What is Keygen?
Keygen is a licensing-as-a-service API for software developers. Keygen offers licensing policies that allow you to offer and control various types of licenses from node-locked licenses to time-limited trials. It includes identity management features "to support multiple licenses per-user, and allow users to perform self-management actions for their licenses and machines."
