Our Take

Sherlock has racked up 78.7k GitHub stars because it solves a problem that actually matters: with a single command, you can check whether a username exists across 400-plus social platforms simultaneously, output results in txt, csv, xlsx, or json depending on your workflow, and even route requests through Tor if you need to stay anonymous while you're hunting. Security researchers and privacy-obsessed folks low-key love it because it's completely free under the MIT license yet outperforms half the paid OSINT tools I've seen — and you can run it locally via Docker or skip installation entirely using Apify Actor in the cloud. For anyone doing brand monitoring, account takeover detection, or just trying to figure out their actual digital footprint, this is the move.
