WhatsMyName
Community-maintained dataset and web tool for enumerating a username across hundreds of sites.
Technical Architecture & Overview
WhatsMyName, started by Micah Hoffman (WebBreacher), maintains a curated JSON dataset of hundreds of websites and the URL patterns that reveal whether a username exists on each. The hosted web interface runs the enumeration for free, and multiple CLI tools consume the same dataset. It complements Sherlock by providing the maintained data layer that several tools build on.
Targeted Technical Use Cases
Username attribution across social and forum sites during authorized investigations.
