Flat (brute-force)

A high-velocity, Go-based engine built for modular credential testing and rapid protocol validation.

Flat is a lean engine built for high-concurrency testing: it handles 500+ simultaneous threads with minimal memory overhead. The architecture is modular (supporting SSH, FTP, and HTTP) and relies on simple flat-file wordlists for immediate deployment. It is a portable, no-nonsense binary that delivers raw throughput for red teamers and security researchers. Use this tool when you need a fast, reliable way to audit authentication layers without the bloat of larger frameworks.
