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.

Frequently asked questions

How long does domain ownership verification take?

Meta tag and file verifications are validated immediately (under 3 seconds). DNS TXT record propagation depends on your DNS provider, typically taking between 2 to 30 minutes. You can retry up to 10 times per hour.

What does the browser scan actually test?

Our worker spins up an isolated Chromium browser instance, visits your target URL, waits for network idle, and inspects console errors, failed network calls, broken links, image alt attributes, form label accessibility, mixed content, and responsive layout.

Are credentials or private customer data stored?

Never. Current checks only run on public entry points. When authenticated test flows are enabled, credentials are kept in an encrypted ephemeral vault and permanently purged 24 hours after check completion.

How does the re-scan comparison diff work?

When you re-run a check on an app, our comparison engine correlates rule IDs and page paths against your previous completed run, highlighting newly fixed issues, brand-new defects, and persistent bugs.
