Why Kybr

Anyone can build now.
But shipping safely is different.

Vibe coding with AI has made it possible for anyone to build a product.
But "it works" and "I can ship it confidently" are two different things.
Kybr was built to close that gap.

Problem 01

I need someone to check my app before I ship

Not big enough to hire a QA firm, but too uncertain to go it alone. There's no easy way to get an outside eye on your app.

"I just want someone to tell me it's actually working."

Problem 02

I know there are bugs. But testing feels like too much work

Testing sounds important, but the process is unclear and tedious. So bugs pile up until users find them first.

"I know I should test, but I have no idea where to start."

Problem 03

AI fixes break other things — and burn through credits

Ask AI to fix a bug and something else breaks. Go in circles for hours. Without the root cause, AI just patches symptoms.

"Fixed one thing, broke another. Back to square one."
