What Is a Bulk Domain Checker?
A bulk domain checker is a tool that lets you check domain name availability for multiple domains at the same time, instead of searching for each name one by one. You submit a list of domain names — up to 100 at once — and the tool runs availability checks across your selected extensions simultaneously, returning results in real time.
Standard single-domain search tools require one lookup per query. A bulk domain checker parallelizes that process: checking whether example.com, example.net, example.io, and example.ai are all available takes the same amount of time as checking one domain individually.
Cloudoora’s bulk domain search tool checks availability across popular generic TLDs (.com, .net, .org, .io, .co, .ai, .app, .store) and country-code extensions simultaneously, showing available and registered status for each domain-extension combination in a single results view.
A bulk domain checker lets you:
Bulk Domain Availability Checker — Search Multiple Extensions in One Go

Real-Time Availability Results — Under 3 Seconds for 100 Domains
Each bulk availability check queries live domain registry data — not a cached database — so results reflect actual current availability. A batch of 100 domains across 4 extensions returns results in under 3 seconds. Available domains are highlighted immediately; registered domains show registration status so you can identify expiring names or backorder opportunities.
| Feature | Detail |
|---|---|
| Maximum domains per search | 100 domain names per batch |
| Lookup speed | Real-time registry queries — results in under 3 seconds |
| Extensions supported | .com, .net, .org, .io, .ai, .co, .app, .store + country-code TLDs |
| Input method | Type or paste a list, one per line or comma-separated; CSV upload supported |
| Results format | Available / Registered status per domain-extension pair |
| Free to use | No account required to run a search |
| Registration | Direct from results — no platform switching required |
| WHOIS privacy | Available at checkout for all registered domains |
Bulk Domain Registration — From Availability Check to Purchase in One Step
Once your availability check completes, select any available domains directly from your results and add them to your cart in a single action. Cloudoora’s bulk domain registration workflow skips the back-and-forth of purchasing names one by one — you confirm your selection, choose your registration period (1, 2, or 3 years), and complete a single checkout for all selected domains simultaneously.
Every domain registered through Cloudoora includes free DNS management, free email forwarding, and optional WHOIS privacy protection to keep your registration details private. SSL certificates are available to add at checkout or activate after registration from your domain dashboard.
For agencies and domain investors managing multiple client accounts or large portfolios, bulk registration eliminates the repetitive per-domain checkout process — reducing domain acquisition time from hours to minutes for large lists.
Bulk Domain Discovery Tools for Agencies, Accounts & Domain Portfolios
Bulk domain discovery is the process of identifying available domain names across a large set of ideas, keywords, or brand variations — faster than any manual search workflow allows. Cloudoora's bulk domain search tool functions as a complete domain discovery platform for teams managing multiple projects, client accounts, or domain investment portfolios.
Test dozens of startup name ideas, brand variations, or keyword combinations simultaneously. Real-time availability results help founders and brand strategists validate domain options before announcing a product name publicly — preventing the scenario where your preferred domain is registered by a third party between ideation and launch.
Compare results across extensions (.com, .io, .ai, .co) in a single view to identify which combination of name and TLD is available and best fits your brand positioning.
How to Use the Bulk Domain Search Tool — 3 Steps
From an empty search to registered domains in under 5 minutes.Add Your Domain List
Type or paste domain names into the search field — one name per line, or separated by commas. You can check up to 100 domains per search. For larger lists, upload a CSV file with one domain name per row and the tool will process your entire list in a single batch. No need to include extensions — enter base names (e.g., “mycompany”, “brandname”) and select which TLDs to check separately.
Enter Your List
Select the domain extensions you want to check (.com, .net, .org, .io, .ai, or any combination) and click “Check Availability.” Results return in real time from live registry data — typically within 3 seconds for a full batch of 100 domains. Available domains appear highlighted; registered domains show their current status. No account or login required to run a search.
Register Available Domains Instantly
Select the domains you want from your results and add them to your cart in one action. Choose your registration term (1, 2, or 3 years), add WHOIS privacy protection if needed, and complete a single checkout for all selected domains simultaneously. Free DNS management and email forwarding are included with every domain registration.
When Should You Use a Bulk Domain Checker?
Bulk domain search is most useful when you have more than a handful of domain names to evaluate — or when time-to-registration matters and manual one-by-one searching creates unacceptable delay.
Launching a Brand or Startup
Test 20–50 business name ideas at once to find one where your preferred .com and secondary extensions (.io, .co, .ai) are all available. Secure your domain before announcing the brand publicly — squatters monitor new startup announcements and register matching domains within hours of launch news.
Running Marketing or Ad Campaigns
Campaign-specific domains (promotions, landing pages, product launches) need to be registered before the campaign goes live. Bulk checking lets you evaluate and secure all campaign domains in a single session rather than repeating individual searches during campaign preparation.
Managing Client Domains as an Agency
Check and compare domain options for multiple client briefs without running separate searches per client. Upload client domain idea lists as CSV files, run availability checks in bulk, and export results for client review — reducing domain research time from hours to minutes per project.
Domain Portfolio Management
Screen large lists of candidate domain names efficiently. Domain investors looking for hand-registration opportunities can check batches of 100 names at a time, identify available names across multiple extensions, and register high-value finds before automated buyers detect and register them.
Supported TLDs and Domain Pricing
Cloudoora’s bulk domain search checks availability across the most popular generic TLDs and a growing list of country-code extensions. Pricing applies per domain per year at registration — all domains include free DNS management, email forwarding, and optional WHOIS privacy.

