Your AI agent is online

Can a brand-new person actually sign up to your app?

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.

Free. No account needed to run it. About 5 minutes.

Our AI agent signs up once as “VibeFix Test” with a test address. It never changes your app, never sees your passwords and never emails your users.
