Sublist3r is a Python command-line tool that enumerates subdomains of a target domain using OSINT sources such as Google, Bing, Yahoo, Baidu, Netcraft, VirusTotal, and DNSdumpster. It integrates the subbrute module for optional DNS bruteforce and can scan discovered subdomains against specified TCP ports.
Use cases
- enumerate subdomains of a domain for a pentest
- find hidden subdomains for bug bounty recon
- gather attack surface of a website via OSINT
- bruteforce DNS subdomains with a wordlist
- scan discovered subdomains for open TCP ports
When to choose
- you need a fast, scriptable CLI for passive subdomain discovery
- you want to combine multiple search engines and OSINT sources in one run
- you're doing reconnaissance for penetration testing or bug bounty
When to avoid
- you need active, large-scale DNS resolution at modern speed (newer tools like amass or subfinder are more maintained)
- you require Python 3.10+ compatibility or ongoing updates
- you need a GUI or API service rather than a CLI
