Website Launch Auditor: SEO, Broken Links, Security & Pre-Launch QA (cursorFixPrompt)

Ship with confidence. Website Launch Auditor (MYSTIQUE LaunchShield) is a fast, $0-proxy pre-launch QA, SEO, broken-link, mobile UX, and security scanner built for indie hackers, SaaS founders, agencies, and developers shipping with Cursor, Windsurf, Cline, Lovable, Bolt.new, v0, Replit, Next.js, Astro, and Webflow.

Instead of handing you a generic PDF checklist, every audited URL includes a ready-to-paste cursorFixPrompt containing exact DOM selectors, HTTP headers, and step-by-step code instructions so you can fix every bug in Cursor, Windsurf, or Cline in a single prompt.

Why Developers & Agencies Use Website Launch Auditor

Modern coding tools (Cursor, Lovable, Bolt, v0) help you build an MVP in a weekend—but 90% of modern web apps ship with silent launch killers that tank conversions, SEO indexing, and security:

• Dead Placeholder Links & Copy: Unwired href="#" or javascript:void(0) buttons, hardcoded http://localhost:3000 links, and leftover Lorem ipsum / TODO: strings.
• Broken Social Preview Cards: Missing or relative og:image, og:title, og:description, and twitter:card tags that look broken when shared on X/Twitter, LinkedIn, Slack, Discord, or iMessage.
• Accidental Secret & Source Exposure: Publicly downloadable /.env files, exposed /.git/HEAD repositories, macOS /.DS_Store files, and production JavaScript sourcemaps (.js.map) that leak proprietary frontend code.
• Missing SEO & Crawl Foundations: Missing <meta name="description">, <link rel="canonical">, /robots.txt, /sitemap.xml, or Schema.org application/ld+json structured data.
• Mobile Layout & Accessibility Hazards: Missing width=device-width viewport tags, hardcoded inline pixel widths (>420px) that cause horizontal scrollbars on mobile phones, unlabeled <input> controls, empty icon <button> tags, and missing <img> alt attributes.
• Missing Security Headers & Mixed Content: Missing Strict-Transport-Security (HSTS), Content-Security-Policy (CSP), X-Content-Type-Options, X-Frame-Options, or insecure http:// assets loaded on https:// pages.

Copy-Paste Scheduled Automation (Python / n8n / cURL / GitHub Actions CI)

1. cURL (Instant Pre-Launch Check or Webhook Trigger)

curl -s -X POST \
  "https://api.apify.com/v2/acts/mystique-lab~website-launch-auditor/run-sync-get-dataset-items?token=YOUR_APIFY_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{
    "urls": ["https://your-staging-app.vercel.app", "https://your-production-domain.com"],
    "checkBrokenLinks": true,
    "checkExposedFiles": true,
    "checkSecurityHeaders": true
  }' | jq '.[0] | {url, launchReadinessScore, grade, launchReady, cursorFixPrompt}'

2. Python (apify-client)

from apify_client import ApifyClient

client = ApifyClient("YOUR_APIFY_TOKEN")
run = client.actor("mystique-lab/website-launch-auditor").call(
    run_input={
        "urls": ["https://stripe.com", "https://example.com"],
        "checkBrokenLinks": True,
        "maxLinksToCheckPerPage": 20,
        "checkExposedFiles": True,
        "checkSecurityHeaders": True,
    }
)

for item in client.dataset(run["defaultDatasetId"]).iterate_items():
    print(f"{item['url']} -> {item['launchReadinessScore']}/100 ({item['grade']})")
    if not item["launchReady"]:
        print("\n--- PASTE THIS INTO CURSOR / WINDSURF ---")
        print(item["cursorFixPrompt"])

3. GitHub Actions CI Gate (Block Deploys with Critical Bugs or Exposed .env)

name: LaunchShield Pre-Deploy Audit
on:
  deployment_status:
jobs:
  launch-audit:
    if: github.event.deployment_status.state == 'success'
    runs-on: ubuntu-latest
    steps:
      - name: Run MYSTIQUE LaunchShield on Preview URL
        run: |
          RESPONSE=$(curl -s -X POST \
            "https://api.apify.com/v2/acts/mystique-lab~website-launch-auditor/run-sync-get-dataset-items?token=${{ secrets.APIFY_TOKEN }}" \
            -H "Content-Type: application/json" \
            -d "{\"urls\": [\"${{ github.event.deployment_status.target_url }}\"]}")
          echo "$RESPONSE" | jq '.[0].cursorFixPrompt' -r
          CRIT=$(echo "$RESPONSE" | jq '.[0].criticalCount')
          if [ "$CRIT" -gt 0 ]; then
            echo "Critical launch issues detected! Paste the Cursor Fix Prompt above to resolve."
            exit 1
          fi

4. n8n / Make Scheduled Weekly Site Health Monitor

1. Add a Schedule Trigger (every Monday at 8:00 AM).
2. Add an HTTP Request node (POST https://api.apify.com/v2/acts/mystique-lab~website-launch-auditor/run-sync-get-dataset-items?token=YOUR_APIFY_TOKEN) with your client domains in urls.
3. Add an IF node checking {{$json.launchReadinessScore < 85 || $json.criticalCount > 0}} and route {{$json.cursorFixPrompt}} directly to your engineering Slack or Linear channel.
