Username Recon · browser edition

Find a handle everywhere at once.

Enter a username or a real name. It fans out into likely handle variants, ranks them by similarity, then checks platforms — automatically where the browser is allowed to, and as one-click links everywhere else.

Reliable auto-checks: GitHub and Chess.com (their APIs allow browser access). Other platforms can't be read directly from a web page (CORS) — they show as open-in-tab links, or are attempted via proxy if you enable it. For dependable scanning across ~400 sites, run the Python/FastAPI version with the full Sherlock dataset via SITES_DATA=…/data.json . Use this to check availability or audit your own accounts, and respect each platform's terms and rate limits.
