About Subfinder
ProjectDiscovery Subfinder is a fast, passive subdomain enumeration tool designed to discover valid subdomains of websites by querying dozens of online OSINT data sources, passive DNS databases, and search engine indexes. Engineered in Go, Subfinder emphasizes passive reconnaissance, meaning it discovers domains cleanly and silently without sending traffic directly to the target’s infrastructure.
