Everything you need to ship with confidence
Diffie handles the hard parts of software licensing so you can focus on what matters.
Multi-App Management
Manage licenses across every project from a single admin panel. Templates, files, and keys — all organized per application.
Hardware-Bound Protection
Each license locks to a specific machine via HWID binding. No sharing, no workarounds, no piracy headaches.
Real-Time Sessions
See exactly who's using your software right now. Monitor active sessions, detect abuse, and kick unauthorized users instantly.
Customer Self-Service
Your users redeem keys, manage licenses, and request HWID resets through their own portal — without emailing you.
