The Challenge

Building a license system that works across Windows, macOS, Linux, mobile apps, browser extensions, and web applications is no small feat. Here is how we did it.

Key Design Decisions

We chose a REST API-based approach with device fingerprinting and activation tokens. This allows any application on any platform to integrate with our license system using simple HTTP calls.

Security

Every license key follows the format LS-XXXX-XXXX-XXXX-XXXX and is cryptographically generated. Activation tokens are UUID-based and tied to specific device fingerprints.
