LeakPeek

LeakPeek is a Tor-only breach search and leak aggregation platform designed to help users determine whether emails, usernames, or identities have appeared in known data breaches. The service aggregates verified breach datasets and allows unregistered users to perform basic email lookups, while registered users gain deeper access to curated dumps and extended search options.

The platform focuses on breach legitimacy, applying verification steps such as structural analysis, cross-referencing public disclosures, and comparison against existing breach databases. LeakPeek does not log search queries and operates without tracking cookies, emphasizing operational privacy. Advanced access is gated behind invite-based registration using PGP authentication, eliminating the need for passwords or email accounts.
