Ship without the anxiety

Your app gets an expert reviewer.You don't lift a finger.

VibeCheck is an AI agent that explores your web app the way a meticulous QA engineer would—clicking through flows, trying edge cases, breaking things on purpose. When it finds issues, it tells you exactly what's wrong and how to fix it.

No test scripts. No maintenance. Just point it at your URL.

It's like hiring a QA engineer who never sleeps

The agent reads your codebase, understands your routes, and systematically tests every user flow it can find. Not random clicking—intentional, thorough exploration.

01

Reads your code

Connects to your repo and actually understands your components, routes, and data flow. Tests are contextual, not generic.

02

Explores like a user

Real browser, real clicks, real form submissions. Tries weird inputs, rapid actions, back-button abuse—things real users do.

03

Writes the fix

Every issue comes with a specific code suggestion. Not “fix this bug”—actual patches you can apply or adapt.
