When mapping digital footprints, security analysts and open-source intelligence (OSINT) practitioners rely heavily on registration checkers.
For years, single-purpose utilities like Holehe were the industry standard for checking email recovery endpoints.
However, modern target profiling requires deeper correlation, higher concurrency, and cross-platform pivoting across both emails and usernames.
Enter —a high-throughput, 2-in-1 Python OSINT engine designed for deep email registration checking, username profiling, and cross-scan intelligence.

1.
Cross-Scan & Pivot Intelligence Engine Unlike legacy checkers that stop after returning a boolean hit, features an automated cross-scanning engine ().
It mines exposed handles, profile links, and secondary email addresses from initial scan metadata and recursively pivots across secondary target vectors. → Username: Extracts handles or social links exposed on an email's registered profile. → Email: Extracts public email addresses published on target profile pages.
Multi-Depth Chains: Supports configurable chain depth () and link validation rules ().
2.
Infostealer Breach Intelligence () Integrates directly with Hudson Rock's infostealer malware infection logs.
Running alongside an email or username scan instantly correlates targets against compromise logs and malware-exfiltrated credentials.
3.
High-Throughput Request Engine & Anti-Blocking Built on top of and , utilizes automated TLS fingerprint impersonation to defeat basic web application firewalls (WAFs) and rate-limiting.
It includes built-in proxy rotation with protocol auto-detection (, ) and health validation ().
Quickstart Usage Examples Single & Cross-Scan Pivot Execution High-Concurrency Output & Reporting Direct Python Integration (Library Mode) Conclusion For OSINT researchers looking for an active, modern, and extensible successor to Holehe, offers a comprehensive solution.
By pairing email enumeration with username profiling, TLS fingerprinting, infostealer intel, and recursive cross-scanning, it streamlines digital footprinting into a single CLI tool.
