WHY DEBUGMASTER

Every great developer
has chased a bug.

We made that chase a little more fun—and a lot more useful.

01 THE IDEA

DebugMaster began as a student project with one simple thought: the best way to learn programming is to get curious about what breaks.

Created by Belanna Avetisyan and Kamo Yergenyan, the project turns common coding mistakes into hands-on challenges. Try an idea, spot the cause, and understand the fix—without being afraid to get it wrong first.

Our mascot BelKa is always on the trail. Every bug she catches is another chance to learn something that sticks.
