Domain Hunter

Checks domain availability via WHOIS, compares prices across registrars like Spaceship and Cloudflare, and hunts down promo codes by scraping Twitter and Reddit. Generates brandable domain ideas based on your project description and won't show you anything that's already taken. The workflow is thorough: it verifies availability first, then price shops across comparison sites like tld-list.com, then digs through social media for discount codes before giving you a final recommendation with a price table. Honest about the reality that premium TLDs like .ai rarely have promos because wholesale costs are already high. Saves you the tedium of checking ten different registrars manually.

Help users find and purchase domain names at the best price.

Workflow

Step 1: Generate Domain Ideas & Check Availability

Based on the user's project description, generate 5-10 creative domain name suggestions.

Guidelines:

Keep names short (under 15 characters)
Make them memorable and brandable
Consider: {action}{noun}, {noun}{suffix}, {prefix}{keyword}
Common suffixes: app, io, hq, ly, ify, now, hub

CRITICAL: Always check availability before presenting domains to user!

Use one of these methods to verify availability:

Method 1: WHOIS check (most reliable)

# Check if domain is available via whois
whois {domain}.{tld} 2>/dev/null | grep -i "no match\|not found\|available\|no data found" && echo "AVAILABLE" || echo "TAKEN"

Method 2: Registrar search page Open the registrar's domain search in browser to verify:

open "https://www.spaceship.com/domains/?search={domain}.{tld}"

Method 3: Bulk check via Namecheap/Dynadot
