# KEYZY

> KEYZY is a software licensing platform for desktop and plugin developers
> (C++, JUCE/audio plugins, C#). It handles license generation, activation,
> validation, trials, upgrades and offline licensing via a C++ static library
> and a REST API. Credentials compile into the binary; the static library
> resists API-hooking, unlike DLL-based licensing schemes.
