One platform. Every licensing scenario.
TrialKey is a licensing system that helps developers of web sites and software manage the process of licensing and user management for their applications and services. Whether you want to offer a 14-day free trial before purchase, distribute license keys for downloadable software, or manage subscriptions for a web app — TrialKey handles it all with a handful of API calls.
Our zero-install approach means the same methodology works identically for web sites, mobile apps, and installed desktop software — no extra dependencies required on the client. Licensing is based on a username and password paired with a unique installation key, validated server-side.
To get users up and running even faster, TrialKey provides pre-built, brandable Quick Link screens for common actions like trial sign-up (with email confirmation) and password changes. Point users to your branded URL — no custom workflow code needed. Of course, the full REST API is always available if you prefer complete control.
