SpiderFoot

SpiderFoot automates OSINT collection. Give it a target (domain, IP, email, name, username, phone) and it runs hundreds of modules against public and API sources (DNS, WHOIS, certificate transparency, breach databases, social platforms, threat feeds, paste sites) and correlates what comes back into a graph and a report. Many modules need your own API keys for the underlying services.

The open source version is a Python web app you host. The commercial HX version was acquired by Intel 471 and is sold as a hosted product.
