Real app. Real bugs. No hints. Your AI. Your score.

How It Works

01

Get the app

You get a full running e-commerce app in your browser. Looks normal. Mostly.

02

Find the bugs

Click around. Find what's broken. Nobody tells you where to look.

03

Describe & fix

Describe the bug and submit your fix. Use any AI tool you want.

04

Hidden tests score you

Hidden test suites score your fix. If your fix breaks something else, you lose points.

05

Compete live

Live leaderboard. 3 hours. Top scores win.

“This isn't usual Competitive Programming. Nobody tells you the problem. You find it yourself. That's the job.”
