WhatsMyName: Username enumeration across websites
JSON dataset for checking username availability across hundreds of websites for OSINT tools.
Learn more about WhatsMyName
WhatsMyName is an open-source project that maintains a comprehensive JSON dataset for username enumeration across web platforms. The system works by providing detection rules that analyze server responses to determine whether a username exists on a given website. The JSON file contains site-specific detection patterns that third-party tools can consume to perform automated username searches. The project focuses exclusively on maintaining the dataset rather than providing checker tools, serving as a data source for numerous OSINT applications and username verification services.
Detection Accuracy
Uses response pattern matching to minimize false positives that plagued earlier username checkers. Each site entry includes specific detection rules for reliable username verification.
JSON Dataset
Provides a structured data file that can be consumed by any tool or application. The format allows easy integration into existing OSINT workflows and custom implementations.
Community Maintained
Accepts submissions from contributors worldwide to expand site coverage. The dataset is continuously updated with new platforms and detection improvements.
// Direct username lookup via URL parameter
// Basic usage:
https://whatsmyname.app/?q=USERNAME
// Example with actual username:
https://whatsmyname.app/?q=john
// This allows programmatic integration by constructing URLs
const username = 'targetuser';
const wmn_url = `https://whatsmyname.app/?q=${username}`;
