Ready to Scale
From 30 users to 30,000, System Locker grows with you.
Constantly Improving

Premium features provide total control.
Powerful API
Build Discord bots, management tools, and upsell your users directly within your app using our API.
Reseller Panel
Give resellers access to key generation for your software. Fine-grained permissions mean a reseller can be blocked from seeing everyone else’s keys.
Admin Panel
Give admins and staff access to key generation and actions for your software.
Each admin gets their own set of permissions — ban, freeze, and reset HWID as needed.
