🔍 Google Lighthouse Web Quality Checker

Run full Google Lighthouse audits on any web page using a built-in Lighthouse CLI and headless Chrome — no API key required. Get scores and detailed reports for Performance, Accessibility, SEO, and Best Practices.

🔥 How It Works

This Actor runs the Google Lighthouse CLI with headless Chromium inside a Docker container, performing the same audits you'd get from Chrome DevTools — but fully automated and at scale.

Audit Categories:

• Performance: FCP, LCP, TBT, CLS, Speed Index, TTI
• Accessibility: How well the page supports users with disabilities
• Best Practices: Adherence to modern web development standards
• SEO: Search engine optimization metrics

🛫 How to Use

1. URLs to Audit: Enter one or more web page URLs, e.g. https://www.example.com
2. Audit Categories: Choose which categories to audit, separated by commas. Options:
   • performance - Performance
   • accessibility - Accessibility
   • best-practices - Best Practices
   • seo - Search Engine Optimization
   • Leave empty to audit all categories
3. Device Type: Choose mobile (phone emulation) or desktop (desktop emulation)
4. Click Save & Start to begin the audit
5. Export results in JSON, XML, CSV, Excel, or HTML format

Note: Lighthouse audits are resource-intensive (approximately 30-60 seconds per URL). We recommend allocating at least 2048 MB of memory for this Actor.
