Checking domains one at a time is fine when you've got one name in mind. It falls apart the moment you've got a list, client name options, portfolio candidates, keyword variations from a generator. This tool takes that whole list and checks it in one pass instead of one at a time.
Paste your domains separated by commas or on separate lines, up to 1,000 in a single batch. Behind the scenes, checks run concurrently in small batches of five, so the page stays responsive instead of freezing while it works through a long list. Toggle "Hide Taken" at any point, before or during the check, to keep your view focused on what's actually available.
Paste dozens or hundreds of domains separated by commas or lines and inspect availability in one run.
Queries are executed concurrently in small batches of 5, keeping UI painting lag-free and highly performant.
Toggle visibility controls to quickly filter out taken/registered domains and isolate available names.
How to use the bulk checker
- Paste your list into the text box, comma separated or one per line
- Keep individual batches to roughly 100 to 200 domains for the fastest results
- Click Check Domains and watch results populate as each batch resolves
- Use Hide Taken to filter down to available names only
- Use Clear All to reset and start a fresh list
Getting the Most Out of a Large List
- Remove obvious duplicates before pasting, a clean list checks faster and is easier to review
- Group similar variations together (prefixes, then suffixes) so results are easier to scan by pattern
- Run a second pass on your shortlist through a blocklist and whois check before registering anything
FAQS
Is there a limit to how many domains I can check?
Up to 1,000 domains per batch. For anything larger, split the list and run it in a second pass.
Can I check domains from a spreadsheet?
Yes. Copy the column of domain names directly from your spreadsheet and paste it into the text box, each on its own line works fine.
Why do some checks take longer than others?
Checks run in small concurrent batches rather than all at once, so very long lists take proportionally longer. Keeping batches to 100 to 200 domains keeps things fast.
When should I use this instead of a single domain search?
Any time you're working from a list rather than one name, agencies comparing options for a client, or names generated through the Domain Generator.
