Something feels off
The app works — mostly. But something in the back of your mind says it's not ready. You just can't put your finger on it.
"It kind of works. I think."

The problem
The bugs hiding in your app
are the ones users find first.
Most issues in vibe-coded apps don't show up during development. They live in flows you never thought to check — and your users find them before you do.
No idea what to check
You built it, so you know how it's supposed to work. But that's not the same as knowing what a real user will break.
"Works fine on my machine."No testing know-how
Without a testing background, you don't know which parts of your app are risky, what to look for, or whether it's actually safe to ship.
"I have no idea if my app is actually working properly."From detection to fix

We know where
apps break.
Years of testing real apps taught us which flows fail most. We've encoded that knowledge directly into Kybr — so you don't need to know what to test. We already do.
