Investigator Use

WhatsMyName (whatsmyname.app) is an open-source username enumeration tool that checks a specific username against hundreds of websites and social platforms, providing comprehensive cross-platform account discovery. It draws from a community-maintained database of sites and search patterns maintained on GitHub.


For OSINT investigators, WhatsMyName is one of the most comprehensive and regularly updated cross-platform username search tools available. Its open-source, community-maintained site database means it is continuously expanded with new platforms as they gain relevance.


The breadth of platform coverage distinguishes WhatsMyName from commercial alternatives — it includes major social networks, niche forums, gaming platforms, developer sites, cybercrime forums (for research purposes), adult platforms, and many others. This comprehensive scope is essential for investigators who need assurance that all platform categories have been checked.


Custom site list capability allows investigators to extend coverage with platforms specific to their investigation context — adding local or regional platforms relevant to the geographic area of investigation, or specialized platforms relevant to a specific industry or community.


False positive handling is built into WhatsMyName's design — the site database specifies expected success and failure response patterns for each platform, reducing incorrect "found" results that plague less sophisticated tools.


API access to WhatsMyName's functionality enables integration into automated investigation workflows and OSINT frameworks, allowing programmatic cross-platform username searches within larger investigation pipelines.


For investigators who need to confirm that cross-platform username research has been systematic and comprehensive, WhatsMyName's open-source database provides a transparent, auditable list of all platforms checked — suitable for documentation in investigation reports.


Document the username searched, WhatsMyName version and database version used, all platforms where accounts were found, and query timestamp.
