AI Agent vs a Vibe-Coded App: 5 of 5 Bugs, Plus One Nobody Planted
Can an AI testing agent find bugs in a vibe-coded app it has never seen? On 22 October 2026 we tried it live on YouTube. We planted 5 bugs in a food-delivery demo app, added a new feature with one prompt, and pointed the Wopee.io agent at it with a 4-line ticket and the app's business rules. Not the bugs.
It found all 5. Three with the exact steps from our answer key, two by their symptoms. Zero false alarms.
And it found one more that nobody planted.
Here is the scoreboard, how it got there, and what didn't go well.
