Everything you need to license software
One platform for issuance, enforcement, payments and insights.

Every model
Node-locked, floating, subscription, usage-based, trials, site and user-based licensing.
Payments built in
Stripe checkout, recurring subscriptions and metered usage tied directly to license keys.
Analytics & insights
Activation, device and usage analytics with anomaly detection to spot issues early.
Enterprise ready
SSO/SCIM, RBAC, audit logs, residency options and a documented security posture.
How it works
Create a product
Organize keys per application and define feature flags.
