Frequently Asked Questions

Everything you need to know about VibeTester

Can I test localhost?

VibeTester requires a publicly accessible URL. However, you can use ngrok.io or localhost.run to expose your localhost, then test that URL for free!

What's a preview URL?

A preview URL is a temporary staging/preview URL provided by platforms like:

  • Vercel: myapp.vercel.app
  • Netlify: mysite.netlify.app
  • Railway: myapp.up.railway.app
  • Cloudflare Pages: mysite.pages.dev
  • And 40+ more platforms!
These are always free to test with our full 11,699+ test suite.

Why can't I test my client's domain?

Free tier requires your email domain to match the test domain (e.g., if you're john@example.com, you can test example.com). This ensures proper authorization and prevents unauthorized testing.

To test client domains:

  • Pro Plan ($50/mo): Test 2 client domains with permission certification
  • Service Provider ($100/mo): Test 10 domains
  • Team ($75/seat, min 3): Test 5 domains per team
