Introducing Bulk Domain Search

We're excited to announce the launch of our new Bulk Domain Search tool, enabling domainers to search up to 1,000 domains at once.

What's New

For nearly 20 years, our Domain Search tool has expanded a single query into hundreds of domain options. Now, our new Bulk Domain Search tool consolidates hundreds of domains into a simple list. Filter by availability, price, TLDs, and more.

Whether you're working with AI-generated domain lists, migrating from spreadsheets, or checking variations of your brand, you can now validate entire lists instantly.

No signup, no payment gates. Just paste your list or CSV and instantly check availability at scale. It's 100% free.

Instead, we make commissions when people use our affiliate links to purchase domains. This helps keep our tool free forever. Thank you!

Key Features

Search up to 1,000 domains simultaneously
Import via CSV or paste directly. Our domain search tool delivers results instantly using the same sub-10ms infrastructure that powers our main domain name search tool.

Live availability preview
Domains show availability status as you type them, even before you run the bulk search.

Comprehensive filtering
Filter results by availability (available/taken/premium), TLDs (domain extensions), or price range. You can also sort alphabetically.

Export functionality
Download your domain name search results as CSV with availability status and pricing data for offline analysis.

Domain intelligence
Click into any domain to view SEO metrics including Domain Authority, backlinks, and historical data.

Use Cases

The tool addresses several specific workflows:

• Validating lists generated by LLMs or domain generators
• Checking brand variations and typos for trademark protection across all domain extensions
• Evaluating premium domain portfolios before acquisition
• Migrating from spreadsheet-based domain tracking

Privacy

The bulk search tool is powered by our own internal database of domain availability. This means no bulk queries leave our servers to retail registrars if you don't click to visit their referral links.

Getting Started

Simply navigate to instantdomainsearch.com/bulk-domain-search and start typing or paste your domain list. You can also upload a CSV file if you prefer. Results appear instantly, showing availability status for each domain. From there, filter by what matters to you - available domains only, specific TLDs, or price ranges. Click any domain to see detailed information and pricing from our registrar partners, or export everything as a CSV for further analysis.

Try It Now

We've been excited about this tool for a while. The tool is live at: instantdomainsearch.com/bulk-domain-search.

It's 100% free, and that's supported by users clicking our referral links when purchasing domains. Thanks a million for supporting our free tools!
