Holehe: Check Where Your Email is Begin Used (OSINT)

What is Holehe?

Holehe is a powerful Python-based OSINT tool that allows you to discover whether an email address is registered on over 120+ online platforms, including major services like Twitter, Instagram, Snapchat, Imgur, and more.

It works by leveraging the "password reset" functionality commonly found on websites, safely checking for account existence without sending any emails or notifying the target . This makes it ideal for discreet reconnaissance during security audits or digital investigations.

Holehe is designed for efficiency and privacy: it doesn't trigger alerts on the target side and supports rate-limit detection to avoid blocks, with recommendations to rotate IPs if needed.

Built for both command-line and programmatic use, it integrates seamlessly into scripts and workflows. Whether you're a penetration tester, investigator, or developer, Holehe delivers fast, structured results in a standardized JSON-like format, including partial recovery emails, phone numbers, and service-specific data.
