Comparison
NameBio tells you what sold. Unique Domains helps you decide what to buy.
NameBio is the archive of record for past domain sales, the comps the industry quotes. Unique Domains evaluates live one-word domains for Fit, Ownability, and Risk, then keeps you acting through Radar, Signals, and Watchlist.
Unique Domains is not affiliated with or endorsed by any tool compared on this page. Competitor names are used for identification only. Competitor facts verified on 2026-07-15.
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
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, renewal, and an estimated resale range, 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 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
Pick the path that matches your job.
Founders
Naming a company
A sales archive will not name your startup. Start a Project, write the brief, let a Radar watch the curated one-word universe, and finish with a Brand Pack for the candidates that hold up on Fit, Ownability, and Risk. That is Launch, $29 one-off for one month.
Investors
Buying and flipping domains
Keep NameBio for comps, they carry weight in negotiations. Use the Screener and Radar for live buyable candidates, and check estimated resale ranges against sold history before you buy. That is Pro, $79/mo with a $39 intro month and a 3-day trial.
What each price buys.
The two fees buy different things, so compare them by job, not by number. There is no free tier; a sanitized public preview exists at /domains, 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 with a $39 intro month and a 3-day trial, for investors who would otherwise spend hours cross-referencing sold comps against live supply. The API is coming soon.
See full pricingNameBio 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.
How the two work together.
You do not migrate away from NameBio, you bring your comps habit forward in three steps.
Step 1
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.
Step 2
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.
Step 3
Sanity-check, then log
Compare the Screener's estimated resale range against NameBio comps before you commit. Then record the decision in your Watchlist, or in Portfolio once you own the domain.
