Sherlock online: search a username across 1,000 sites

What Sherlock does

Sherlock takes a username and checks whether a profile with that name exists on each site in its list (its README says 400+ social networks). It is free, scriptable and widely used. Like any tool of this kind it reports false hits when a site changes how it answers, so results need checking.

A username search without the terminal

TraceFind's username search checks the most-used sites from a list of about 1,000 and streams matching profiles in as they are found. Every day it tests each site with a made-up name: sites that claim a hit for a name that cannot exist are taken out, which keeps false positives down. Where a site shares them, results include the profile's name, bio, picture and links.

Verify before you conclude

The same username on two sites is not proof of the same person. Compare profile pictures, writing style, linked accounts and dates. The username OSINT guide shows how to filter false positives and try variations of a handle.

Frequently asked questions

Is there a Sherlock web version?

Sherlock is a command-line tool. TraceFind offers a username search in the browser across about 1,000 sites, with no install.

Why do username tools show false positives?

Some sites answer every request as if the profile existed. TraceFind tests each site daily with a made-up name and drops the ones that report a hit for it.
