Enterprise-grade licensing infrastructure without the complexity of legacy vendors or the limitations of simple tools. From cloud-native to offline and air-gapped deployments, LicenseSpring is the only modern, ISO-certified platform that treats your specific edge cases as core features, not workarounds.
Trusted by leading software vendors
Three integrated layers: entitlements, monetization, and distribution, working continuously across cloud, on-premise, and air-gapped environments.

if ( license->isValid() && !license->isExpired() )
std::cout << "Licensed! Days remaining: " << license->daysRemaining() << "\n";Issue, validate, and revoke licenses via REST API across cloud, on-premise, and fully air-gapped environments. Supports node-locked, floating, consumption-based, subscription, and time-based models.

Whether your product runs on a server, workstation, personal computer, mobile device, PLC, embedded system, or IoT gateway, LicenseSpring has you covered. And with support for all common programming languages, your development team can integrate licensing into any stack without friction.
LicenseSpring fits into the tools you already use.
