v0 app testing
Test a v0 app with a real browser
v0 can get you from prompt to interface quickly. VibeTester checks whether the deployed experience holds up outside the editor.

Scan my appWhat VibeTester checks
- Finds buttons with no visible response
- Reports JavaScript crashes and failed page requests
- Checks for sideways scrolling on mobile
- Flags missing metadata and common security header gaps
Why check before you share?
An interface can look complete while the deployed route, form action, or responsive layout is not. Test the version your users will actually open.
How it works
Paste the deployed v0 URL, not an editor link. VibeTester focuses on the public browser experience and returns a report you can use in v0, Cursor, or Lovable.