FAQ
Bulk domain search is the process of checking domain name availability for multiple domain names simultaneously, rather than searching for each name one at a time.

Cloudoora’s bulk domain checker supports up to 100 domain names per search. Enter names one per line or separated by commas, or upload a CSV file with up to 100 entries. For lists larger than 100 domains, split your list into batches and run multiple searches — results are available immediately after each batch completes.
Yes. Checking domain availability with Cloudoora’s bulk domain search tool is free — no account or payment is required to run availability searches. You only pay if you choose to register one or more of the available domains you discover. Registration prices vary by TLD and are shown at checkout before you confirm any purchase.
Yes. The bulk domain search tool supports CSV file uploads. Prepare a CSV with one domain name per row (base names only, without extensions — for example “mybrand” not “mybrand.com”) and upload it using the CSV import option. The tool processes your entire list in a single batch and returns availability results for all entries across your selected TLD extensions.
Cloudoora’s bulk domain availability checker supports all major generic TLDs including .com, .net, .org, .io, .ai, .co, .app, and .store, as well as country-code TLDs including .fi, .de, .uk, .ca, .se, .au, and .eu. You can select which extensions to check for each search — mixing generic and country-code TLDs in the same batch.
Bulk domain registration is the process of purchasing multiple domain names in a single checkout, rather than registering each domain individually. After running a bulk availability check, you select all the available domains you want to register, choose your registration term (1, 2, or 3 years per domain), and complete one payment for the entire selection — with free DNS management and email forwarding included for each registered domain.
Yes. Every domain registered through Cloudoora includes free DNS management with unlimited records, free email forwarding (configure multiple forwarding addresses per domain), and the option to add WHOIS privacy protection at checkout. SSL certificates are available to add at registration or activate later from your domain management dashboard — they are not included free with domain registration but are available at competitive pricing.
Cloudoora’s bulk domain checker queries live registry data in real time — not a cached database — so results reflect actual current availability. A batch of 100 domain names across four TLD extensions typically returns results within 3 seconds. Results appear as they are confirmed, so you begin seeing available domains before the entire batch completes for very large searches.
The most efficient method is to use a bulk domain checker: enter your base domain names (without extensions) into the search tool, select the TLD extensions you want to check (.com, .io, .ai, .net, etc.), and run a single availability search. This returns a side-by-side comparison of all name-extension combinations simultaneously, rather than running a separate search for each extension manually.
The bulk domain search tool is designed for checking availability and registering new domains. Domain transfers (moving domains from another registrar to Cloudoora) are handled through a separate transfer process — you will need each domain’s authorization or EPP code from your current registrar. Contact Cloudoora support to initiate a bulk domain transfer if you are moving multiple domains from another provider.
WHOIS privacy (also called domain privacy or private registration) hides your personal contact information — name, address, email, and phone number — from public WHOIS databases. Without WHOIS privacy, this information is publicly accessible to anyone who runs a WHOIS lookup on your domain. Enable WHOIS privacy during checkout when registering domains, or activate it from your Cloudoora domain management dashboard after registration.
Cloudoora’s bulk domain search tool is designed for anyone who needs to check more than a few domain names at once: startup founders validating brand names before launch, agencies checking domain availability for multiple client projects, marketers securing campaign-specific domains in bulk, and domain investors screening large lists of candidate names. The tool is free to use and requires no account to run searches.
The current limit is 100 domain names per search batch. For lists exceeding 100 domains, divide your list into batches of 100 and run multiple searches in sequence — each batch completes within seconds. If you regularly need to check more than 100 domains simultaneously, contact Cloudoora support to discuss API access options for programmatic bulk availability checking at higher volumes.
Yes. Cloudoora offers API access for developers who need to integrate bulk domain availability checking into their own tools, dashboards, or workflows. The domain availability API supports batch queries and returns real-time results in JSON format. Contact the Cloudoora team or check the developer documentation for API endpoint details, rate limits, and authentication requirements.
