Sherlock

What it is

A Python command-line client that checks a username against a large list of social and community sites and reports where the name appears to exist. Results help map a person's or brand's public presence.

What it helps with

- Checking whether a username exists on hundreds of sites
- Building a first pass of someone's public social footprint
- Exporting hits for later manual review
- Running checks from a simple CLI on your own machine

Who it's for

OSINT investigators and analysts researching publicly available account presence.

Worth knowing

Use Sherlock only for lawful, ethical investigations. Do not use it to stalk, harass, or break a site's terms of service.

Does it log into accounts?
