Mikros is now available for all users.

Worry less. Release more.

Privacy & Security First

All passwords are hashed, and developers cannot view user email addresses. Your data stays safe.

Easy Code, Great Support

We provide example code in multiple languages, a well-documented API, and fast support to help you succeed.

Ready to Scale

From 30 users to 30,000, System Locker grows with you.

Constantly Improving

New updates ship regularly and bugs get crushed fast. We won’t leave you hanging.

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.

Key-only auth — no user accounts required. Keys still lock to HWID on first use.

Session-based auth with dynamic responses and strictly-timed heartbeats keep debuggers and key-sharers at bay.

Vanity Keys

License keys include your system name, and they’re shorter too.

Reseller / Admin Panel

Give resellers and admins access to your software with fully custom permissions.

Management API

Generate keys or reset HWID easily. Perfect for Discord bots.

Paid Support

$20/hr for the first 3 hours, $40/hr after. Total time determined monthly. Or reach out on Discord for quick questions.
