Subdomain finder.

Everything still resolving under your domain, where each one points, and whether anything is actually there.

No account, no card, no limit on how often you run it.

Usually the most interesting check

Almost every domain that has existed for a few years has something on it nobody remembers creating. A staging site from a redesign, a campaign page, a trial of a hosted tool, a redirect from a rebrand.

Every subdomain we can find that resolves
Where each one points and whether the destination still exists
Records pointing at deprovisioned third-party services, which carry a takeover risk
Whether anything is publicly indexed that probably should not be

If you run this on a domain you inherited rather than one you set up, expect to find more than you did on your own.

This is a snapshot.

It shows where things stand today, and forgets you were here the moment you close the tab. Every free checker works this way, including the well-known ones.

Watching the same domain and keeping the answers is the paid product. It starts at $15 a month and the record begins the day you do.

Check everything at once.

One check covering registration, certificate, mail, subdomains and hosting.
