How to Find All Subdomains of Any Website (Free, No Install)

Subdomains often expose forgotten staging servers, old admin panels and misconfigured services. Whether you're a bug bounty hunter, a sysadmin auditing your own domain, or an SEO checking site structure, the first step is knowing which subdomains exist.

Why subdomain enumeration matters

Security: forgotten subdomains are a common source of takeovers and leaks.
Asset inventory: teams often don't know everything they've deployed.
SEO: duplicate or stale subdomains can split your search rankings.

Method 1: Use a free online tool

The fastest way is a browser-based tool like Manamil Subdomain Finder:

Open the tool and type the domain (e.g. example.com).
Run the search.
Review the results: each subdomain shows whether it's live, its IP address, hosting country and first-seen date.

The live-status column is the useful part: you can immediately focus on the subdomains that actually respond.

Method 2: Command-line tools

If you prefer the terminal, tools like subfinder and amass are popular open-source options. They're powerful but need installation and setup.

What to do with the results

Check dead subdomains whose DNS still points somewhere (takeover risk).
Run an SSL check on live ones.
Look up ownership with a WHOIS lookup and verify records with a DNS checker.
Remove or redirect anything you no longer use.

Only scan what you're allowed to

Enumerate your own domains or targets within a bug bounty program's scope.
