The AI-native QA layer for vibe-coded apps.
Claude ships fast. It also ships bugs a human would catch in 10 seconds. QC Pro runs your live app like a real user — signs in, reads emails, fills forms — then hands Claude Code a ranked punch list of fixes it can apply without leaving your editor.
New users hit a broken page after they sign up
The welcome email's verify link sends people to a page that doesn't exist. Every new signup dead-ends before they see the product.
- signed up as a new user
- welcome email arrived (7s)
- clicked the verify link
- page returned 404
Three steps. Mostly ours.
You give us a URL. We do the clicking, the cursing, and the paperwork. You get fixes.
Point it at your app
Paste a URL. QC Pro spins up a real browser, logs in like a real user, and starts poking around like a curious intern.
Watch what breaks
A short, honest list: broken flows, dead CTAs, mobile layouts that fold in half, checkout that silently fails for half your customers.
Fix in Claude Code
Each finding ships with a diff, file references, and a verify-it-worked command. Hook up MCP and Claude applies them in your session.
Twelve ways your perfectly fine app is, in fact, not fine.
End-to-end, every run. No skipped cases, no green builds that lie.
Core flows work
Every button, form, and path does the thing you promised.
Signup & login
Accounts get made, passwords reset, sessions don't vanish.
Emails actually deliver
Welcome/verify/reset emails arrive - and their links go somewhere.
Looks right on phones
Your layout holds up on the 4 screens your users actually use.
Nothing looks broken
No overlapping text, no cut-off cards, no missing images.
Feels fast
First paint quick, and it doesn't melt once someone's using it.

Checkout works
Money moves. Subscriptions stick. Webhooks fire.
Third-parties load
Google sign-in, analytics, and embeds don't silently 404.
Basic security hygiene
Common holes - exposed keys, injection, missing headers - flagged.
Usable for everyone
Keyboard, screen reader, contrast - not an afterthought.
Catches regressions
Scores what changed vs last run, so Friday ships don't ruin Monday.
Does what it says
If your homepage promises X, we check that the product actually does X.

Every finding is reproducible, scoped, and comes with a fix.
Every finding is something a human could reproduce, with a proposed fix written in code - not a vague suggestion.
What happened
The verify link in the welcome email points to /confirm-email, but that route doesn't exist - it was renamed to /verify last week. Every new signup dead-ends before they see the product.
Repro steps
- 01Signed up with a fresh email
- 02Welcome email arrived (7s)
- 03Clicked 'Verify your email'
- 04Got a 404 page - back button dead too
Proposed fix
// app/verify/route.ts - rename or add redirect- export const path = '/confirm-email';+ export const path = '/verify';+ // add redirect for old links:+ export const redirects = { '/confirm-email': '/verify' };
Two plans. No bug is safe.
We don't charge per seat, per repo, or per vibe.
