Launch Check · New

We built an AI that tests your app before you launch

"It works on my machine" has a younger sibling that trips up every AI builder: "it works in preview." The preview is a controlled demo — the happy path, your data, your browser. Real users arrive with none of those advantages, and that's where AI-built apps quietly fall apart.

The gap between "preview works" and "it's ready"

When you build with Lovable, Bolt, Cursor, or Replit, the preview pane makes everything look finished. But the preview hides the things that actually break for real users:

• A button that goes nowhere because a route was renamed and a link wasn't updated.
• A page that throws a console error on load — invisible unless you open dev tools, which founders don't.
• An API call that 404s in production because an environment variable is missing on the live deploy.
• A screen that never finishes loading on a slower connection than your fast dev machine.
• A layout that collapses on mobile, where most of your first visitors actually are.

You'd catch these if you clicked through your live app like a stranger. But you don't — you click the two paths you always test, on the machine you always use, and everything looks fine.

So we made an AI do the clicking

VibeSafe Launch Check is an AI agent that opens your deployed app in a real browser and behaves like a first-time visitor. It:

• Visits your pages and follows the internal links a real user would click
• Captures screenshots of what actually renders
• Records console errors, failed network requests, and slow-loading screens
• Then writes a plain-English launch-readiness report with a score out of 100 — what worked, what's broken, why it matters, and what to fix first

You paste your URL, wait about thirty seconds, and get the report a QA tester would give you — without hiring one.

Safe by design: it looks, it never touches

Launch Check is deliberately read-only. It's a passive journey: it navigates and observes, but it never submits forms, makes purchases, or clicks destructive buttons on your live app. It's the equivalent of a careful reviewer browsing your site — not a bot poking every button. So you can point it at production without worrying it'll create junk data or fire off a real order.

When to run it

• Right before you share the link with users, clients, or investors
• After every deploy that changes routing, auth, or a major page
• When something "feels off" but you can't reproduce it on your machine
• Before a launch post — so the first 100 visitors don't find the bug you didn't

Pair it with a code scan and you've covered both halves of shipping safely: the code (exposed keys, injection, weak rules) and the running app (what a real user actually experiences).
