Left, the Unique Domains screener. Right, NameBio. Same shortlist, two very different jobs.

The verdict

Keep NameBio as your comps archive, add Unique Domains when the question shifts from what sold to what should I buy now.

Better together, most of the time.

NameBioThe comps archive
  • Strength:

    Millions of recorded sales and $3B+ in reported value, the comps everyone quotes.

  • Strength:

    Trends, bulk sold-history lookup, and a membership around $60 to $120 a year.

  • Limitation:

    Tells you what sold, not what you should buy now.

Unique DomainsThe decision layer
  • Strength:

    Live one-word evaluation with Fit, Ownability, Risk bands and market context.

  • Strength:

    Radar, Signals, and Watchlist keep the buy decision moving after the comps check.

  • Limitation:

    No sold-price archive; it reads the market forward, not backward.

What NameBio does better.

An honest comparison starts with what the other tool is genuinely good at.

The industry-reference sold-price archive: millions of recorded sales, over $3B in reported value, history back to the early 2000s

Comps everyone quotes: NameBio prices carry real weight in negotiations with buyers, sellers, and brokers

Unbeatable price for what it does, an annual membership around $60 to $120 per year

Trends reports across keywords, TLDs, and venues, including the retail vs wholesale segmentation added in 2025

Bulk sold-history lookup, vet an entire list of domains you own or are considering in one pass

Covers every reported domain sale in every niche and TLD, not only one-word domains

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 Screener covers a curated one-word universe with live status, ask price, and renewal, plus an estimated value on Pro, and every row is evaluated for Fit, Ownability, and Risk in coarse score bands.

That makes this a pairing, not a rivalry. NameBio documents yesterday's sales. Unique Domains turns today's live supply into a decision, with Radar storing your intent, Signals surfacing newly buyable matches, and Watchlist and Portfolio holding the calls you make.

What each price buys.

The two fees buy different things, so compare them by job, not by number. Explorer is free with no card: live first-page results, basic filters, one Project bundle, and 40 credits a month. A sanitized public preview at /domains needs no account at all, Pro has a 3-day trial, and Launch is a $29 one-off with no trial.

Unique Domains pricing

Launch is $29 one-off for one month of access, a single naming sprint for founders, no trial. Pro is $79/mo, or $55/mo billed yearly, with a 3-day trial, for investors who would otherwise spend hours cross-referencing sold comps against live supply. The REST API is coming soon; the AI Connector (MCP) is live on Pro.

NameBio pricing

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.

Honest concession

If all you need is sold-price comps, NameBio at roughly $60 to $120 per year is the better deal, and an easy yes.

How the two work together.

You do not migrate away from NameBio, you bring your comps habit forward in three steps.

Step01

Turn searches into Radars

Take the saved searches you run on NameBio and store the same intent as a Radar. Keywords become Screener filters plus semantic expansion over the curated one-word universe.

Step02

Let Signals surface matches

Instead of an email about a sale that already happened, Signals surface newly buyable matches from live supply, with status, ask price, and renewal on each row.

Step03

Sanity-check, then log

On Pro, compare the Screener's estimated value against NameBio comps before you commit. Then record the decision in your Watchlist, or in Portfolio once you own the domain.

Unique Domains vs NameBio, in plain answers.

Is Unique Domains a NameBio alternative?

Not really. NameBio is a sold-price archive, Unique Domains is a decision layer for live one-word domains. If you need comps, keep NameBio. If you need to evaluate what is buyable now, with Fit, Ownability, and Risk bands plus Radar alerts, add Unique Domains. Most investors run both.

Verify domain price, history, and risk before buying
What is the difference between NameBio and Unique Domains?

NameBio records what already sold: millions of transactions with price, date, and venue. Unique Domains evaluates what you can still buy: a curated one-word universe with live status, ask price, renewal, word profiles, and coarse Fit, Ownability, and Risk bands, plus Radar, Signals, Watchlist, and Portfolio to act on it.

Can I use NameBio and Unique Domains together?

Yes, that is the intended setup for investors. Find and evaluate live candidates in the Screener, let Radar generate Signals on newly buyable matches, then, on Pro, sanity-check the estimated value against NameBio's sold comps before committing. Log the outcome in Watchlist or Portfolio.

Does Unique Domains sell or register domains?

No. Unique Domains is transaction-neutral: it never sells, registers, brokers, or auctions domains. It helps you find and evaluate one-word candidates, then links out to registrars and marketplaces where the actual transaction happens.

Does Unique Domains include historical sale prices like NameBio?

No, it is not a sales archive. On Pro, each Screener row carries an estimated value as market context, which is a different tool than NameBio's record of individual transactions. For comps you can quote in a negotiation, NameBio remains the reference.

Which should a founder use to name a startup, NameBio or Unique Domains?

Unique Domains. NameBio is built for sales research, not naming. A founder starts a Project, writes a brief, watches candidates from the curated one-word universe through a Radar, and ends with a shareable finalists link. Launch covers that at $29 one-off for one month of access, no trial.
