Subdomain Center 💀

A Research Project by ARPSyndicate

Subdomain Center utilizes Apache's Nutch, Calidog's Certstream, OpenAI's Embedding Models & a few of our proprietary tools to discover more subdomains than anyone else.

To avoid abuse of this service, we have rate-limited to 3 requests/minute. And we apologize in advance for any unexpected downtime & delays. Our servers are often caught in a tug-of-war between an army of demanding users and a potato-powered hamster.

Command Line Utility

pip3 install puncia
puncia subdomain <domain> <output>
