status change, an expiry window closing.Learn more bringing you newly buyable matches, and WatchlistWatchlistA tracker for names you want to come back to, with your own tags and notes on each one.Learn more and PortfolioPortfolioThe workspace for the names you already own or manage, with what each one costs to hold and what it is worth.Learn more holding the calls you make.

Unique Domains pricing
One plan covers the founder running a single naming sprint and the investor who would otherwise spend hours cross-referencing past sales against live supply. The REST API is coming soon.

An annual membership around $60 to $120 per year, as of July 2026. The free tier is heavily capped at roughly 5 to 10 results per search, and saved-search alerts, bulk lookup, and export sit behind the paid membership.
If all you need is sold prices, NameBio at roughly $60 to $120 per year is the better deal, and an easy yes.
