VibeFix
An AI agent that signs up to your live app like a new person. For each problem it confirms, it tells your AI tool what to fix. Every app gets one free check.

Documentation
You’re always signed in, so you never see what a new user sees. Our AI agent tries to sign up to your live app as a brand-new person, with a real inbox, on a phone and a computer, and shows you what it saw, with screenshots. For each problem it confirms, it tells your AI tool what to fix: where it is, the likely cause, and how you’ll know it’s fixed.
