What does PreLaunchQA check?

PreLaunchQA loads your web app in a real Chromium browser and checks for console errors, failed network requests, broken links, missing meta tags, images without alt text, form fields without labels, mixed content issues, and more. Every finding includes raw browser evidence.

Who is PreLaunchQA for?

PreLaunchQA is built for developers using modern frameworks and AI coding tools like Next.js, React, Bolt, Cursor, and v0 who want to verify their web apps actually work in a real browser before going live.

How is PreLaunchQA different from Lighthouse or PageSpeed?

PreLaunchQA focuses on functional correctness — real browser console errors, network failures, and dead links — rather than performance scores. It verifies domain ownership before scanning, provides before/after comparison diffs, and targets runtime errors in production.

Yes, the Sample Scan is free and gives you a single-page check with full raw browser evidence. For deeper audits, the Launch Check is $49 one-time and the Monthly Re-test plan is $99/month for unlimited checks.

Do I need to give PreLaunchQA access to my code?

No. PreLaunchQA only needs the URL of your live or staging site. It loads the page in a browser just like a real user would. You verify domain ownership via DNS record, meta tag, or file upload before any check runs.

Does PreLaunchQA work with apps built in Next.js, React, Cursor, or Bolt?

Yes! PreLaunchQA is specifically optimized for modern web applications generated by Next.js, React, Cursor, Bolt.new, and v0. It catches silent runtime console errors, unhandled async states, broken routes, and missing meta tags before your users encounter them.

EXECUTIVE SUMMARYSlide 1 of 8

PreLaunchQA: The Autonomous Browser QA Cloud

Real headless Chromium inspection for modern web applications before going live.

Modern web applications built with AI assistants (Cursor, Bolt, Next.js, React) ship code faster than ever. However, traditional linters and static tests fail to detect runtime console errors, failed async fetches, and broken routes.

⚡

Zero Code Access

We never need repository access. Audits run from public URLs.

🌐

Real Headless Chromium

DevTools console, network waterfall, and accessibility logs.

🛡️

Verified Ownership

DNS TXT or Meta tag verification ensures complete security.

THE PROBLEMSlide 2 / 8

The 'Runtime Blind Spot' in Modern Web Development

Code compiles cleanly, but crashes when real users interact with the browser.

Why Traditional QA Tools Fail:

✕Theoretical Performance Scores: Lighthouse gives an arbitrary 95 score while critical buttons throw unhandled JavaScript TypeError in the console.
✕Silent Auth Redirect Traps: Custom domain OAuth callbacks redirect to broken URLs with zero server alerts.
✕Ghost Assets: Images without alt tags, mixed content HTTP assets on HTTPS pages, and dead 404 navigation links destroy SEO and user trust.

PreLaunchQA bridges this gap by giving developers unfiltered, raw browser evidence rather than high-level opinions.
