Sherlock online

How Sherlock works here

Sherlock keeps a list of sites and, for each one, the rule that tells a real profile from a missing one: an HTTP status code, an error message on the page, or a redirect. We load that list from the Sherlock repository, apply the same rules, and run the checks from our servers.

Sites Sherlock itself skips for giving false positives are skipped here too. Adult sites are off, the same as Sherlock's default.

Results stream in as each batch of sites answers, so the first hits appear within seconds.

How to read the results

Found

The site answered the way it does for an existing profile. Open the link to confirm it is the person you mean.

Not found

The site answered the way it does for a missing profile.

Could not check

The site timed out, rate-limited us, or showed a bot check. This is not the same as not found.

Not valid here

The site does not allow this username format, so there was nothing to check.

What this free check cannot tell you

• A match means a profile with that name exists, not that it belongs to your subject. Common handles match many people.
• Some sites block data-centre traffic or change their pages, which shows up as Could not check or, rarely, a false match.
• Sherlock only checks that a profile exists. It does not read names, bios, or linked accounts.

When the free check is not enough

Sherlock tells you where a handle exists. SearchIn's people-search and leak providers return the profile fields, linked emails, and breach records behind it.

What people use it for

• Map where a handle appears before a deeper investigation
• Check your own or your company's handles for impersonation
• Pick the next pivot: a profile that links out to an email or a real name
