Lighthouse Fixer

Lighthouse tells you what's wrong but the fix suggestions are generic. This tool runs Lighthouse and gives you specific, actionable fixes for your issues.

One command. Zero config. Just works.

Quick Start

npx ai-lighthouse https://mysite.com

What It Does

• Runs full Lighthouse audit on any URL
• Analyzes the results with AI
• Provides specific fixes, not generic advice
• Prioritizes issues by impact

Usage Examples

# Audit your site
npx ai-lighthouse https://mysite.com

# Specific page
npx ai-lighthouse https://example.com/page

# Focus on performance
npx ai-lighthouse https://mysite.com --category performance

Best Practices

• Fix performance first - biggest impact on user experience
• Test on slow connections - not everyone has gigabit
• Check mobile separately - mobile scores are often worse
• Iterate - fix one thing at a time

When to Use This

• Lighthouse scores are tanking
• SEO audit flagged performance issues
• Core Web Vitals are failing
• Want actionable advice, not documentation links
