Find Available Domain Names
Search for available domain names that match your brand, project, or business idea.
Find Domains by Keyword
Search for available domains based on industry keywords, product names, or descriptive terms.
Quick answer: Use the Domain Search tool through ToolRouter to find domains by keyword directly from Claude, ChatGPT, Microsoft Copilot, and OpenClaw — connect once, then drive it with plain-language prompts. No code required.
ToolStarting a domain search with the right keywords is the fastest path to finding a great name. Instead of guessing at specific domains and checking them one by one, keyword-based search generates relevant options from your industry terms, product descriptions, or brand concepts.
The search_domains skill takes your keywords and finds available domains that incorporate them. Search for "coffee" and find coffeeroast.com, brewcoffee.io, or coffeelab.dev. Search for "security" and discover secureguard.io, infosec.dev, or cybershield.co. The tool explores combinations and extensions you might not think of on your own.
This approach works well at the early stages of brand development when you are still exploring naming directions. Instead of committing to a single name and finding it unavailable, start with keywords that describe what you do and let the search reveal what is possible. The available options often inspire name ideas you would never have considered.
