[Maximum 100 domains are allowed]
A bulk domain availability check queries many TLD registries at once to tell you, for every name on your list, whether it can be registered now. Instead of checking one name at a time, you submit a batch and get a status for each: available (unregistered), registered (in active use), redemption period (recently expired, recoverable only by the original owner), or pending delete (expired and about to be released). WhoisFreaks queries 1,528 TLD registries and WHOIS servers directly, so each result reflects the current registration state rather than cached data.
Feature: Check up to 100 domains per batch through the free tool, or thousands per minute through the API
Feature: Paste your domain list directly into the input, one domain per line
Feature: Coverage spans .com, .net, .org, major ccTLDs (.uk, .de, .in, .pk), and new gTLDs (.io, .ai, .app, .shop)
Feature: Returns the live registry status of each domain on your list
For registrar checkout flows, naming platforms, and lists larger than 100, the Domain Availability API Domain Availability API checks up to 100 domains per request and returns structured availability data in JSON or XML.
Bulk availability checks matter whenever you have a list rather than a single name: a batch of startup name ideas, every TLD variation of a brand, or a set of expired-domain candidates. The four workflows below are where checking a list at once saves the most time.
Brainstorming produces dozens of name ideas, not one. Paste your whole shortlist and check .com, .io, .ai, and .co in one pass to find which names are actually free before you commit to branding. If a name is taken, pair with the Domain Typosquats Tool to find related variations.
Investors screen long lists of candidate and expiring domains to find registrable names before competitors do. Bulk checking flags which names on a drop list have moved into the add-grace period and become available. For monitoring expiring inventory, see Dropped Domain
Agencies check domain options across multiple client projects at once. Run a batch per client brief, identify the available names, and hand off a shortlist without searching each name one at a time. For registrant and expiry data on already-owned domains, use Bulk WHOIS
Protecting a brand means checking every variation: plurals, hyphenations, common typos, and every relevant TLD. Paste the full permutation set to see which are already registered (your monitoring list) and which are still open (your acquisition list) before a public launch.
WhoisFreaks queries live TLD registries and WHOIS servers rather than relying on cached data, and cross-references results with DNS resolution to reduce false positives. Because WhoisFreaks is a domain intelligence provider and not a registrar, your search list is not routed through a registrar checkout. The tool is free and returns the live registry status of every domain across 1,528 TLDs.
Availability can change in seconds during high-demand drops, so confirm a name at your registrar before paying. For lists larger than 100, the Domain Availability API checks 100 domains per request.
