ToolsHub
Discover subdomains instantly from Certificate Transparency
Discover subdomains for any domain using public Certificate Transparency logs. Fast, passive, and free. Perfect for security audits, penetration testing, OSINT, bug bounty hunting, and infrastructure discovery—without actively scanning the target.
Hey Product Hunt! 👋
Today I'm launching Subdomain Finder by ToolsHub.
While working on infrastructure and security projects, I found that many existing subdomain tools were either slow, overloaded with ads, required signups, or relied on noisy active scans.
So I built a clean, fast, and completely free alternative that uses Certificate Transparency logs to discover public subdomains without sending traffic to the target.
I'd love your feedback on:
• Speed and usability
• Features you'd like to see
• Export formats (CSV, JSON, TXT)
• Additional passive data sources
• API access
If you work in cybersecurity, DevOps, networking, bug bounty hunting, or web development, I'd love to hear how you would use it.
Thanks for checking it out!
