## Description

Keygen is a software licensing and distribution API platform designed to validate product keys, manage user entitlements, and enforce device activation policies. It provides a comprehensive set of identity and licensing services that enable software vendors to control access to desktop and server applications while tracking usage limits and seat counts across hardware machines.

The platform includes enterprise identity provider integration using standard SAML protocols, single sign-on authentication, and role-based access control with granular permission restrictions to secure system operations. Administrative events and incoming API calls are captured in isolated audit logs to maintain complete historical records and track accountability. 

Additional capabilities support environment-based resource scoping, multi-environment management, containerized self-hosting with automated database migrations, and asynchronous background job queuing via an in-memory data store. Data migration tools facilitate cross-instance transfers between self-hosted installations and cloud environments.
