I build custom licensing systems for software vendors who need to control product activation, subscriptions, installations, devices, servers, feature access, and usage limits. The system can issue license keys and access tokens, validate active subscriptions, bind licenses to approved installations, revoke access, record usage, and provide administrative diagnostics.

Licensing can be integrated with desktop software, web platforms, bots, Android applications, customer billing systems, and white-label products. The platform can include product plans, feature flags, activation endpoints, audit logs, license status pages, update access, and automated fulfillment after payment.
