How it works

From a list of names to a shortlist of domains

Bulk domain search — also called a mass, batch, or multi-domain checker — handles the whole loop from list input to registrar checkout, without the one-at-a-time grind.

Paste or upload a list
Drop a CSV or paste thousands of names — with or without extensions. Bare names get .com automatically.
Checks stream in live
Zone-file index first, then parallel DNS with DoH fallback. Every answer arrives the moment it resolves.
Filter by status, TLD, price
Slice the grid by availability, extension, or price range to surface the shortlist worth acting on.
Export CSV or buy in one click
Download the full set for the team, or open registrar checkout for the winners straight from the grid.

After the search

Available, for sale, or taken — what to do with each

Scanning the color grid is fast. The real work is deciding what to act on. Here's the playbook for each status.

Available

Standard-priced & ready to register.

Open registrar checkout straight from the grid. Compare prices before you commit — differences on the same TLD often exceed $20/year, and renewal rates rarely match the first-year offer.

For sale

Registered, but listed for resale.

The asking price shows inline, pulled from indexed marketplace listings. Compare it with similar aftermarket sales and factor in escrow fees before reaching out.

Taken

Already registered, not listed.

Click through for WHOIS — registrar, age, and expiry. Worth watching if the name might drop, or worth an offer if it's parked and idle.

Use cases

Six ways teams run bulk searches

Pick the workflow closest to your job — each card describes the use case, and the table below shows rough list sizes and the features that matter most.

Digital marketing agencies

Run competitor sweeps, campaign variations, and landing-page checks across dozens of clients. Export branded CSVs for approval and shave hours off every client project.

Domain investors & portfolio managers

Bulk-check availability across trending keywords, triage expiring portfolios, and spot aftermarket bargains before competitors do.

Enterprise brand protection

Secure your brand across every major TLD at once. Monitor typosquats, check ccTLDs for international variations, and sweep trademarks across the full extension list.

Startups & entrepreneurs

Test hundreds of potential brand names instantly. Check .com alongside .io, .ai, and .app — and lock the name before the pitch deck ships.

Web development agencies

Check availability live during client kickoff calls. Present options, verify as you brainstorm, and buy approved names on the spot.

SEO & expired-domain hunters

Shortlist candidate domains in one batch and cross-reference the for-sale tier to surface buyable names that already carry equity.

How to run a bulk domain search — 8 steps

Every step of the bulk workflow — from list import to registrar checkout — designed for speed and clarity at real-world scale.

1. Build your domain list
One name per line — spaces, punctuation, and www. prefixes are stripped automatically. Mix entries with and without extensions freely.
2. Cover the variations
Add typos, plurals, and hyphenations of the names you care about. Brand sweeps live or die on the variations you didn't think to check.
3. Stack your TLDs
Type the same name with several extensions (.com, .io, .ai, .app) to compare an entire TLD stack side by side.
4. Paste or upload
Drop the list into the box or import a CSV. Validation and dedup run as it loads — up to 5,000 domains per batch.
5. Scan the grid
Hit the arrow and watch the color grid fill in live: green available, blue for sale with its price, red taken.
6. Sort for the signal
A–Z for grouped brands, by length for the shortest names, price range when you're hunting aftermarket value.
7. Shortlist and copy
Filter to Available, copy the whole list in one click, or export the full result set as CSV for the team.
8. Buy through a registrar
Every green name links straight into registrar checkout; every blue one deep-links to its marketplace listing.

Bulk domain search FAQ

What is bulk domain search and why use it?: Bulk domain search is the fastest way to check availability for a whole list of domains at once, instead of one name at a time. Paste or upload up to 5,000 domains and see live availability, aftermarket prices, and registrar links in a single view — useful for brand-protection sweeps, portfolio audits, and keyword exploration.
How many domains can I check at once — is there a limit?: Up to 5,000 domains per batch, free. For longer lists, run consecutive batches — checks run in parallel against live DNS, so thousands of domains resolve in seconds.
Is this bulk domain checker free?: Yes — every feature is free with no signup. No paywall, no credit card, no upgrade path blocking bulk checks.
How do I check multiple domain names at once?: Paste your domains into the box (spaces, commas, or one per line) or drop a CSV file. You can mix entries with extensions (example.com) and without (example) — bare names get .com automatically, and invalid extensions are corrected against the official IANA list.
How accurate are the results?: Every answer resolves against live DNS — the same registry data your registrar uses at checkout, never a cached copy. When we can't get a definitive answer, we show the domain as taken rather than risk a false 'available', and results can be confirmed against the registry itself via RDAP.
What do the three colors mean?: Green = available to register at standard prices. Blue = registered but listed for sale on the aftermarket, with the asking price shown inline. Red = registered and not listed; click through for the WHOIS details.
Where do the for-sale prices come from?: From an index of millions of live marketplace listings, refreshed daily — auctions, closeouts, and buy-now inventory — plus direct marketplace lookups. Each blue result deep-links to the listing so you can buy or bid directly.
Can I save or export my results?: Yes — export the full result set as CSV (domain, status, price, marketplace, link) or copy every available name to the clipboard in one click.
What file format should I use for import?: CSV or plain text with one domain per line. Entries can include an extension or just the base name; whitespace, punctuation, and www. prefixes are stripped automatically before the batch runs.
Is bulk domain search good for brand protection?: It's one of the highest-leverage uses. Paste your brand plus common typos, plurals, hyphenations, and every TLD you care about. Export the taken rows as your monitoring list and the available rows as your acquisition list.
