10 bulk domain checkers worth checking out

Finding the right domain name can be tough. It has to be memorable, match your branding, and of course, be SEO friendly. When it comes to picking a domain name, you might have ideas to spare or be entirely out of them; either way, some assistance in finding the right one can come in handy.

In the case when you’re overflowing with domain name ideas, you need to narrow down your selection as much as possible. You want to get rid of the domain name ideas that are already taken, so you don’t waste time considering something that might never be available.

In the opposite situation, when the domain names you want are nowhere to be found, you need help with two things. First, with creating a proper domain name and second checking if that domain name is up for registration (and if yes, with which domain extensions).

Both generating and checking the availability of domain names are tedious tasks and can require quite a bit of time and effort on your part. Even then, you might not end up finding what you were looking for. This was probably the reasoning behind the creation of the tools we will talk about in this article – bulk domain name checkers.

Bulk domain name checkers are tools that easily take care of both generating and checking domain names. They can check (in bulk, of course) the availability of domains in full form (their name and extension), just the names, or combinations of the keywords you inserted. The fact that they do the checking in bulk is what makes them so powerful and what significantly eases and streamlines the process of checking domain name availability.

Like most software tools nowadays, there is an abundance of bulk domain name checkers on the market. Different tools, of course, come with various features and limitations. For that reason, deciding which one to go for might come as a bit of a challenge to some people. To help you at least reduce the list of possible options, in this article, we have curated a list of 10 bulk domain name checkers you might want to check out.

1. is a domain name checker that, without any fees, gives you access and unlimited usage of its domain name checking service. All you have to do is simply sign up with your email address.
The way it operates is by giving you two input boxes for inserting sets of keywords. One for a geography and industry-related keyword set, the other for any other keyword set that best describes or matches your business/website.

The number of sets isn’t limited just to the two mentioned ones, though, a third one in which you can insert any type of keywords you want can be added with just a click of a button. The domain name checker tool by generates every possible combination of the inserted keywords and checks each one for availability.

The generated domain names are either exact match domains or geo-targeted domains, but you can also review more catchy ones if prefixes like “go, my, get, fun, ultimate, major, full, free…” are added. You can choose between checking domains with the “.com” or “.net” domain name extension or a mix of domain names containing both types of extensions.

The tool will show you a list of all the combinations it has generated and will mark each one as available or unavailable, with the available ones having a link next to them, leading you to Uniregistry, where you can register the domain. The entire domain checking process is swift, and the results are automatically refreshed after you and/remove a new keyword/domain or check/uncheck a domain extension. Each time the tool completes the checking process, it will show the number of available domains and let you export them in a CSV file. Out of all of the domain name checking tools we came across, is definitely the most user-friendly and flexible one.

2. Octopoly – domain search tool

The Octopoly- domain search tool is a free bulk domain name checker provided by the Octopoly domain name registrar. Using Octopoly’s domain search tool, you can check up to 100 domain names at a time.
The inserted values can be full domains containing an extension or without an extension. In the case you are adding the domain names with extensions, they can vary, meaning that you can insert some domains with “.com” others with the “.net” extension and so on.

When you enter just the domain name without the extension, each domain name will be checked under every TLD Octopoly supports (which is over 800 TLDs). The results of the domain name checking will show, both available and unavailable domain names. In the case of an unavailable domain name, there will be an option to do a whois lookup to see the details of the current owner. The results are displayed on an endless scroll page, which will load more and more results as you continue to scroll. The tool is straightforward, with not as many features as, but still undoubtedly an excellent tool.

3. – bulk domain search

Like Octopoly, the bulk domain search tool is a service provided by a domain name registrar, the With this tool, you can search and register domain names in bulk. The number of domain names and keywords doesn’t seem to be limited, and the list of domain names/keywords you insert can be saved for later.

The search results can be filtered by manually typing in a TLD or by checking or unchecking an extension from the list of supported TLDs. You can also filter by bulk groups, which are basically domain name extensions grouped together based on a subject they all relate to, such as real estate, social, business, etc. Some of the more exciting bulk groups are the ones for legacy, ccTLDs, and featured TLDs.

One handy thing in this tool is the “show backorders” filter, which shows domains that might be available for purchase in the next five days, a.k.a. the domains that have entered the pending delete period. These are the domains you can place an early bid on before they hit the market.

After the checking process, each domain in the results is marked as either taken or available to add to the cart and also with the “premium” or “sale” tag if that is the case.

4. Dynadot – bulk domain search

Another bulk domain name checker provided by a domain registrar. The Dynadot bulk domain search tool can search up to 1000 domains at a time, complete domains, or just keywords. By checking a radio button, you will specify if you have inserted domain names with TLDs or only keywords.

In case you choose the latter, a list of available TLDs will appear in default or alphabetical order, and you will pick the ones for which you want the checking to be done. Also, if you indicated that you inserted only keywords but inserted full domains instead, the tool will disregard the extensions and check only the names.

