Check up to 1,000 domains or keywords at once
Bulk TLD Check
Paste up to 1,000 keywords. See how many TLD extensions each keyword is registered under. High count means popular keyword, low count means open opportunity.

Paste up to 1,000 full domain names. See which ones are registered and which are available. Results show status, registrar, and platform info.
Which Bulk Tool Should You Use?
Bulk TLD Check is for keywords. You enter words like "coffee", "ai", "cloud" and it tells you how many TLD extensions each keyword is registered under. This helps you evaluate keyword value: a keyword registered across 200+ extensions is likely competitive, while one with only 10 registrations may be an open opportunity.
Bulk Domain Check is for full domain names. You enter "coffee.com", "coffee.ai", "coffee.io" and it tells you whether each specific domain is registered or available. This is for verifying a list you already have.
Bulk Check vs Single Domain Tools
Use bulk tools when you have a list and need status across many entries. Use single domain tools when you want detailed data on one domain (WHOIS records, DNS, backlinks, safety). Bulk gives you breadth. Single gives you depth.

When should I use bulk check instead of single domain search?
Use bulk check when you have a list of domains or keywords to verify at once. Use single domain tools when you want detailed data on one domain (WHOIS, DNS, backlinks). Bulk tools give you status across many entries. Single tools give you depth on one entry.
Do I need an account to use bulk check tools?
Guest access is available with limited daily usage. Creating a free account gives you higher rate limits and more checks per day. See pricing for details on usage tiers.
What does the TLD registration count tell me?
The TLD count shows how many extensions a keyword is registered under. A high count (e.g., keyword.com, keyword.net, keyword.org all taken) typically indicates a popular or valuable keyword. A low count may signal an opportunity to register before others do.
