Open source

See the code. Help shape what comes next.

CyberSim’s application code is available on GitHub. The contribution path is still taking shape, so this page starts with the doors that are genuinely open today.

Scenarios are where domain knowledge can meet the exercise.

Future scenarios can bring CyberSim’s decision-based learning into new settings and organizational challenges. A fuller contribution path is still being developed.

Contribution guidance is not yet available.

This prototype does not imply that contributor onboarding, scenario documentation, or submission workflows already exist.