When the search is done just for keywords, then each row of results will contain the keyword and all the TLDs you selected with either a dash in case that keyword and extension combination is unavailable or a price and checkbox in case it is available.

In case the search is done for complete domains and the domain is available, the search result will be the domain name and its price. If the domain is unavailable, it will be marked as taken and have a link for doing a whois lookup, making an offer on the domain trough DomainAgents, and the actual website.

With this tool, bulk name-checking is possible for internationalized domain names as well.

5. Rankz – bulk domain availability checker

Unlike most of the bulk domain name checkers we mentioned, this one is not provided by a domain registrar but by a site for marketing tools named Rankz. The bulk domain availability checker is one of their free tools, which can check up to 2000 domains in 30 seconds.

The thing that is different about this tool than the other ones we mentioned so far is that it can check only complete domains and not just keywords, and the complete domains have to contain one of the 45 TLDs or 12 cTLDs this tool supports. The search results are a bit more filtered off the bat, with only the available domains being displayed.

Each search result comes with a link to a domain registrar where you can purchase the domain, and the full search results list can be exported in a CSV file. This tool is maybe a bit limited, but it is indeed fast and effective at what it claims to do.

6. Namecheap – bulk domain name search

Most of us are familiar with Namecheap as one of the most famous domain name registrars in the world. Namecheap has a bulk domain name checker called “beast mode” as part of its domain name search feature. Using beast mode, you can check up to 5000 complete domains or keywords. The values can be inserted manually or uploaded in the form of a CSV file, and regardless if the values are complete domains or just keywords, your search will have the following options.

The option to choose between 471 TLDs, which are split into categories like international, academic, popular, non-English, and many more. The option to set a price range filter for the domain name that can go as low as 0$ or as high as 500.000$. The option to add prefixes and suffixes to the domain name, pre-existing ones, or your own. Lastly, the “transform” option, which will you guessed it, transforms your keywords by dropping the last vowel or by pluralizing nouns.

The results of your search can be filtered by showing or hiding premium and unavailable domains, and exported in a CSV file or shared via a link. Every available domain is displayed with its yearly price and an “add to cart” button, while the unavailable ones are marked as either taken or registered and come with a link for making an offer on the domain, again through DomainAgents.

7. Scrapebox – domain availability checker

This domain availability checker is a bulk domain name checker that comes as a part of the popular SEO tool called Scrapebox. What this bulk domain name checker has that most others don’t is the keyword scraper feature.

This feature allows you to enter keywords of your choice based on which the tool will generate even more keywords and phrases, giving you more even more ideas and flexibility when it comes to checking and picking domain names. The domain names can have a “.com”,”.net”, “.org”, or “.info” extension, and can contain hyphens. The domain availability checker allows you to add multiple custom DNS servers so that the lookup for the domain names is be done faster in rotation between the different DNS servers.

Customizable are also the whois servers for specific TLDs and will even allow you to set a delay between the whois queries for different TLDs. The search results are categorized as available and unavailable with the possibility of exporting each category separately.

8. GoDaddy – bulk domain search

Considering it is the biggest domain registrar in the world, it makes sense that GoDaddy has its own bulk domain name checker. Although GoDaddy’s is one of the simpler bulk domain name checkers, it can still check up to 500 domains or keywords and will support a large list of domain name extensions. After checking your domain names, it will group them into available and unavailable ones, with the option of adding all the available ones to your cart for registration at once.

9. NameBright – bulk check

We already wrote about NameBright, but not about their bulk checker! NameBright’s bulk check tool allows you to check 5000 complete domains or keywords with the “.com”,”.net”,”.org”,”.cc”, or “.tv” extension.

Available domains are displayed with their price and can be added to the cart in bulk or separately. The unavailable domains are displayed with a link for a whois lookup on both a registry and registrar level. The lists of both available and unavailable domains can be downloaded in CSV, XML, or XLS format, and since NameBright is a domain registrar, the available domains can be registered with them directly.

10. Domain Hole – bulk domain check

Domain Hole is a website dedicated to everything domain name related, domain name generation, expired domain name search, setting up domain alerts, and so on. It only makes sense that this type of website would also have a bulk domain checker. Like Dynadot’s bulk domain search tool, this checker requires you to insert domain names without TLDs.

If you do include TLDs, they will be stripped down from the domain name, and the domain name checking will be done for only the name and the TLDs you select from the TLD list. The results are marked as either taken or with a link saying “register,” which will lead to a GoDaddy page where you can register that specific domain name. If you sign up for a Domain Hole account, which is free, you will be able to create a list of your favorite domain names regardless if they are available or unavailable.

On the list, you can see the current availability status of each domain name and the date when you added it to the favorites list. Of course, a specific domain name can be removed from your favorites list with just a click of a button.
