Subdomain Finder

Enumerate a domain's subdomains from Certificate Transparency logs, with an optional live DNS resolve.

What counts as one checked domain

One domain enumerated for ALL its subdomains from CT logs (optionally DNS-resolved) in a single record, however many subdomains it has. Failures recorded free.
