From URL to tested
in three steps.

No setup. No config. No engineers needed.

01

Scan your app

Paste your URL and we run a real browser against it. We surface every element that will cause tests to fail — missing labels, fragile selectors, duplicate names.

02

Fix with AI prompts

Every issue generates a copy-paste fix prompt for Cursor, Lovable, or Bolt. Your testability score updates on re-scan so you can see progress.

03

Test in plain English

Describe what to test. We run it in a real browser — clicking, typing, asserting. Video captured, failure explained in plain language. Group into suites and run on every deploy.

Your app has a
testability score.

Before you can test anything, your app needs to be testable. Most vibe-coded apps aren't — and you'd never know until a test silently fails.

  • Scans for missing aria labels, duplicate names, weak selectors
  • Visual issue overlay — see exactly where problems are
  • Scored out of 100 — track improvement over time
  • Free forever

The "submit" button on your checkout form is missing an accessible label. Add aria-label="submit order" so testing agents and screen readers can identify it reliably.
